摘要
分析了反向扩孔气动冲击器的工作原理,建立了反向扩孔气动冲击器系统内部动力过程的的微分方程组。运用计算机仿真技术,对微分方程组进行求解,分析和研究反向扩孔气动冲击器的性能(冲击能、冲击频率、活塞行程和耗气量)与结构参数(阀孔到活塞前端距离、内活塞前端到锤头的距离)之间的相互关系。求得结构参数与性能参数相应的仿真数据与曲线。
The working principle of reverse counterboring pneumatic impactor was analyzed,and establish the differential equations of Reverse counterboring pneumatic impactor＇ s dynamic process of internal system. Using computer simulation technology to solve differential equations,analysis and research the relationship between performance parameters-impact energy,impact frequency,piston displacement and air consumption and structure parameters-the distance from valve opening to piston and from inner piston front-end to the hammer of pneumatic percussive reverse counterboring. The corresponding simulation data and curves of structure parameters and performance parameters are obtained.
