摘要
针对伺服机械压力机三角肘杆传动机构,根据机构运动学与动力学理论,以滑块下死点位置为初始状态建立数学模型进行优化设计;以传动机构水平尺寸x为单位长度,以其他杆长与x比例的相对长度和曲柄的初始转角为优化变量,不但可以减少优化变量,还可以使优化过程变得简单、精确,且滑块行程可控。采用MATLAB软件优化工具箱实现了机构运动与动力的优化,采用ADAMS软件建模并进行仿真检验,证明优化结果可靠实用。
For the triangle toggle transmission of servo mechanical press,the mathematical calculation mode of kinematics and dynamics was established with the original condition of the slider at the bottom dead center. Putting the percentage of rod length to horizontal size x and the initial angle of crank as the optimization variables, the kinematic and dynamic optimization have been done by using MATLAB optimization toolbox. The ADAMS modeling simulation tests prove the optimization results to be practical and reliable.
