本文把一类气动微震机构工作过程，抽象为一个二阶动力系统。对其运动 过程进行动力学分析。文中采用了“后继点”方法，使人们易于了解系统震击 的过渡过程，根据工程技术对震击过程的要求，推出了有关选择系统参数的计 算公式，并给出一种震击周期（或频率）的计算方法。 In this paper, the working process of a kind of pneumatic microseismic mechanism is abstracted as a second-order dynamic system. Dynamic analysis of its movement process. In this paper, the “successor point” method is adopted to make it easy for people to understand the transition process of system shock. According to the requirements of engineering and technology for shock process, a formula for selecting system parameters is introduced and a shock cycle (or Frequency) calculation method.
