Study on parameterized visual dynamics simulation software design

In order to solve the problem of the lack of dedicated parameterized dynamics simulation software and improve modeling efficiency and facilitate model modification in the process of design and optimization for the weapon system,such as missile launching system,multiple launch rocket system and artillery.This article studied the multibody system dynamics theory and parametric modeling software technology,a parametric multibody system dynamics simulation and analysis software for mechanical system was proposed.This software gathers modeling,solving,and visual simulation as a whole,by integrating CAD modeling method and multibody system dynamics theory,to solve the problem of bidirectional-driving parameter between CAD and CAE,to realize design parameters seamless transfer between geometric and dynamics models.The platform provides a digital tool for high-precision simulation and rapid-optimization design in each stage of mechanical system product design,such as model scheme design,optimization,adjustment,testing scheme and fault diagnosis.
