[0034] Working principle:

[0035] Example 1

[0036] When the parts under inspection inside the basket 3 need to maintain a small-amplitude vibration state during the experiment, place the parts under inspection on the top surface of the material loading plate 5, and then close the sealed box door 2 and start each system inside the test chamber main body 1 to conduct an ice-water impact test on the parts under inspection inside the basket 3;

[0037] During the ice-water impact test, start the water pump 8. The water pump 8 transports the water in the immersion water tank 12 to the inside of the support sleeve 111 through the transition pipe. Then, under the continuous water pressure, the inverted T-shaped piston rod 112 is lifted to press the material loading plate 5. When the bottom structure of the inverted T-shaped piston rod 112 moves above the lowermost pressure relief hole on the support sleeve 111, the inverted T-shaped piston rod 112 stops moving. Then, turn off the water pump 8. The material loading plate 5 and the inverted T-shaped piston rod 112 will move back under the restoring elastic force of the spring 6. Thus, reciprocatingly, the parts placed on the top of the material loading plate 5 undergo small-amplitude vibrations to participate in the ice-water impact test, improving the test data.

[0038] Example 2

[0039] When the parts under inspection inside the basket 3 need to maintain a large-amplitude vibration state during the experiment, place the parts under inspection on the top surface of the material loading plate 5, and then close the sealed box door 2 and start each system inside the test chamber main body 1 to conduct an ice-water impact test on the parts under inspection inside the basket 3;

[0040] During the ice-water impact test, first turn off the electric push rod inside the displacement power component 9 that is in the open state. Then, the output end of the electric push rod drives a second meshing rod 104 to move synchronously. Under the meshing drive of the transmission gear 101, the other second meshing rod 104 will move synchronously in the opposite direction until it reaches the lowermost pressure relief hole on the sleeved support sleeve 111, giving way to the upper pressure relief hole;

[0041] Start the water pump 8. The water pump 8 transports the water in the immersion water tank 12 to the inside of the support sleeve 111 through the transition pipe. Then, under the continuous water pressure, the inverted T-shaped piston rod 112 is lifted to press the material loading plate 5. When the bottom structure of the inverted T-shaped piston rod 112 moves above the uppermost pressure relief hole on the support sleeve 111, the inverted T-shaped piston rod 112 stops moving. Then, turn off the water pump 8. The material loading plate 5 and the inverted T-shaped piston rod 112 will move back under the restoring elastic force of the spring 6. Thus, reciprocatingly, the parts placed on the top of the material loading plate 5 undergo large-amplitude vibrations to participate in the ice-water impact test, improving the test data.
