【摘要】 基于虚拟样机技术,利用SimulationX软件对应用于RPH系列双向气动冲击矛的正反气动冲击机构建立了系统仿真模型,在模型上进行了一系列的仿真模拟,得到了冲击机构工作参数的变化过程,比如活塞的冲击速度曲线、冲击力曲线等,揭示了其内部结构的工作状态。通过仿真模拟分析,找到了影响冲击机构性能的主要结构参数。通过一组模拟,选取了影响冲击机构性能的主要参数的最恰当值,对设计进行了优化。更多还原

【Abstract】 Based on the virtual prototype technology,a system simulation model of the reversible pneumatic impact mechanism applied in RPH serial reversible pneumatic hammer was established by using the software SimulationX.A series of simulations were carried out.The change process of the impact mechanism in detail was obtained,curve of impact velocity of piston,curve of impact force(e.g.),and the working status of the internal structure of the RPH serial reversible pneumatic hammer were revealed.Then,by simulation analysis,the main structural parameter which influences the mechanism performance most was found.Finally,through a group of simulations,the most appropriate value of the parameter which influences the mechanism performance most was selected,and the design was optimized.更多还原
