DETAILED DESCRIPTION

[0020] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only part of, rather than all of, the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0021] With reference to Figures 1-5 The ice damage multi-physical synchronous measurement system disclosed by the embodiments of the present application comprises: a motion monitoring control system 1, a load force sensor 2 of an ice load measurement system, a laser displacement sensor 3 of a non-contact deformation measurement system, a temperature and pressure monitoring system 4, a high-speed camera 5a and a fill-in light 5b of a high-speed camera acquisition system, a multi-physical quantity measurement synchronous trigger acquisition system 6, and a multi-degree-of-freedom adaptive measurement integrated mobile platform 7. The measured object is an ice sample placed on an impact test bench 8.

[0022] The motion monitoring control system 1 comprises a servo controller 1a and an encoder 1b. When a mechanical impact action is performed, the position and torque signals of the servo motor are output to the servo controller 1a. The servo controller 1a controls the servo motor in a closed loop through feedback position and torque signals. The physical quantities such as speed, force and position output by the servo controller 1a are converted according to the lead screw pitch, speed reduction ratio and system efficiency of the electric push rod used to perform linear impact, and can be used as the speed, output force and displacement of the impact head performing mechanical impact and the motion characteristics of the mechanical structure impact.

[0023] The speed, output force and displacement can be determined according to the motor speed, lead screw pitch and speed reduction ratio to determine the execution speed.

[0024] In the formula, V represents the execution speed, and the unit is mm / s. V m : Servo motor speed, unit rpm L: Lead screw pitch, unit mm R: Speed reduction ratio

[0025] In addition, the motor feedback torque can be converted into the output force size.

[0026] In the formula, F represents the output force of the electric cylinder performing mechanical impact, and the unit is kN. T: Servo motor output torque, unit N·m N: Output efficiency after removing system loss

[0027] There is an absolute conversion relationship between the servo motor's rotational position and speed and its linear motion displacement and speed. However, there are system losses between the servo motor's torque and linear thrust, which need to be compensated by combining the ice load measurement system 2.

[0028] The load force sensor 2 of the ice load measurement system is mounted on an electric actuator that extends into the submersion chamber. The lower part of the load force sensor 2 is connected to the electric actuator, and the upper part has a transition joint connecting it to the impact head. Specifically, the load force sensor 2 is a high-frequency response tensile / compressive sensor with its own temperature drift adaptive correction function. The signal line of the load force sensor 2 has good sealing properties, enabling it to adapt to the temperature variations of underwater submersion. The load force sensor 2 is installed between the electric actuator and the impact head, and based on Newton's third law, measures the time-history load during the mechanical impact process, especially the ultimate peak load, as one of the important quantitative indicators.

[0029] Simultaneously, load sensor 2 is also used for calibrating the output efficiency of the motion monitoring and control system. The linear motion process of underwater submerged ice damage involves various additional resistances, leading to errors between the actual and theoretical linear output forces. These include the flow resistance of the submerged water and frictional resistance related to rotational inertia and damping within the system. Failure to reach the preset linear output force results in a weakening of the system's ultimate stiffness under uniform impact. By utilizing load sensor 2 in the ice load measurement system, system errors can be calibrated under the same experimental conditions, and output compensation can be provided to the motion monitoring and control system.

[0030] The non-contact deformation measurement system consists of an array of at least four laser displacement sensors, such as... Figure 3 and Figure 5 As shown, the laser displacement sensor 3 is mounted on the laser displacement sensor bracket 7c on the multi-degree-of-freedom adaptive measurement integrated mobile platform 7. Its laser path is vertically downwards directed towards typical monitoring points on the ice material. The range of the laser displacement sensor 3 is no less than 200–1200 mm. Because the ice material is nearly transparent, the laser displacement sensor 3 has high requirements for reflection; therefore, laser reflection stickers need to be affixed to typical characteristic locations on the upper surface of the ice. Furthermore, the impact damage process is very brief, and the vertical deformation of the surface changes rapidly. The response frequency of the laser displacement sensor 3 should be no less than 10 kHz. The vertical deformation measurement results at typical locations can be directly used as quantitative data for numerical simulation verification.

[0031] This process uses non-contact measurement to obtain clear images of ice material damage and crack evolution. Compared with conventional ice material deformation and displacement measurement, it avoids the original damage caused by contact measurement intrusion into the ice material, thus achieving the effect of non-destructive testing.

[0032] A temperature sensor 4a is arranged in the submerged cavity of the impact test bench 8, and a temperature sensor 4a and a pressure sensor 4b are arranged in the jet pipeline to form a temperature and pressure measurement system 4. The temperature sensor 4a in the submerged cavity is used to monitor the temperature of the water environment in the submerged cavity, and the temperature sensor 4a and the pressure sensor 4b in the jet pipeline are used to monitor the jet water temperature and the jet pressure.

[0033] Since the ice material is sensitive to temperature, the water temperature under the ice is one of the important physical quantities that need to be controlled during the ice damage test process. The temperature sensor 4a used has a range of at least -20℃ to 80℃ and a response frequency of not less than 1Hz. The jet pressure is a direct manifestation of the jet intensity. The pressure sensor 4b used has a range of not less than 0 to 40MPa and a response frequency of not less than 1kHz. The measurement heads of the temperature sensor 4a and the pressure sensor 4b in the jet pipeline are externally threaded and are connected to the inner threads on the wall of the jet pipeline. In this way, the initial parameters such as temperature and pressure can be accurately controlled, which is of great significance to the rigor and scientific nature of the test.

[0034] The high-speed camera 5a of the high-speed camera system is located above the non-contact deformation measurement system, as shown in Figure 3 、 Figure 4 and Figure 5 . The laser displacement sensor 3 does not hinder the imaging light path of the high-speed camera 5a. The high-speed camera 5a is suspended on two movable long beams 7a and one movable short beam 7b. The movable long beam 7a and the movable short beam 7b can drive the high-speed camera 5a to translate arbitrarily in the horizontal plane, which is used for fine adjustment of the shooting position. In the vertical direction, the depth of field can be adjusted by adjusting the focal length of the lens, so that the entire picture can be captured. The high-speed camera 5a is a back-illuminated CMOS ultra-high-speed camera with a resolution of 1280×800 and a frame rate of not less than 50,000 frames per second. It can capture the transient process of ice body fracture, and the crack propagation speed can be calculated after subsequent proportional calibration. The fill light 5b is a non-flickering adjustable light source, which is placed on the side column of the multi-degree-of-freedom adaptive measurement integrated moving platform 7. The light source penetrates through the transparent acrylic glass on the side of the impact test bench 8 into the submerged water body, serving as a supplementary backlight source.

[0035] As shown in Figure 2 , the multi-physical quantity measurement synchronous trigger acquisition system 6 includes a data acquisition case 6a, a voltage signal data acquisition card 6b, a current signal data acquisition card 6c, a voltage output module 6d, a computer 6e, and a mobile storage medium 6f.

[0036] The load force sensor 1 is connected to the voltage signal data acquisition card 6b through a voltage signal amplifier 6g; The array of laser displacement sensors 2 is also connected to the voltage signal data acquisition card 6b; Temperature sensor 4a and pressure sensor 4b in temperature and pressure monitoring system 4 are connected to current signal data acquisition card 6c; The high-speed camera 3a communicates with the computer 6e on the one hand, and the computer 6e transmits a trigger high-level signal to the high-speed camera 3a synchronously through the control voltage output module 6d on the other hand. Servo driver 5a receives signals from encoder 5b and connects directly to computer 6e; Voltage signal data acquisition card 6b, voltage signal data acquisition card 6c and voltage output module 6d are connected to data acquisition chassis 6a and connected to computer 6e. The acquired data is saved to mobile storage medium 6f.

[0037] Specifically, for effective data comparison of the simulation model, effective physical isolation of data transmission lines and synchronous triggering is required to improve the signal-to-noise ratio of the acquired data and the reliability of the system. However, since the ice damage test system integrates a high-power servo motor and a submerged water environment, in addition to necessary reliable grounding, the metal backplates of each system must be connected for equipotential treatment to eliminate the potential difference loop to ground and the electromagnetic interference introduced by the high-power servo motor during operation.

[0038] Furthermore, AC and DC filters of 6h are installed before and after the switching power supply of the data acquisition system to reduce power frequency signal interference; X and Y type capacitors are installed in the transmission circuit of the sensor and the data acquisition unit to reduce common-mode and differential-mode noise interference.

[0039] The multi-degree-of-freedom adaptive measurement integrated mobile platform 7 is used to mount the laser displacement sensor 3 and its bracket 7c, the high-speed camera 5a of the high-speed camera acquisition system, and the supplementary light 5b, such as... Figure 3 , Figure 4 and Figure 5 As shown. The entire assembly is made of aluminum profiles, with two one-way wheels and two universal wheels with brakes at the bottom for easy pushing and pulling, serving the functions of calibrating position and isolating and absorbing vibration during measurement. The laser displacement sensor 3 and the high-speed camera 5a are mounted on the movable long beam 7a and movable short beam 7b of the multi-degree-of-freedom movable slide rail at the top of the gantry-type measurement integrated platform, and their horizontal positions are freely adjustable; supplementary lights are mounted opposite each other on both sides of the frame, and their height is adjustable.

[0040] The implementation principle of the multi-physics synchronous measurement system for ice damage in this application embodiment is as follows: The servo driver 1a, the load force sensor 2, the laser displacement sensor 3, the high-speed camera 5a, the signal access data acquisition box 6a, the data acquisition box 6a access computer 6e, the submerged cavity of the impact test bench 8 is filled with water, the temperature sensor 4a is used to measure the environment and the jet temperature, the pressure sensor 4b is used to calibrate the jet injection pressure, the multi-degree-of-freedom adaptive measurement integrated mobile platform 7 is adjusted, the position is calibrated, the ice body is placed on the impact test bench 8, the measurement system is set to a synchronous waiting trigger state, the load between the structure and the ice, the ice body surface vertical deformation, the ice body fracture crack evolution image, the speed, the output and the displacement of the servo action and other physical quantities are recorded during the jet and mechanical cooperative destruction process, and are saved to the mobile storage medium 6f.

[0041] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
