Abstract:Multi-function and practicality have attracted more attention in the research of vehicle engineering.Based on the requirements for family economic cars,more attentions are paid to the vehicle trunk transforming.Firstly,based on the regenerated movement link theory,the structure of the transformation mechanism for vehicle trunk is designed.Furthermore,in order to obtain an optimal design,a numerical simulation analysis based on aerodynamic performance is conducted,and the improvements are made with these simulation results.The results prove that the proposed mechanical structure design conforms with the requirements and completes the transformation between the forms of sedan and hatchback.The sedan has the smaller wind resistance coefficient than the hatchback,and has the advantages in aerodynamics.The study results supply theoretical support and practical basis for variable volume vehicle design.
