【Abstract】 Toprovide the appropriate driving force for a new type of wide-width loom servo dobby shedding device, a mechanical and simulation analysis is conducted to select the suitable servo motor. The motor motion parameters are optimized through analysis to meet the control requirements for shedding. A three-dimensional solid model and a mechanical mathematical model are established. Using MATLAB and simulation results, parameters such as torque and inertia are determined to select the appropriate servo motor. The motion control parameters are then optimized based on the harness motion pattern. Finally, the setup is verified on an experimental platform. The results show that the selected servo motor meets the driving and control needs of the wide-width device, achieving the required clear shed. The optimized motion reduces warp yarn breakage, minimizes loom vibration, improves stability, and enhances machine lifespan and weaving efficiency.更多还原
