基于运动学分析的铝箔复卷机的结构优化与动态仿真

Structural Optimization and Dynamic Simulation of Aluminum Foil Rewinder Based on Kinematic Analysis

针对铝箔复卷机高速工作状态时关键核心组件失效及其设备稳定性不足等问题,采用主模型技术完成复卷机的三维建模,通过定义刚体和施加约束,对模型进行运动学分析,通过对核心组件进行结构优化与动态仿真,提高复卷机的性能参数。顶料轴组件是复卷机的关键核心组件,所以本文对复卷机的顶料轴组件进行了动态仿真分析,通过顶料轴的位置、速度以及加速度曲线的优化完成凸轮机构的设计,最后通过对顶料轴的受力曲线分析完成顶料轴结构的优化。将优化后的核心组件应用到复卷机中,实现了复卷机的高速性能及其稳定性要求,优化后的复卷机最终投入到生产实践中。

Aiming at the failure of the key component at the high-speed state and the insufficient stability of the equipment,we apply the master model technology to complete three-dimensional modeling of the rewinder. Then the comprehensive analysis of kinematics can be conducted after the rigid is defined and the constraints are imposed. The structural optimization and dynamic simulation of the core components are conducted to improve the performance parameters of the rewinder. The dynamic simulation analysis of the rewinder' s ejector shaft which is the core component is made. The curve of position,velocity and the acceleration of the ejector shaft are optimized with the design of the cam mechanism. Finally,the optimization of structure of the ejector shaft is completed by analyzing the force curve. The optimized core components are applied to rewinding machine and achieve high-speed performance and stability requirements. The optimized rewinder is ultimately put into practice and achieve the desired results.
