| 摘 要： | 为了对某型电动汽车锂离子动力电池仓进行轻量化设计,采用SFE Concept软件平台,建立电池仓的隐式全参数化模型。结合iSight平台,建立电池仓的优化流程。以电池吊装构件装配位置及关键零件壁厚为设计变量,以电池仓整体质量为优化设计的目标函数,以结构刚度、强度、疲劳耐久、NVH(噪声、振动、声振粗糙度)性能为约束条件,并利用了pointer算法。结果表明:参数优化后的动力电池仓的质量,减少了2.6%。因而,此方法对电池仓结构的正向设计开发具有参考价值。

| Abstract: | An implicit full parameterized model was established for lithium-ion power battery compartments of electric vehicles(EV)by using a software platform of SFE Concept to realize EV lightweight design.An optimization process of battery compartments was established by combining an iSight platform.The assembly position of battery hoisting components and wall thickness of key components were taken as design variables,and the overall quality of battery compartment was taken as the optimal-design objective function,while the structural stiffness,strength,the fatigue endurance and the NVH(noise,vibration,harshness)performance were taken as constraint conditions,and using a pointer algorithm.The results showed that the battery mass was reduced by 2.6%after parameter optimization.Therefore,this method has some references for the forwarddesign and development of battery compartment structure. |
