摘要
阐述了凸轮式跌落冲击台的结构原理、力学性质、冲击参数与其调整方法。凸轮式跌落冲击台产生的次冲击能够影响试件的测试参数并能引起试件的疲劳损伤，说明了消除次冲击的方法。
The Construction principle, mechanical properties, basic shock parameters and adjustment methods of cam-type drop -test shock machine are described. The secondary shock acceleration pulse which are produced by the drop-test can influence the testing parameters and caues the fatigue and damage for components. The method for eliminating the secondary shock acceleration pulse is also introduced.
