| Abstract: | Open and close operation of one certain car's trunk lid system is simulated dynamically with LS-DY-NA3D software in this paper.The dynamic simulation is done on the basis of interactive relations between trunk lid,hinges,lock,sealing strips and vehicle body.Force curves of various moving parts and stress distribution of various compo-nents are obtained by the simulation,then fatigue strength of the system are analyzed.Finally,improving measures are presented to improve design quality and life cycle. |
