Application of Modeling and Simulation Analysis of Side Column Collision Conditions in Optimization of Body Structure of a MPV Model
Based on the characteristics of the body structure of a new energy MPV model,the local fine modeling is carried out.Through modeling and simulation analysis of side column collision conditions,problems such as insufficient upper end strength of the body structure,bending of the upper beam of the ceiling,large area failure of the upper welding spot of the B-column,and excessive side intrusion are found.Optimization schemes are proposed from three aspects of connection form,material selection and structural design,so as to effectively reduce the side body intrusion,improve the deformation trend of key structure of the body and reduce occupant injury.
