摘要:

为解决因横动导丝形变量过大而造成的高速卷绕机空转问题，实现对机械设备元件的有效控制，设计基于STM32F103的高速卷绕机横动导丝控制系统。在CPU主控电路体系中，设置STM32F103控制器元件，并以此为基础，控制锭轴夹头、机械卷绕头两类机械零部件，完成控制系统的主要应用模块设计。按照变卷装转化原则，判断设备元件之间的联接关系，再根据横动导丝同步涡动频率求解结果，推导弹性微分方程，实现对高速卷绕机的动力学建模处理。分别求解边界条件与有限元模态系数，实现对模态控制量的精准计算，结合相关应用部件结果，完成基于STM32F103的高速卷绕机横动导丝控制系统设计。实验结果表明，上述系统作用下，空卷状态下导丝形变量不超过0.77mm、满卷状态下导丝形变量不超过8.35 mm，始终达不到10mm的变形极值，可以解决高速卷绕机的空转问题，符合有效控制机械设备元件的实际应用需求。

Abstract:

In order to solve the idling problem of the high-speed winding machine caused by the excessive shape variation of the traverse guide wire and realize the effective control of the mechanical equipment components, the traverse guide wire control system of the high-speed winding machine based on STM32F103 is designed. In the CPU main control circuit system, STM32F103 controller elements are set, and on this basis, the spindle collet and mechanical winding head are controlled to complete the main application module design of the control system. According to the principle of variable package transformation, judge the connection relationship between the equipment components, and then derive the elastic differential equation according to the solution result of the synchronous whirl frequency of the traverse guide wire to realize the dynamic modeling of the high-speed winding machine. The boundary conditions and finite element modal coefficients are solved respectively to achieve accurate calculation of modal control quantity. Combined with the results of relevant application components, the design of traverse guide wire control system of high-speed winding machine based on STM32F103 is completed. The experimental results show that under the action of the above system, the shape variation of the guide wire in the empty winding state is not more than 0.77 mm, and the shape variation of the guide wire in the full winding state is not more than 8.35 mm, and the deformation extreme value of 10 mm can not be reached all the time, which can solve the idling problem of the high-speed winding machine and meet the practical application requirements of effectively controlling the mechanical equipment components.
