摘要
为了达到汽车零部件轻量化的目标,该文以某SUV电动车的发动机盖为研究对象,提出选用碳纤维复合材料替代传统钢材的方案,并通过CAE软件仿真分析其扭转刚度、侧边中部刚度、中后部刚度及1阶约束模态等各项性能指标,分析结果表明:碳纤维复合材料的各项性能指标均能满足设计目标值且优于钢材性能,实现了减重47%的目标。同时,针对设计过剩问题,提出了尺寸优化的参考方向。
In order to reach the target of automotive parts lightweight, taking the engine cover of an SUV electric vehicle as the research object, the use of carbon fiber composite materials to replace the traditional steel material program is proposed in this paper, analyzing the torsional stiffness, the side middle stiffness, the middle stiffness and the first order restraint mode by CAE simulation software. The results show that the performance index of carbon fiber composite materials can meet the target value, and is better than steel materials, achieving the goal of 47% weight reduction. At the same time, the plan of size optimization for design surplus is put forward.
