Description

Technical Field

[0001] The present application relates to the technical field of rotorcraft testing, and in particular to a performance testing system and method for a magnetically levitated rotor power system. Background Art

[0002] At present, various applications of magnetic levitation technology are in the ascendant at home and abroad, and the more mature applications are mainly concentrated in magnetic levitation trains. In recent years, with the continuous development of magnetic levitation technology, the application of magnetic levitation technology to rotorcraft has become a new design idea for rotorcraft. From this, the magnetic levitation rotor power system has been derived.

[0003] At the same time, the testing technology for the performance of the magnetic levitation rotor power system is still immature. For example, Comparative Document 1 (Announcement No. CN215641703U, patentee Zero Gravity Nanjing Aircraft Industry Co., Ltd.) discloses a multi-rotor UAV power system measurement test bench, including a lever mechanism, an adjustment unit, a frame unit, a power unit, a pressure test unit and a test unit. The frame unit includes a test bench and a support seat. The middle part of the lever mechanism is arranged on the support seat, the front end of the lever mechanism is provided with a test unit, and the rear end is provided with an adjustment unit and a counterweight. The adjustment unit includes a slide rail, a flange and a push rod arranged in sequence from top to bottom. The test unit includes several motor test pieces and blade test pieces installed at the front end of the lever mechanism. Comparative Document 1 can adjust the position of the push rod and the pressure sensor through the slide rail, measure the propeller tension multiple times, and measure the current and voltage flowing through the motor through the shunt. It can be seen that Comparative Document 1 can only test the propeller tension and the current and voltage data of the motor.

[0042] Since comparative document 1 can only test the thrust of the propeller and the current and voltage data of the motor, the above test data has the deficiency of not being able to provide comprehensive data support for the performance evaluation of the power performance, suspension stability performance, drive control performance, etc. of the magnetic levitation rotor power system 1 (i.e., the lift of the magnetic levitation rotor power system 1, the speed of the motor of the magnetic levitation rotor power system 1, the current of the motor drive coil 17 of the magnetic levitation rotor power system 1, the voltage of the motor drive coil 17 of the magnetic levitation rotor power system 1, the gap between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1 in the axial direction (Y axis), and the gap between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1 in the radial direction (X axis)). The improvement of the present application is to provide a performance test system for a magnetic levitation rotor power system consisting of an environmental simulation unit 3, a test bench unit 2, a sensor unit 5 and a test control unit 4, so as to achieve the technical effect of providing a comprehensive data basis for the evaluation of the power performance, suspension stability performance, and drive control performance of the magnetic levitation rotor power system 1. The specific implementation method is as follows.

[0043] Example 1

[0044] like Figure 1 A performance test system for a magnetically suspended rotor power system is shown, comprising:

[0045] The environment simulation unit 3 can simulate the test environment required by the magnetic levitation rotor power system 1 in the test according to the requirements, such as the flight attitude of the magnetic levitation rotor power system 1 (mainly refers to the inclination angle of the magnetic levitation rotor power system 1 relative to the horizontal plane), the magnitude of different wind speeds encountered by the magnetic levitation rotor power system 1, and the rain environment of the magnetic levitation rotor power system 1;

[0046] The test bench unit 2, the magnetic levitation rotor power system 1 is installed on the test bench unit 2; the test bench unit 2 provides test conditions for the magnetic levitation rotor power system 1, that is, the actual operating state of the magnetic levitation rotor power system 1 in the performance test meets the operating requirements of the rotorcraft;

[0047] The sensor unit 5 includes a plurality of sensors, and the plurality of sensors collect data of the magnetic levitation rotor power system 1 under various working conditions (i.e., the state of the magnetic levitation rotor power system 1 in specific operation), such as the lift of the magnetic levitation rotor power system 1, the rotation speed of the motor of the magnetic levitation rotor power system 1, the current of the motor drive coil 17 of the magnetic levitation rotor power system 1, the voltage of the motor drive coil 17 of the magnetic levitation rotor power system 1, the gap between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1 in the axial direction (Y axis), and the gap between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1 in the radial direction (X axis);

[0048] The test control unit 4 is electrically connected to the magnetic levitation rotor power system 1, the test bench unit 2, the environmental simulation unit 3 and the sensor unit 5. Specifically, the electrical signal connection is through the RS-485 serial interface and adopts the Modbus RTU protocol. Since the Modbus RTU protocol is a widely used serial communication protocol, it is based on a master-slave architecture and is suitable for data exchange between devices in the field of industrial automation. The Modbus RTU protocol communicates through a serial line and supports the RS-485 serial interface. The RS-485 serial interface is recommended for industrial applications due to its robustness, long communication distance and support for multi-point networks. Therefore, by adopting the above-mentioned serial interface and serial communication protocol, the stability of the electrical signal transmission between the test control unit 4 and the magnetic levitation rotor power system 1, the test bench unit 2, the environmental simulation unit 3 and the sensor unit 5 can be ensured.

[0049] Among them, the test control unit 4 outputs a control signal and receives data collected by the sensor unit 5. Specifically, the test control unit 4 includes an environment simulation unit control module, a test bench unit control module, a magnetic levitation rotor power system suspension control and drive control module, and a sensor information processing module. The environment simulation unit control module sends a current or voltage signal to the environment simulation unit 3 through an RS-485 serial interface to simulate various test environments required by the magnetic levitation rotor power system 1 in the test experiment. The test bench unit control module sends a current or voltage signal to the test bench unit 2 through an RS-485 serial interface to provide test conditions for the magnetic levitation rotor power system 1. The magnetic levitation rotor power system suspension control and drive control module sends current and voltage signals to the motor drive coil 17, the axial suspension coil 15 and the radial suspension coil 18 through the RS-485 serial interface, and adjusts the driving force of the motor and the suspension force of the suspension system in real time to maintain the steady-state operation of the magnetic levitation rotor power system 1. The sensor information processing module uses the Modbus RTU protocol to parse and process the data collected by the sensor unit 5.

[0050] At the same time, in order to more intuitively display the data collected by the sensor unit 5, the performance test system of the magnetic levitation rotor power system also includes an intelligent terminal 6. Specifically, the main types of intelligent terminal 6 include mobile intelligent terminals and non-mobile intelligent terminals, among which mobile intelligent terminals include smart phones, tablet computers, smart wearable devices, etc.; non-mobile intelligent terminals include smart home appliances, smart display screens, etc. The test control unit 4 parses the data collected by the sensor unit 5 and transmits it to the intelligent terminal 6 synchronously through the Ethernet port after processing. The intelligent terminal 6 displays the data on its display. The data display can be divided into discrete data change display, curve change, etc., which is convenient for researchers to observe the test data, and then evaluate the power performance, suspension stability performance, drive control performance, etc. of the magnetic levitation rotor power system 1 based on the data.

[0051] The performance test system of the magnetic levitation rotor power system in this embodiment includes an environmental simulation unit 3, a test bench unit 2, a sensor unit 5 and a test control unit 4. The test control unit 4 is electrically signal-connected to the magnetic levitation rotor power system 1, the environmental simulation unit 3, the test bench unit 2 and the sensor unit 5, respectively. Through the cooperation of the above-mentioned units, it is possible to effectively simulate various test environments of the magnetic levitation rotor power system 1, meet the requirements of its test experiments, provide comprehensive data support for the evaluation of the power performance, suspension stability performance, drive control performance, etc. of the magnetic levitation rotor power system 1, save the test cost of the magnetic levitation rotor power system 1, that is, one system can simulate various test environments and conduct multiple test experiments, thereby achieving the purpose of cost saving.

[0052] In order to make the actual operating state of the magnetic levitation rotor power system 1 in the performance test meet the operating requirements of the rotorcraft, such as Figure 2 and 3 As shown, in this embodiment, the test bench unit 2 preferably includes: a mounting portion 23; a support portion 21, the support portion 21 includes a clamping portion 22, and the clamping portion 22 is slidably mounted on the support portion 21. Specifically, the clamping portion 22 can achieve sliding cooperation with the support portion 21 through the structure of a slide rail and a slider. There are three support portions 21, and the three support portions 21 are respectively vertically mounted on the mounting portion 23. Specifically, the angle between the three support portions 21 and the mounting portion 23 is 90°.

[0053] The test bench unit 2 provided in this embodiment includes a mounting portion 23, on which three supporting portions 21 are arranged, and the supporting portions 21 and the mounting portions 23 are perpendicular to each other, and a clamping portion 22 is slidably connected to the supporting portion 21. Firstly, since the three supporting portions 21 are all slidably connected to the clamping portions 22, the positions of the clamping portions 22 can be adjusted respectively by sliding the clamping portions 22, so that each clamping portion 22 is located in the same horizontal plane, so that the three clamping portions 22 can be used to perform three-point planar support on the magnetic levitation rotor power system 1, thereby achieving stable clamping support for the magnetic levitation rotor power system 1 and limiting the position of the magnetic levitation rotor power system 1 to be parallel to the horizontal plane, and at the same time, the clamping and fixing of the magnetic levitation rotor power system 1 by the clamping portion 22 can constrain the magnetic levitation rotor power system 1 in the horizontal axis when working. rotation, and constrain its displacement in the horizontal direction. At the same time, through the sliding cooperation between the clamping part 22 and the supporting part 21, and the position limitation between the supporting part 21 and the mounting part 23, the magnetic levitation rotor power system 1 can make a linear motion in its axial direction when working. Therefore, the test bench unit 2 can constrain the horizontal circumferential rotation of the magnetic levitation rotor power system 1, constrain its horizontal displacement and limit the magnetic levitation rotor power system 1 to make a linear motion along its axial direction, so that the actual operating state of the magnetic levitation rotor power system 1 meets the operating requirements loaded on the rotorcraft (that is, the magnetic levitation rotor power system 1 can only move linearly along the axial direction of the magnetic levitation rotor power system 1, and will not rotate horizontally circumferentially in the magnetic levitation rotor power system 1 or displace in the horizontal direction).

[0054] In order to make the test bench unit 2 adapt to the installation of magnetic suspension rotor power systems 1 of different sizes and models, Figure 2 and Figure 3As shown, the test bench unit 2 preferably in this embodiment also includes: a driving part 24, the driving part 24 is installed on the mounting part 23, and the driving part 24 is connected to the support part 21; wherein the driving part 24 drives the support part 21 to move to adjust the distance between the support parts 21, and specifically, the number of the driving parts 24 can be adaptively matched according to the number of the support parts 21, and the driving part 24 can be a linear module, and the output end of the linear module is connected to the support part 21.

[0055] The test bench unit 2 provided in this embodiment also includes a driving part 24, which is drivingly connected to the support part 21. Since the driving part 24 is drivingly connected to the support part 21, the driving part 24 can drive the three support parts 21 to move respectively relative to the mounting part 23 and toward or away from the center point of the mounting part 23, so that the distance between the three support parts 21 can be adjusted according to the size of the magnetic levitation rotor power system 1, so that the distance between the three support parts 21 meets the size of the magnetic levitation rotor power system 1, thereby facilitating the installation of magnetic levitation rotor power systems 1 of different sizes.

[0056] In order to evaluate the power performance and drive control performance of the magnetic levitation rotor power system 1, Figure 1-3 As shown, the preferred sensor unit 5 of this embodiment includes: a force sensor 52, which is installed on the test bench unit 2, and the force sensor 52 collects lift data of the magnetic levitation rotor power system 1; a speed sensor 53, which is installed on the test bench unit 2, and the speed sensor 53 collects speed data of the motor of the magnetic levitation rotor power system 1; a voltage sensor 54, which is installed on the test control unit 4, and the voltage sensor 54 collects voltage data of the motor drive coil 17 of the magnetic levitation rotor power system 1; a current sensor 55, which is installed on the test control unit 4, and the current sensor 55 collects current data of the motor drive coil 17 of the magnetic levitation rotor power system 1; wherein the force sensor 52, the speed sensor 53, the voltage sensor 54 and the current sensor 55 are respectively connected to the test control unit 4 with electrical signals.

Secondly, the speed sensor 53 can collect the speed data of the motor during the test under different working conditions. Finally, the voltage sensor 54 and the current sensor 55 respectively collect the current and voltage data of the motor drive coil 17 during the test under different working conditions of the magnetic levitation rotor power system 1. Since each sensor is connected to the test control unit 4 with an electrical signal, the data collected by each sensor can be transmitted to the test control unit 4. Finally, the power performance of the magnetic levitation rotor power system 1 can be evaluated through the lift data and the lift-torque ratio data (the lift-torque ratio data is the ratio of the lift data to the torque data, and the torque data is calculated from the speed data, the voltage data and the current data), that is, the greater the lift, the greater the lift-torque ratio, and the better the power performance of the magnetic levitation rotor power system 1; by comparing the torque data (the torque data is calculated from the speed data, the voltage data and the current data) with the torque data calculated by the motor mathematical model evaluation, the torque fluctuation is analyzed, thereby verifying the driving control performance of the magnetic levitation rotor power system 1.

[0058] In order to evaluate the suspension stability performance of the magnetic suspension rotor power system 1, as Figure 1 and Figure 4 The embodiment shown is preferred, wherein the sensor unit 5 also includes: a gap sensor 56; the gap sensor 56 includes: an axial gap sensor, the axial gap sensor is installed at the gap between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1 along the axial direction of the magnetic levitation rotor power system 1, and the axial gap sensor collects the axial gap data between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1; a radial gap sensor, the radial gap sensor is installed at the gap between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1 along the radial direction of the magnetic levitation rotor power system 1, and the radial gap sensor collects the radial gap data between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1; wherein the axial gap sensor and the radial gap sensor are respectively electrically connected to the test control unit 4.

[0059] The sensor unit 5 in this embodiment includes a gap sensor 56, and the gap sensor 56 includes an axial gap sensor and a radial gap sensor. The axial gap sensor is installed in the gap between the rotor 12 and the stator 13 along the axial direction of the magnetic levitation rotor power system 1, and the axial gap sensor collects the axial gap data between the rotor 12 and the stator 13. The radial gap sensor is installed in the gap between the rotor 12 and the stator 13 along the radial direction of the magnetic levitation rotor power system 1, and the radial sensor collects the radial gap data between the rotor 12 and the stator 13.

[0060] First, the environmental simulation unit 3 does not provide any working conditions for the test. During the entire process from starting to stopping of the magnetic suspension rotor power system 1, the axial clearance data and the radial clearance data are collected by the axial clearance sensor and the radial clearance sensor respectively.

[0061] Secondly, the environmental simulation unit 3 provides the wind speed for the test, forms wind force in the axial, radial and lateral directions of the magnetic levitation rotor power system 1, and collects axial gap data and radial gap data respectively through the axial gap sensor and the radial gap sensor; since each sensor is respectively connected to the test control unit 4 with electrical signals, the data collected by the sensor can be transmitted to the test control unit 4.

[0062] By comparing the gap data in the two test experiments, the suspension stability performance of the magnetic levitation rotor power system 1 under the condition of external wind changes can be evaluated.

[0063] In order to determine the flight attitude of the magnetically suspended rotor power system 1, Figure 1-3 As shown in the preferred embodiment, the sensor unit 5 also includes: a single-axis inclination sensor 51, which is installed on the test bench unit 2, and collects the inclination angle data of the magnetic levitation rotor power system 1; wherein the single-axis inclination sensor 51 is electrically connected to the test control unit 4.

[0064] The sensor unit 5 in this embodiment includes a single-axis tilt sensor 51, which is installed on the test bench unit 2. The single-axis tilt sensor 51 collects the tilt angle data of the magnetic levitation rotor power system 1 (i.e., the tilt angle of the magnetic levitation rotor power system 1 relative to the horizontal plane). At the same time, since the single-axis tilt sensor 51 is connected to the test control unit 4 by electrical signals, the data collected by the single-axis tilt sensor 51 can be transmitted to the test control unit 4. By collecting the tilt angle data of the magnetic levitation rotor power system 1, the flight attitude of the magnetic levitation rotor power system 1 can be determined (the flight attitude refers to the tilt state of the magnetic levitation rotor power system 1 relative to the horizontal plane when it is working).

[0065] In order to determine the motor temperature of the magnetic levitation rotor power system 1, in this embodiment, the sensor unit 5 preferably also includes: a temperature sensor 57, which is installed on the motor of the magnetic levitation rotor power system 1, and the temperature sensor 57 collects temperature data of the motor drive coil 17 of the magnetic levitation rotor power system 1; wherein the temperature sensor 57 is electrically connected to the test control unit 4.

[0066] The sensor unit 5 in this embodiment includes a temperature sensor 57, which is installed on the motor of the magnetic levitation rotor power system 1. The temperature sensor 57 collects temperature data of the motor drive coil 17 of the magnetic levitation rotor power system 1. At the same time, since the temperature sensor 57 is electrically connected to the test control unit 4, the data collected by the temperature sensor 57 can be transmitted to the test control unit 4. The difference obtained by comparing the data collected by the temperature sensor 57 with the ambient temperature during the test is the temperature rise data of the motor drive coil 17, and the motor status is monitored through the temperature rise data.

[0067] By collecting the temperature data of the motor of the magnetic levitation rotor power system 1, it is possible to determine whether the working temperature of the motor of the magnetic levitation rotor power system 1 is maintained below 75 degrees Celsius, thereby ensuring the safety of the motor operation.

[0068] In order to simulate various test environments of the magnetic levitation rotor power system 1 during the test, such as Figure 2 and Figure 3 As shown, in the present embodiment, the environment simulation unit 3 preferably includes: an air blower assembly, which is arranged toward the test bench unit 2, and the air blower assembly performs a blowing action toward the test bench unit 2; a spray assembly, which is arranged toward the test bench unit 2, and the spray assembly performs a spraying action toward the test bench unit 2; an angle tilting assembly 31, which is rotatably mounted on the mounting portion 23, and the angle tilting assembly 31 drives the mounting portion 23 to rotate.

[0069] In this embodiment, the environmental simulation unit 3 composed of a blowing component, a spray component and an angle tilting component 31 is used. First, the blowing component is set toward the test bench unit 2 and a blowing action is performed toward the test bench unit 2. By implementing the blowing action, the working condition of the magnetic levitation rotor power system 1 encountering an external environment with different wind speeds can be simulated; secondly, the spray component is set toward the test bench unit 2 and a spraying action is performed toward the test bench unit 2. By implementing the spraying action, the working condition of the magnetic levitation rotor power system 1 encountering different external environments with water can be simulated. Finally, the angle tilting component 31 is rotatably connected to the mounting part 23 and drives the mounting part 23 to rotate. By rotating the mounting part 23, the working condition of the magnetic levitation rotor power system 1 in different flight attitudes can be simulated. Therefore, through the cooperation of the above-mentioned components, various test environments (such as flight attitude, wind speed, rainfall, etc.) during the test of the magnetic levitation rotor power system 1 can be simulated.

[0070] The specific process of the performance test system test of the magnetic levitation rotor power system in this embodiment is as follows:

[0071] 1. Power performance. The force sensor 52 measures the actual lift of the magnetic levitation rotor power system 1 and outputs a voltage signal. The voltage signal is input into the force sensor acquisition module, and the analog signal is converted into a digital signal, which is transmitted to the test control unit 4 through the RS-485 serial interface. The power performance is evaluated by the actual lift and lift-torque ratio under different working conditions. The lift size is measured by the force sensor 52, and the lift-torque ratio is the ratio of the actual lift to the actual torque. The greater the lift, the greater the lift-torque ratio, and the better the power performance.

[0072] 2. Suspension stability performance is evaluated based on the output stability of the suspension force and the stability of the gap change. During the entire process from starting to stopping the magnetic levitation rotor power system 1, first, no test conditions are added (that is, the environmental simulation unit 3 does not provide any working conditions), and the suspension stability is tested. The gap (voltage signal) measured by the gap sensor 56 built into the magnetic levitation rotor power system 1 is used to analyze the spatial posture of the rotor 12. Add a wind test, and use the environmental simulation unit 3 to generate additional wind in the axial, radial, and axial lateral directions of the magnetic levitation rotor power system 1, analyze the gap data, and evaluate the control stability of the magnetic levitation rotor power system 1 under external wind changes. The axial gap data and radial gap data collected by the gap sensor 56 are converted into digital signals through an A / D converter and transmitted to the test control unit 4 through the RS-485 serial interface.

[0073] 3. The driving control performance is mainly evaluated from the actual lift, torque and speed. The speed sensor 53 measures the speed data of the motor of the magnetic levitation rotor power system 1. The output pulse signal is input into the speed sensor acquisition module, and the pulse signal is converted into a digital signal, which is transmitted to the test control unit 4 through the RS-485 serial interface. The test control unit 4 is arranged with a voltage sensor 54 and a current sensor 55. The current sensor 55 measures the actual current value of the motor drive coil 17, the axial suspension coil 15 and the radial suspension coil 18. The voltage sensor 54 measures the actual voltage of the motor drive coil 17, the axial suspension coil 15 and the radial suspension coil 18. The data collected by the sensors are converted into digital signals through an A / D converter and transmitted to the test control unit 4 through the RS-485 serial interface. The actual torque is calculated based on the actually measured lift and speed data and the voltage and current data of the motor, and compared with the torque calculated by the motor mathematical model evaluation. At the same time, the fluctuation of the output torque is analyzed to verify whether the control effect of the drive motor meets the requirements.

[0074] 4. Waterproof performance. The environmental simulation unit 3 can provide water scenarios of different levels, such as a small amount of water, local splashing water, all-directional splashing water, local spraying water, and all-directional spraying water. The magnetic levitation rotor power system 1 will be exposed to water environments of different degrees (spraying water, splashing water, etc.) to test its water protection effect.

[0081] S4, the magnetic suspension rotor power system 1 receives the control signal and performs corresponding regulation;

[0082] Specifically, the control specifically refers to that after the magnetic levitation rotor power system 1 receives the control signal, the current passing through the axial suspension coil 15, the motor drive coil 17, and the radial suspension coil 18 is controlled, thereby controlling the motor speed, axial clearance, radial clearance, etc. of the magnetic levitation rotor power system 1;

[0083] S5, the sensor unit 5 receives the control signal and collects data of the magnetic suspension rotor power system 1 under various working conditions;

[0084] S6 , the test control unit 4 receives the data collected by the sensor unit 5 .

[0085] Furthermore, the sensor unit collects data of the magnetic levitation rotor power system 1 under various working conditions, including: the lift of the magnetic levitation rotor power system 1, the speed of the motor of the magnetic levitation rotor power system 1, the current of the motor drive coil 17 of the magnetic levitation rotor power system 1, the voltage of the motor drive coil 17 of the magnetic levitation rotor power system 1, the axial gap between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1, and the radial gap between the rotor 12 and the stator 13 of the magnetic levitation rotor power system 1.
