DETAILED DESCRIPTION

[0031] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples of the specification. The following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] The terms such as upper, lower, left, right, inside, outside, front end, rear end, head, tail, etc. in this application document are based on the positions or positions shown in the drawings. If the drawings are different, the corresponding positions may also change accordingly, so they cannot be understood as limiting the scope of protection.

[0033] In the present invention, the terms "install", "connected", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection or mutual communication, a direct connection or an indirect connection through an intermediate medium, the internal connection of two components, or the interaction relationship between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] This embodiment records a full-speed electric drive fin stabilizer comprehensive loading test device and test method, which can effectively solve the endurance loading requirements of the full-speed electric drive fin stabilizer under full-speed conditions, and at the same time realize data monitoring and recording of the entire endurance loading process.

[0035] The comprehensive loading test device includes a loading system and a monitoring system. The loading system is used to load the full-speed electric-driven fin stabilizer under test, and the monitoring system is used to perform global and full-time monitoring and recording of the durability status of the full-speed electric-driven fin stabilizer.

[0036] like Figure 1 As shown, the loading system includes a base 1, a test bench 2, an adapter sleeve 3, a universal joint 4, a cylinder mounting stand 5, a rotary vane cylinder 6, a loading unit 8, an integrated loading controller 9, a control box 10 and a start box 11.

[0037] The base 1 is a support base of the comprehensive loading test device, which can be fixed to the test site by bolts, or can be a base directly cast on the test site.

[0038] The test bench 2 and the cylinder mounting bench 5 are respectively mounted on the base 1 by bolts. A fin mounting hole is provided on the upper part of the test bench 2 for mounting the actuator 12 of the full-speed electric drive anti-roll fin. A cylinder connecting hole coaxial with the fin mounting hole is provided on the upper part of the cylinder mounting bench 5. The vane cylinder 6 is fixed to the outer side of the cylinder mounting bench 5 by bolts, and the output end of the vane cylinder 6 is coaxial with the cylinder connecting hole. In order to adapt to the loading test of different actuators 12, multiple rows of bolt holes are provided on the base 1, and the test bench 2 and the cylinder mounting bench 5 are fixed by bolts through the corresponding bolt holes according to the size of the actuator 12.

[0039] The fin shaft of the actuator 12 of the full-speed electric-driven anti-roll fin to be tested passes through the fin mounting hole and extends to the vane cylinder 6 on the cylinder mounting stand 5, and the actuator 12 is fixed to the test stand 2 by bolts.

[0040] The adapter sleeve 3 is installed at the output end of the fin shaft, and both ends of the adapter sleeve 3 are flange ends. The fin shaft of the actuator 12 is a tapered shaft. The output interface of the actuator 12 can be changed from a tapered shaft to a flange through the adapter sleeve 3, which not only ensures the stability of the test, but also can realize the comprehensive loading test of the electric-driven anti-roll fin actuator 12 of different specifications at full speed by replacing the adapter sleeves 3 of different specifications, thereby expanding the applicability of the comprehensive loading test device. The adapter sleeve 3 is connected to the blade cylinder 6 through the universal coupling 4, and torque is transmitted between the actuator 12 and the blade cylinder 6. The universal coupling 4 of this embodiment is the largest model coupling suitable for the test device, so that the actuators 12 of different specifications can be connected to the universal coupling 4 through the corresponding adapter sleeve 3. Preferably, the rotation angle of the blade cylinder 6 is not less than 120 degrees to meet the loading test of the electric-driven anti-roll fin at full speed.

[0041] The oil inlet and outlet of the blade-turning cylinder 6 are connected to the loading unit 8 through hydraulic hoses respectively. The integrated loading controller 9 controls the high-pressure oil of the loading unit 8 to adjust the load pressure of the blade-turning cylinder 6 in real time according to the operating parameters of the full-speed electric-driven anti-roll fin to realize loading simulation.

[0042] Specifically, the integrated loading controller 9 of this embodiment is respectively connected to the loading unit 8 and the control box 10 by data (can be connected by wires or wirelessly), and the control box 10 is used to collect the fin angle, angular acceleration, and fin angular velocity signals monitored in real time by the servo motor encoder of the actuator 12, and transmit the fin command, fin angle, and fin angular velocity signals to the integrated loading controller 9. The integrated loading controller 9 displays and records the fin command, fin angle, and fin angular velocity signals in real time, and calculates the set pressure in combination with the oil inlet and outlet pressures of the vane cylinder 6 collected by the monitoring system, and sends the set pressure to the loading unit 8, and the loading unit 8 loads the vane cylinder 6 according to the set pressure.

[0043] The start box 11 is data-connected with the control box 10 and the actuator 12. The control box 10 sends a fin rotation instruction (the fin rotation instruction is a sinusoidal periodic signal of fin rotation generated by the control box 10 through the period and amplitude parameters of the sine given by the operator. Generally, the period can be the rolling period of the applied ship, and the amplitude can be the maximum fin rotation angle of the anti-roll fin) to the start box 11. The start box 11 receives the fin rotation instruction issued by the control box 10 to control the actuator 12 to perform the fin rotation action.

[0044] like Figure 1 As shown, the monitoring system includes a pressure sensor 7, a temperature sensor 13, a vibration sensor 14 and a noise sensor. The integrated loading controller 9 is data-connected with the pressure sensor 7, the temperature sensor 13, the vibration sensor 14 and the noise sensor respectively.

[0045] Pressure sensors 7 are installed at the oil inlet and outlet of the vane turning cylinder 6 to measure the pressure of the oil inlet and outlet of the vane turning cylinder 6 and transmit the pressure signals of the oil inlet and outlet to the integrated loading controller 9. The integrated loading controller 9 monitors the pressure of the oil inlet and outlet of the vane turning cylinder 6 in real time to know the real-time torque of the vane turning cylinder 6, so as to compensate the set pressure in real time to ensure that the vane turning cylinder 6 is loaded according to the set pressure.

[0046] The temperature sensor 13 is installed on the actuator 12 and is used to collect the temperature signal of the actuator 12 and send the temperature signal to the integrated loading controller 9 .

[0047] The vibration sensor 14 is installed on the test bench 2 to collect vibration signals and send the vibration signals to the integrated loading controller 9 .

[0048] The noise sensor is arranged at a predetermined position on one side of the test bench 2 (eg, 1 meter away from the test bench 2 ), collects the test noise, and sends the noise signal to the integrated loading controller 9 .

[0049] The integrated loading controller 9 receives the pressure signal, temperature signal, vibration signal, and noise signal transmitted by the pressure sensor 7, the temperature sensor 13, the vibration sensor 14, and the noise sensor, respectively, and adjusts the set pressure in real time through the pressure signal to ensure the load of the blade-turning cylinder 6. The state of the full-speed electric-driven fin stabilizer actuator 12 under test is preliminarily determined through the temperature signal and the vibration signal. When the temperature signal or the vibration signal exceeds the set threshold, an alarm is issued and the test is automatically suspended. The state of the full-speed electric-driven fin stabilizer actuator 12 and the integrated loading test device is preliminarily determined through the noise signal. If there is abnormal noise, an alarm is issued and the test is automatically suspended to ensure the safety of equipment and personnel. While displaying in real time, the integrated loading controller 9 monitors and records the durability state of the full-speed electric-driven fin stabilizer in a global and full-time manner.

[0050] The comprehensive loading test device of this embodiment applies a load adapted to the working conditions during the full-speed electric drive fin stabilizer durability process to conduct a loading test, and the process is as follows:

[0053] 2. The control box 10 sends a fin rotation instruction to the start box 11. The driver in the start box 11 drives the actuator 12 to perform the fin rotation action according to the fin rotation instruction, and the adapter sleeve 3 and the universal joint 4 transmit the rotation motion of the actuator 12 to the vane cylinder 6. At the same time, the pressure sensor 7, the temperature sensor 13, the vibration sensor 14 and the noise sensor respectively collect and receive the pressure signal, the temperature signal, the vibration signal and the noise signal, and transmit them to the integrated loading controller 9 respectively;

[0054] The control box 10 sends the fin turning instruction, the collected fin turning speed, and the fin turning angular velocity to the integrated loading controller 9 at the same time. The integrated loading controller 9 switches the loading mode to the zero speed loading mode or the normal speed loading mode according to the received fin turning instruction, sets the pressure according to the fin turning speed, the fin turning angular velocity, and the pressure signal analysis collected by the monitoring system, and outputs the corresponding set pressure to the loading unit 8. The loading unit 8 applies pressure to the blade turning cylinder 6 according to the set pressure to change the inlet and outlet pressures of the blade turning cylinder 6 to form a load, thereby realizing the simulated loading of the full-speed electric-driven anti-roll fin;

[0055] The integrated loading controller 9 calculates the set pressure P according to the following formula:

[0056] Zero speed loading mode:

[0057] Conventional speed loading mode:

[0058] In the above two formulas, α is the fin angle; ω is the fin angular velocity; is the angular acceleration; ρ is the seawater density; V is the water velocity; A is the fin area; b is the average chord length of the fin; C is the fin torque coefficient; l is the zero speed torque coefficient about angular acceleration; k is the zero speed torque coefficient about angular velocity; α0 is the full fin angle; P0 is the torque generated by the rotor cylinder per MPa.

[0059] 3. The integrated loading controller 9 receives information such as pressure signals, temperature signals, vibration signals, and noise signals to monitor and record the durability status of the electric-driven fin stabilizer at full speed in a global and full-time manner until the integrated loading test device stops after completing the test according to the test requirements; during the test, the integrated loading controller 9 preliminarily determines the state of the tested actuator 12 through the temperature signal and vibration signal, and issues an alarm and automatically suspends the test when the temperature signal, vibration signal, or noise signal exceeds the set threshold. The integrated loading controller 9 preliminarily determines the state of the actuator 12 and the integrated loading test device through the noise signal, and issues an alarm and automatically suspends the test when the noise signal exceeds the set threshold.
