摘要
提出了一种测量隔振器冲击特性的方法。通过气体炮发射的炮弹撞击砧块,使之获得一定的初速度,再 利用砧块的惯性对隔振器施加冲击载荷。使用激光位移传感器和测力钢块分别测量力和位移。从而解决了施加可控冲 击载荷和冲击条件下数据测量的问题。
A method of measuring vibration isolators shock characteristics is advanced. An anvil is impacted by the bullet from an air gun and hence a certain initial velocity is obtained. Then the vibration isolator absorbs the shock load of the anvil's inertia. The force acting on the vibration isolator and the displacement of the vibration isolator are measured with a force measuring steel block and a laser displacement sensor respectively. The problem how to act controllable shock load and how to measure the data under shock condition is thus solved.
