摘　　要：为在满足企业收卷机动态称重精度情况下,找出适合其生产现状的最佳卷取方式,提出了一种基于张力信号空间分解的动态称重方案。同时结合理论力学和动力学等理论,对比分析了恒张力(恒线速度)、恒转速、锥张力三种控制条件下的信号特征及误差模型,并对最终所选定的恒转速收卷方案进行了实验验证。实验结果表明,所测实时重量相对误差小于0.5%,收卷操作稳定、效率高,满足企业要求。In order to find out the most suitable dynamic rolling mode for the winding equipment with a proper precision, a dynamic weighing system is presented based on tension measurement. Furthermore, combining with theoretical mechanics and dynamics, weight signal feature and error model of three different control schemes-constant tension （constant linear velocity）, constant rotating speed and taper tension are analyzed comparatively. Experiment results of constant rotating speed control scheme show that the system is stable and efficient; moreover, weighing error can be reduced within 0.5%.
