摘　　要：时变质量系统的运动是指在经典力学的研究领域中,运动系统的质量随着时间的变化而发生有规律或随机的变化.本文基于时变质量系统运动的理论,建立了撇缆器弹体运动的动力学模型,并对撇缆器弹体运动进行模拟仿真.在此基础之上设计了验证实验,验证了时变质量系统动力学模型的正确性.The movement of time-varying mass system refers to the mass of system changes regularly or randomly over time in the research field of classical mechanics. In this paper,based on the theory of time-varying mass system movement,we build a dynamics model of line-throwing appliance＇s projectile movement,and simulate its movement. On this foundation,we design an experiment to verify the dynamic model of the time-varying mass system.

关 键 词：时变质量系统 动力学模型 撇缆器
