摘　　要：随着新能源需求的持续增长和可再生能源技术的迅猛发展,储能电池的应用日益广泛。储能电池的安全性能在安装和运输过程中的表现尤为关键,因此,设计高性能的结构部件成为提升系统安全性和可靠性的研究热点。为了提高储能电池在安装和运输过程中的安全性能,本文针对一种可以装配在储能电池的外部端板通过Ansys Workbench平台开展了一系列的静力学分析。具体而言本文通过改变端板的材料、厚度、槽钢数量和布局、载荷及受力面积,对端板结构变形特性的影响进行了系统研究。研究结果表明,添加槽钢显著增强了结构的整体强度和刚度,能够有效减少弯曲和变形,特别是在承载较大电池模块重量时。两对或三对槽钢在保持合理重量的同时提供了较好的抗变形能力,而槽钢的布局间距对整体强度也起到关键影响。此外,端板厚度的增加对减小变形起到了明显的作用,变形量随着厚度增加呈现非线性下降趋势;受力区域越大,配备两对或三对槽钢的端板在变形程度上的差异更小,表明优化端板结构设计是增强整体强度的有效手段。为储能电池盖板的设计提供了新的思路和方法,对于提高储能系统的整体性能具有重要意义。With the continuous growth in demand for new energy and the rapid development of renewable energy technologies,the application of energy storage batteries has become increasingly widespread.The safety performance of energy storage batteries during installation and transportation is particularly critical,making the design of high-performance structural components a research focus for improving system safety and reliability.To enhance the safety performance of energy storage batteries during installation and transportation,this study conducted a series of static analyses on an external end plate that can be installed on energy storage batteries using the Ansys Workbench platform.Specifically,the effects of various parameters,including the material,thickness,number and layout of channel steels,applied load,and load-bearing area,on the deformation characteristics of the end plate structure were systematically investigated.The results show that adding channel steels significantly improves the overall strength and stiffness of the structure,effectively reducing bending and deformation,especially under the weight of larger battery modules.Two or three pairs of channel steels strike a balance between maintaining reasonable weight and providing good anti-deformation capacity,while the spacing of the channel steels plays a crucial role in determining the overall structural strength.Furthermore,increasing the thickness of the end plate effectively reduces deformation,with the deformation showing a nonlinear decrease as thickness increases.As the load-bearing area increases,the difference in deformation between end plates equipped with two and three pairs of channel steels becomes smaller,highlighting that optimizing the structural design of end plates is an effective approach to enhancing overall strength.This study provides new insights and methods for the design of energy storage battery end plates,which are of great significance for improving the overall performance of energy storage systems.
