Design and Development of Lightweight Wheels of Heavy Off-road Vehicle

本文根据铝合金车轮在重型越野汽车上的工程应用,及其加工工艺,设计了铝合金车轮的结构型式及特性参数。并以ANSYS软件为工具,对越野汽车车轮进行受力分析,详细准确地确定了车轮的受力情况和应力分布部位,依托分析结果对车轮进行优化,达到降低车轮关键部位应力的目的。并通过实际装车试验验证,结果显示该重型越野汽车轻量化车轮产品设计的合理性、可靠性,解决了车辆轻量化的问题,提高了整车的质量利用系数。

According to the engineering application of aluminum alloy wheels in the heavy off-road vehicle and their processing technology,the structure type and characteristic parameter of aluminum alloy wheels are designed.By means of ANSYS software,stress analysis is carried out on the wheels of the heavy off-road vehicle.Both stress condition and stress distributions of the wheels are identified precisely.The wheels are optimized relying on the results of the analysis,to reduce the stress of key parts of the wheels.And it is verified through the actual loading test.The results show that the product design of the wheels of the heavy off-road vehicle is reasonable and reliable.The problem of lightweight vehicle is solved,and the quality utilization factor of the vehicle is improved.
