Design and Analysis of Experimental Platform for a Hybrid-Driven Two-DOF Nine-Bar Press

  • 摘要: 混合驱动机械式压力机主要由伺服电机和常速电机通过二自由度机构进行驱动,其具有功率大、刚度大、可调控等特点。基于二自由度九杆机构,设计了一种150 kN的混合驱动压力机实验平台。采用Solidworks完成混合驱动压力机实验平台的结构设计;利用ADAMS对实验平台进行运动学和动力学仿真分析,据此对实验平台的常速电机和伺服电机进行选型设计;运用Ansys对机架、偏心轮、曲轴和摆杆轴等主要零部件进行应力和应变分析。该研究为压力机实验平台工作的稳定性和安全性提供了保证,也为设计人员及本科学生提供一种应用工程软件完成机械装备设计的方法。

     

    Abstract: The hybrid driven press is mainly driven by a servo motor and constant speed motor through a 2 DOFs mechanism. The constant speed motor provides the main power for the system and the servo motor is mainly used to regulate the movement of the system. The hybrid driven press has the advantages of large power, large rigidity and adjustable control. Based on multi-link mechanism, a 150 kN hybrid drive press experimental platform is designed. The structure of the press experimental platform is designed by Solidworks, the kinematics and dynamics simulation of the mechanism of experimental platform is carried out through ADAMS, and the constant speed motor and servo motor of the press experimental platform are selected. This article uses Ansys to perform stress and strain analysis on the main components such as fuselage, eccentric wheel, crankshaft and pendulum shaft. The research can not only ensure the safety and stability of the press experimental platform during its operation, but also provide a method for designers/undergraduates to complete mechanical equipment design by applying engineering software.
