基于FEM的汽车加速踏板臂断口槽优化设计
Optimization design of fracture groove for automobile accelerator pedal arm based on FEM
摘要
Abstract
Aiming at the problem of building a fracture groove on an automobile accelerator pedal arm, a method based on finite element method ( FEM ) is put forward to determine the fracture groove’s position,shape,size and other parameters. A pedal arm without fracture groove is analyzed by using the FEM,and the exact location of the maximum stress on the pedal arm is found. The fracture grooves with different parameters are built in the product model,the suitable shape and size of the fracture groove is determined by comparison. According to the given parameters,a sample piece is produced and experimentally verified. The analysis and experiments show that building a fracture groove of suitable shape and size in the maximum stress location of the pedal arm can meet the practical requirement and specific safety codes.关键词
