摘　　要：火箭炮闭锁力是阻止火箭弹脱落和影响火箭弹发射的重要参数。考虑到目前对于闭锁力特性研究较少,有必要对闭锁机构进行研究。基于理论力学推导出闭锁力的计算公式和临界位置的平衡方程,求解出闭锁力在不同闭锁体倾斜角和摩擦系数时变化曲线,并采用软件仿真和试验实测进行分析。通过理论计算、仿真计算和试验测试互相验证,给出了一套完善的闭锁机构设计方法,为火箭炮闭锁机构设计提供参考。The locking force of rocket artillery is an important parameter which prevents the rocker from falling off and influences the rocket launching. In view of the current research on the characteristics of the locking force less, it is necessary to study the locking mechanism. Based on the theoretical mechanics, the calculation formula of the locking force and the equilibrium equation of the critical position are de- duced, and the locking force variation curve of the differential angle of locking body and friction coefficient is solved, which is verified using software emulation and experimental measurement. Through theoretical calculations, simulation and experimental to verify each oth- er, the design method of the locking mechanism is given, which can provide reference for the design of the lock mechanism.
