摘要
EV矿用自卸车电池包支架由于需要搭载大型电池包而对强度有较高要求,但是在对其整体结构及各项性能进行加强的同时又需要限制其质量指标的增加量,因此,对于结构设计而言,需要在严格的质量指标限制下,在达到强度要求的同时,提升其性能。为此,结合有限元分析与随机振动试验原理,提出一种新的试验方法对其强度进行试验验证,基于CAE仿真结果及相关优化方法,可在其质量增加量不超过1%的前提下优化支架结构,从而使电池包支架的结构强度得到有效提升。
EV mine dump truck battery pack bracket has higher strength requirements because it needs carry large battery pack.However,the overall structure and performance should be strengthened while the increase of its mass index should be limited.Therefore,it is necessary to meet the strength requirements and improve its performance under the strict limit of mass index for structural design.Therefore,a new test method based on the finite element analysis and random vibration test principle to verify its strength and reliability was proposed.Based on the CAE simulation results and optimization methods,the bracket structure can be optimized under the premise that its mass increase does not exceed 1%.Thus,the structure strength of the battery pack bracket is effectively improved.
