摘要:
针对在汽车加速踏板臂上开设断口槽的问题,提出了一种基于有限元法(FEM)的断口槽位置、形状、尺寸等参数的确定方法。采用FEM,对不带断口槽的踏板臂进行分析,找出踏板臂上最大应力位置。在产品模型上相应位置设置不同参数的断口槽,进行比较分析,从而确定合适的断口槽形状和尺寸参数。根据设定的参数,试制出样件,并进行了实验验证。分析和实验表明,在加速踏板臂最大应力位置开设合适形状和尺寸的断口槽,能满足使用要求和特定的安全规范。
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.
