Optimization Design of the Structure of the Manual Swing-out Luggage Compartment Door of Passenger Cars

摘要

This study studies the design of the manual swing-out luggage compartment door of a medium-sized passenger car, which makes design process more specific and design ideas clearer. Firstly, the tumbler arm is optimized and its weight is reduced by the method of designing a four-bar linkage of luggage compartment door and dynamic and structural strength analysis of the structure of the luggage compartment door is performed. Then, parametric design of the tumbler model is carried out in order to map out different vehicle models quickly. Finally, motion and interferences analysis of the compartment door is made to avoid any potential structure intervention.
