摘要
为了获取某轻卡蓄电池支架的整体性能,首先建立有限元网格模型,约束车架两端,得到其前三阶模态频率,与激励频率范围不重叠,符合模态性能要求。基于采集的振动加速度对蓄电池支架进行强度性能分析,获取其应力水平,均低于材料屈服值,满足强度性能要求。再通过集成优化得到蓄电池支架的最佳结构,并且成功减重15.9%,实现了轻量化设计。
In order to obtain the overall performance of a light truck battery bracket,a finite element grid model is established to constrain both ends of the frame,and the first three modal frequencies are obtained,which do not overlap with the excitation frequency range and meet the modal performance requirements.Based on the collected vibration acceleration,the strength performance of the battery bracket is analyzed,and the stress level is lower than the material yield value,which meets the strength performance requirements.Then the best structure of the battery bracket is obtained through integrated optimization,and the weight is reduced by 15.9%successfully,and the lightweight design is realized.
