摘　　要：从基础和设备间的接触力特点出发,采用Matlab/SIMULINK仿真软件建立了爆炸地冲击作用下浮放设备的滑移抛离模型,并验证了该模型的正确性。通过输入实测爆炸地冲击加速度波得出在真实爆炸环境中浮放设备的运动历程可分为相对静止、滑移、抛离、滑移减速等四个阶段。并根据其特点,提出了合理简化加速度波,采用该加速度波形,分析得到了浮放设备运动响应与动摩擦系数、爆炸地运动参数的关系。Based on the contact force characteristics in the interface between the free-standing equipment and base, a sliding-kicking up model for free-standing equipment under explosion seism impact is proposed by Matlab/SIMULINK software, and its correctness is verified. The dynamics equations and the critical conditions of different motion states are solved out. The motion process of the freestanding equipment in the real explosion environemnt can be divided into four stages including conglutination, sliding, free flight, hard stops by inputting the real explosion acceleration wave to this model. A reasonable simplified acceleration is developed, and by which variation of the motion response of the free-standing equipment with the kinetic friction coefficient and explosion seism parameters is obtained.
