Description

Technical Field

[0001] The present invention relates to the technical field related to impact tests, and in particular to a high-frequency reciprocating motion control valve. Background Art

[0002] Impact test is generally a test method to determine the safety, reliability and effectiveness of military and civilian equipment when subjected to external impact or action. The impact test bench is mainly used for mechanical environmental testing of products and can simulate actual impact pulses and impact energy. In the current impact test specifications, one is to specify impact motion (such as half-sine pulse, post-peak sawtooth pulse, etc.) and its tolerance requirements, and the other is the impact response spectrum specification, which describes the damage caused by impact motion to the system. The object of concern is not the impact waveform itself that causes this response, but the effect of the impact on the structure, equipment or system. At present, most impact test equipment is implemented using a free-fall impact tester. For impact tests of certain specimens, horizontal impact must be used.

[0003] At present, there are roughly two types of horizontal impact test benches. One is the imported horizontal impact test bench, which uses the deformation energy of the elastic rope as the power (such as the horizontal impact test bench of MTS company) to generate the required initial impact velocity, but it occupies a large area and has high maintenance costs. The other is the horizontal impact test bench using a reciprocating cylinder. Since it cannot control the intake and exhaust of the cylinder at high speed and high frequency, the reciprocating cylinder cannot have regular intake and exhaust, resulting in low accuracy and low efficiency, which affects the normal operation of the horizontal impact test bench and needs to be improved. Summary of the invention

[0004] The object of the present invention is to provide a high-frequency reciprocating motion control valve to solve the problem mentioned in the above background technology that in the horizontal impact test, the intake and exhaust of the cylinder cannot be controlled at high speed and high frequency, so that the reciprocating cylinder cannot have regular intake and exhaust, resulting in low precision and low efficiency, affecting the normal operation of the horizontal impact test bench.

[0006] Preferably, the No. 1 pressure ring controlled air inlet and the No. 2 pressure ring controlled air inlet are connected to the interior of the support through the pressure rings respectively.

[0007] Preferably, the rotating intake and exhaust distribution wheel is provided with four groups of intake and exhaust ports, and the intake and exhaust ports of the rotating intake and exhaust distribution wheel are evenly distributed on the rotating intake and exhaust distribution wheel.

[0008] Preferably, the fixed intake and exhaust distribution wheel air inlets and the fixed intake and exhaust distribution wheel exhaust outlets are each provided with four groups, and the fixed intake and exhaust distribution wheel air inlets and the fixed intake and exhaust distribution wheel exhaust outlets are arranged in a staggered manner.

[0009] Preferably, the aperture size of the inlet and exhaust port of the rotating inlet and exhaust distribution wheel is the same as that of the inlet and exhaust port of the fixed inlet and exhaust distribution wheel and the exhaust port of the fixed inlet and exhaust distribution wheel and they are symmetrically arranged.

[0010] Preferably, an exhaust hole is provided on one side of the support, and the exhaust hole is connected to the interior of the support through a fixed air intake and exhaust distribution wheel.
