基于Unity3D的卷绕机半物理仿真系统研究

Hardware-in-the-Loop Simulation System Based on Unity3D for Winding Machine

机电一体化产品在研发过程中普遍面临现场调试工作量大、周期长和成本高等问题,而且目前主流的仿真软件功能较为单一。因此,研究设计了一套兼具实时性和三维展示效果、能够连接机械电子软件的半物理仿真系统。其以卷绕机为仿真对象,利用Unity3D搭建虚拟仿真平台,通过电路板实现虚拟仿真平台与控制系统间数据的实时交互。通过输出卷绕过程中关键结构的运动时序和空间轨迹图,验证了卷绕机机电系统的工艺仿真可行性。研究结果表明,该系统可替代部分现场调试工作,提高研发效率。

Research and development of mechatronic products generally face the problems of large workload,long cycle and high cost of on-site debugging,and the current mainstream simulation software has a single function.Thus,a set of hardware-in-the-loop simulation(HILS)system with both real time and a three-dimensional(3D)display effect is designed,and can be connected to the mechatronic software.The winding machine is taken as the simulation object,a virtual simulation platform using Unity3D is built,and the real-time interaction of data between the virtual simulation platform and the control system is realized through the circuit board.The feasibility of the process simulation of the electromechanical system in the winding machine is verified by outputting the motion timing and spatial trajectory diagrams of the key structures in the winding process.The results show that the system can replace part of the on-site debugging work and improve the efficiency of research and development.
