[0057] Figure 1 A water splash test system is described, comprising: a moving body 110, a pressure-applying assembly 130, an adjustment assembly 140, a test piece 150, a receiving assembly 160, a runway 120, and a high-speed camera. The moving body 110 drives the test piece 150 to move on the runway 120, the pressure-applying assembly 130 applies a load to the test piece 150, the adjustment assembly 140 adjusts the posture or positional relationship between the test piece 150 and the runway 120, and the receiving assembly 160 receives liquid splashed when the test piece 150 passes through the runway 120.

[0058] The moving body 110 is used to drive the test piece 150 on the runway 120 to perform the movements of an airplane taking off or landing. The moving body 110 can simulate the taxiing process of an airplane or car on the ground, and the moving body 110 can actively and freely move on various runways. The options for the moving body 110 include but are not limited to: finished vehicles, test vehicles, test benches, etc. The moving body 110 can cover speeds of 0 to 250 knots and simulate various taxiing movements according to the set path and speed, including straight driving, turning, sideslipping, drifting, and other working conditions.

[0059] like Figure 2 、 Figure 3As shown, in the embodiment of the present application, the pressure assembly 130 is fixedly connected to the moving body 110; specifically, the pressure assembly 130 includes: a slide rod 134, a platform 131 and a hydraulic cylinder 132, the slide rod 134 is fixedly connected to the moving body 110; the platform 131 is slidably connected to the slide rod 134 through a slider 133; the hydraulic cylinder 132 is fixedly connected to the slide rod 134, and the output shaft of the hydraulic cylinder 132 is fixedly connected to the platform 131. The slide rod 134 includes four, all of which are vertically fixed inside the moving body 110. A plurality of hydraulic cylinders 132 can be provided and fixedly connected to the slide rod 134. When the hydraulic cylinder 132 is started, a downward force can be applied to the platform 131, so that the test piece 150 can undergo a water splash test after bearing a certain gravity, thereby better simulating the load on the aircraft and further accurately obtaining the aircraft water splash data.

[0060] In the embodiment of the present application, the adjustment component 140 is connected to the bottom of the pressure component 130; specifically, the adjustment component 140 includes: a lateral actuator 142, the lateral actuator 142 is connected to the bottom of the platform 131; a roll actuator and a six-component force measurement system 141, the lateral actuator 142 is connected to the bottom of the platform 131; the roll actuator is connected to the lateral actuator 142; the six-component force measurement system 141 is fixedly connected to the roll actuator, and the test piece 150 is rotatably connected to the six-component force measurement system 141; wherein the lateral actuator 1 42 can be composed of a combination of a motor and a gear set, or a combination of a motor, a worm gear, a gear rack or a planetary gear. The motor drives the gear set, the worm gear, the gear rack or the planetary gear to rotate, thereby driving the test piece 150 to rotate and realize steering. The roll actuator 142 is used to adjust the deflection angle of the test piece 150 in the vertical direction, thereby simulating the water splashing situation when the aircraft deflects the wheels. The roll actuator includes a first hydraulic cylinder 143 and a second hydraulic cylinder 144, wherein the tail ends of the first hydraulic cylinder 143 and the second hydraulic cylinder 144 are The output shafts of the first hydraulic cylinder 143 and the second hydraulic cylinder 144 are fixedly connected to the bottom of the lateral actuator 142, and are rotatably connected to the six-component force measurement system 141. When the first hydraulic cylinder 143 is extended and the second hydraulic cylinder 144 remains unchanged or shortened, the test piece 150 can tilt toward the first hydraulic cylinder 143. On the contrary, when the second hydraulic cylinder 144 is extended and the first hydraulic cylinder 143 remains unchanged or shortened, the test piece 150 can tilt toward the second hydraulic cylinder 144. The cooperation of the two hydraulic cylinders realizes the tilting effect of the test piece 150. In addition to using hydraulic cylinders, pneumatic cylinders and lead screws can also achieve the same effect; the six-component force measurement system 141, also called a six-component force tester, can detect the forces acting on the test piece 150 in six directions, thereby better simulating the actual working environment and enabling the test piece 150 to obtain more accurate experimental data; the six-component force mainly refers to the forces in six directions of the Cartesian coordinate system established with the contact center between the test piece and the ground as the origin, including the three-axis corresponding three-dimensional forces (heading load, lateral load, vertical load) and three-dimensional moments (rolling moment, rolling moment, and self-aligning moment); such as Figure 10 As shown, in the Cartesian coordinate system of xyz, the orientation of the tire is the x direction, and there is an angle α between the actual speed direction of the tire and the orientation x of the tire. γ is the roll angle between the tire and the z axis. At this time, the heading load is Fx, the lateral load is Fy, the vertical load is Fz, the rolling moment is Mx, the rolling moment is My, and the self-aligning moment is Mz.

[0061] In this embodiment of the present application, a test piece 150 is movably connected to the adjustment assembly 140.

The test piece 150 is adjustable for slip angle, roll angle, pitch angle, vertical position, left-right position, and vertical load. The test piece 150 itself has no driving capability and is driven by the moving body 110. For example, a tire will passively rotate under the drive of the moving body 110 to simulate real tire conditions.

The pressure sensor is arranged on the side of the carrier facing the test piece 150. The pressure sensor is used to detect the impact force of water during the splashing process, thereby judging the water volume or impact speed according to the impact force; it can be imagined that the simulation part 161 has different combination shapes, so the simulation part 161 obtains splashing conditions from different angles according to the different simulated components.

One side faces the test piece 150. When water splashes, the water enters the slot 1621 and flows into the measuring cylinder 1623 through the drainage channel 1622. The drainage channel 1622 is inclined from the position of the slot 1621 to the position of the measuring cylinder 1623 to guide the splashed water to the measuring cylinder 1623. The measuring cylinder 1623 is provided with a scale to facilitate reading the amount of water inside. The water collection tank 162 is divided into different areas. The distribution of the water collected in different areas can be used to measure the spatial distribution of the splashing water mist. The water distribution can be used to quantitatively evaluate the impact of splashing water on equipment and structures at different locations, such as Figure 9As shown, these are the parameters of the water collected by each slot 1621 after being collected by the water collection tank 162, where 1 represents that the amount of water collected here is at most in the first gradient, 0.5 represents that the amount of water collected in this range is in the second gradient, and 0.2 represents that the amount of water collected here is in the third gradient, which is the least. Other blank spaces indicate that no splashing water is collected, or the amount of water collected fails to reach the calculated amount and can be ignored.
