分析了目前常用的机械撞击式响应谱试验机的特点和存在的一些问题，设计了一种以压缩空气作为锤头动力的新型气动式冲击响应谱试验机，给出了锤头速度计算公式和响应谱最大值的估算方法，为大型产品的冲击响应谱试验提供了一种手段。 In this paper, the character and weakness of mechanical shock response spectrum testing machine have been analyzed. A new pneumatic impact response spectrum testing machine using the compressed air as the pendulum power is designed. Also, the computational formula of pendulum velocity and the estimation method of the maximum value of SRS are introduced, which provides a method for large products＇ SRS test.
