Abstract

The piston's movement differential equations were built based on the analyzation of the working principles of reverse countboring pneumatic impactor as well as kinematics and dynamics of the piston. Analyzed the change rule of three air chambers' volume and pressure of impactor in the working process. Volume and pressure change equations of three air chambers and flow equations of gaseous mass exchange among the three chamber were built during different moving stages of the piston. Based on the above study, set up mathematical model and simulation method of the working process of reverse counterboring pneumatic impactor. Study theoretical relationship between performance parameters and structure parameters of impactor. Based on this, establish optimization design method of impactor providing theoretical support for the application of reverse counterboring pneumatic impactor.
