【摘要】：针对重汽王牌公司生产的重型卡车双层车架总成出现断裂情况,采用有限元结构应力应变分析技术对重型卡车车架进行优化设计改进,获取原双层车架断裂的原因,提出了单层车架改进优化与轻量化设计方案,通过其结构应力应变对比分析、试车实验验证,表明改进优化后的单层车架强度及刚度明显提高并能满足设计要求,减轻了重量。此技术已成功应用于现行产品批量生产中,市场反应良好,使企业获得了良好的社会经济效益。
[Abstract]:In view of the fracture of the double deck frame assembly of heavy duty truck produced by heavy truck trump Company, the finite element structural stress and strain analysis technology is adopted to optimize the design of heavy truck frame, and the reasons for the fracture of the original double deck truck frame are obtained. An improved optimization and lightweight design scheme for single-layer frame is put forward. Through comparative analysis of structural stress and strain and test test, it is shown that the strength and stiffness of the improved single-layer frame are obviously improved and can meet the design requirements. The technology has been successfully applied in the batch production of current products, and the market reaction is good, which makes the enterprise obtain good social and economic benefits.
