摘要
轮毂单元是汽车系统的重要部件,其力学性能成为直接影响汽车安全性能的关键因素。通过对轮毂的各项力学性能合理精确的有限元分析,可以优化轮毂设计、保证强度要求、减少试验次数、缩短开发时间。以第一代轮毂轴承单元为研究对象,以ANSYS为工具,建立与轮毂实际弯曲疲劳试验相等效的有限元分析模型,并进行结构强度分析,获得轮毂单元的静应力分布,为轮毂产品的设计开发提供设计依据。
Wheel hub unite is an important component in the vehicle system, and its mechanic performance of wheel hub unite directly determines the security of vehicle. Using accurate and rational finite element analysis of the wheel hub mechanic properties, the designers can optimize the design of wheel, secure the strength, cut down experiment number and reduce the design time. Based on the a first generation wheel hub unite, a simulation of stress field was made under rotary fatigue conditions by finite element software ANSYS with parameters finite element method, stress field distribution of wheel hub were acquired, which can provide the important design guide for wheel design engineers.
