摘要
纤维缠绕复合材料具备优异的比强度及良好的可设计性,被广泛应用于航天航空等高技术领域。目前,国内纤维缠绕成型技术的研究多集中在缠绕理论及CAD/CAM软件方面,关于纤维缠绕在线虚拟仿真技术的开发尚处于起步阶段。本文通过OpenGL软件建立物理机床的虚拟映射,提出一种新的缠绕轨迹反向求解计算方法,对纤维缠绕过程中的纤维轨迹进行实时显示;通过Modbus TCP协议建立虚拟机床与物理机床之间的联系,实现了对纤维缠绕过程关键参数的实时监测;通过华中9型数控系统提供的NC-API接口实现了虚拟机床与物理机床之间的数据交换及部分操作指令的双向控制。缠绕试验表明,基于数字孪生技术开发的纤维缠绕虚拟仿真系统能够完成纤维缠绕过程的实时运动仿真、缠绕过程关键参数的监测及对缠绕过程的直接控制,并验证了纤维缠绕过程远程监测、远程控制等功能的可行性。
Fiber winding composites are widely used in high-tech fields such as aerospace due to their excellent specific strength and good designability.However,current domestic research on fiber winding molding technology is mostly focused on winding theory and CAD/CAM software,and the development of online virtual simulation technology for fiber winding is still in its early stages.This study proposed a new calculation method to display the fiber trajectory in the fiber winding process in real-time by establishing a virtual mapping of the physical machine tool through OpenGL.The link between the virtual machine tool and the physical machine tool was established via the Modbus TCP protocol to enable real-time monitoring of key parameters in the fiber winding process.In addition,bi-directional data exchange between the virtual machine tool and the physical machine tool,as well as control of some operation commands,was achieved through the NC-API interface provided by the Huazhong 9 CNC system.The winding experiments show that the fiber winding virtual simulation system developed based on digital twin technology can complete the real-time motion simulation of the fiber winding process,the monitoring of key parameters of the winding process and the direct control of the winding process.This study has completed the functional requirements of remote monitoring and remote control of the fiber winding process.
