凸轮式跌落冲击台是一种连续机械冲击装置。它在每个单次冲击过程中都产生次冲击,所以使受试产品的响应叠加,有可能造成受试产品损伤和参数超差,因此有必要消除次冲击。为此本文介绍一种消除这种冲击台次冲击的方法。一工作原理该冲击台主要由机械冲击台和电气驱动控制系统组成,如图1所示。在工作台的下面对称地安装两根导向柱并穿入铸铁机座内。在工作台下面中心位置固定一支块, Cam drop impact station is a continuous mechanical impact device. It produces a secondary impact during each single impact, so overlaying the response of the test product may result in damage to the test product and out-of-tolerance parameters, and it is therefore necessary to eliminate the secondary impact. To this end, this article describes a way to eliminate this impact on the impact of Taiwan. A working principle The impact of Taiwan mainly by the impact of Taiwan and electrical drive control system, as shown in Figure 1. Install two guide posts symmetrically under the workbench and into the cast iron housing. In the center of the table below a fixed block,
