以热电池电堆自动缠绕机为研究对象, 根据电堆缠绕的实际工艺要求, 对电堆缠绕机进行了设计, 并对缠绕机进行了静力学和动力学分析。首先对机器进行三维建模, 建立缠绕机的有限元模型, 在Workbench中对上主轴和下地板进行强度分析, 得到主轴在夹紧电堆且满足一定压力情况下的最大应力和应变值。对滑台进行动力学分析, 得出滑台的速度及加速度关系曲线。分析结构的薄弱点, 进一步对结构进行优化和改进。改进后的结构在受同等力的情况下, 应力和应变值明显减小, 能够满足工作要求。通过以上设计分析, 为热电池电堆缠绕机的设计提供了理论依据。

Taking the automatic winding machine for thermal battery stack as the research object, according to the actual technological requirements of winding, the winding machine for thermal battery stack is designed and the static and dynamic analysis of the winding machine is carried out. The three-dimensional model of the machine is built, and the finite element model of the winding machine is established. The strength of the upper spindle and the lower floor is analyzed in workbench, and the maximum stress and strain of the spindle when clamping the stack and satisfying certain pressure are obtained. The dynamic analysis of the sliding platform is carried out, and the relationship curves of velocity and acceleration of the sliding platform are obtained. The weaknesses of the structure are analyzed to further optimize and improve. Under the same stress, the stress and strain values of the improved structure are obviously reduced, which can meet the working requirements. The above design analysis provides a theoretical basis for the design of thermal battery assembly machine.
