Optimization design of automotive front inner panel based on stiffness

Abstract

Taking the front cover of a certain automotive model as the research object, a new structure scheme of the front cover inner panel was proposed by carrying out the lightweight design and analysis of the front cover inner panel through material optimization and structural topology optimization based on the static stiffness and elastic deformation capacity object. The lightweight designed aluminum alloy component met the requirement of static stiffness, and the static and dynamic deformation resistance was improved while the weight reduction effect reached 36.5%.
