| Abstract: | Based on flexible multibody dynamics,a dynamic modeling method on multibody systems with changing topologies is proposed.Classified the system constraints as basic constraints and variable constraints,the compatibility condition and the model of joint friction are studied.And then the dynamic model and the simulation analysis are given on the launching process during the missile flying away from the barrel in mobile missile system.The results of the research can be used in analysis and design of mobile missile systems. |
