摘要
Abstract
Based on the finite element method,the structural finite element method of front door of some cars was established and the modal analysis was done under the condition of free unconstrained load.In different working condition of opening angle of front door,the vertical stiffness was analyzed according to the deformation of front door;the analysis of lateral stiffness for structure of front door was done under the loading status at different position.The simulation and solution of finite element was proceeded by HyperMesh and Altair optistruct,which can provide theoretical basis for the evaluation of natural frequency and vibration model of front door and the design and optimization of product structure,having a certain value on theory and engineering application.关键词
