Mechanical Performance Evaluation and Structural Optimization of Automobile Front-end Frame
new material replacement and structural optimization are adopted to optimize the design of a front-end framework in order to meet the requirement of lightweight and safety of automotive components.The plastic front-end frame made of long glass fiber reinforced polypropylene material is proposed.Mechanical properties of front-end frame such as stiffness,strength and Modal are evaluated with Computer Analysis Engineering(CAE)and stiffness weakness of overall structure is identified with corporate standard.The stiffness indicator of the front-end frame is enhanced by means of optimizing reinforcing rib shape and wall thickness of the locking zone.The result shows that the stiffness along X and Z direction of the locking zone increases by 20.4％o and 42.1％re-spectively.The optimized model can be manufactured into solid product through injection molding process.The CAE performance evaluation and optimization method provided in this article can be applied to improve the effi-ciency of product development.
