摘　　要：包覆面料裁片切割机是用于制作软体家具的主要设备之一,其横梁进给系统存在复杂的机电耦合作用。为在设计阶段研究其横梁进给系统切割定位工况下的动态特性,优化横梁进给伺服驱动控制系统参数,建立了横梁进给系统的机电-刚柔混合模型。拟定横梁进给系统的响应效率、定位精度和刀尖运动稳定性作为动态特性评价指标,探究了横梁进给伺服驱动控制系统参数对横梁进给系统动态特性的影响。结果表明:建立的横梁进给系统机电-刚柔混合模型,为横梁进给系统动态特性分析奠定了基础。增大位置环比例系数可提高横梁进给系统的响应效率和定位精度,增大速度环比例系数可有效提高横梁进给系统的刀尖运动稳定性。研究结果可为提高软体家具生产效率和制造质量提供技术保障。Covered fabric cutting machine is one of the main equipment used to make soft furniture,and its beam feed system has complex electromechanical coupling effect.In order to study the dynamic characteristics of the beam feed system under cutting positioning conditions during the design stage,and to optimize the parameters of the servo drive control system of the beam feed system,a virtual prototype model of the beam feed system was established in this study.Evaluation indexes for the dynamic characteristics of the beam feed system,including response efficiency,positioning accuracy,and tool tip motion stability,were proposed.The influence of servo drive control system parameters on the dynamic characteristics of the beam feed system was analyzed.The results showed that the established electromechanical-rigid-flexible coupling model provided a foundation for the dynamic characteristics analysis of the beam feed system.Increasing the proportional coefficient of the position loop enhanced the response efficiency and positioning accuracy of the beam feed system,while increasing the proportional coefficient of the speed loop improved the tool tip motion stability of the beam feed system.This study could provide technical support for improving the production efficiency and manufacturing quality of soft furniture.
