本文用声学理论和振动力学方程的推导来阐述声波在试验夹具中的传播特性,并用具体的试验加以验证说明,从而指出在试验夹具设计时不可忽略声波对其的影响。
In this paper, the propagation characteristics of sound waves in the test fixture are explained by the derivation of acoustic theory and vibration mechanics equations, and verified by concrete tests. It is pointed out that the influence of sound waves on the test fixture design should not be neglected.
