伸臂式焊接变位机带传动的优化设计及仿真分析

焊接技术是装备制造业中的核心技术之一。带传动是伸臂式焊接变位机减速机构中传递运动和动力的重要装置。利用MATLAB对带传动装置进行多目标优化设计,在满足承载能力的条件下,实现了带的根数尽量少、带轮直径和中心距尽量小,使得传动结构更加紧凑。利用RecurDyn软件对优化后的传动系统进行运动仿真分析,建立传动带虚拟样机模型,得到相关运动学曲线,为带传动的设计和计算提供了理论依据。

Optimal Design and Simulation Analysis for Belt Transmission of Cantilever Welding Positioner

Welding technology is one of the core technology of equipment manufacturing.Belt transmission is an important device of reducing mechanism of cantilever welding positioner to transmit motion and power.Using MATLAB,multi-objective optimization for belt transmission device was realized. The number of bands was reduced in meeting the conditions of carrying capacity.The diameters of the pulley and center distance were reduced.So the transmission structure was more compact.Using RecurDyn software,simulation analysis for belt transmission was carried out.The virtual prototype model of the belts was established.The relevant kinematic curve was obtained.It provides theoretical basis for design and calculation of belt transmission.
