基于遗传算法的双曲柄伺服压力机杆系的优化设计

摘要

Double crank servo press has the characteristics of low speed quick return and increasing force.Through the establishment of double crank rod system model,with the help of programming tools and genetic algorithms,the double crank rod system parameters have been designed for the single objective optimization.The slider displacement,velocity and acceleration have been analyzed,as well as the required torque curve of the big gear.The power of the servo motor has been effectively reduced.It provides certain theoretical calculation basis for the design of large tonnage servo press.%双曲柄伺服压力机具有低速急回和增力的特性.通过双曲柄杆系模型的建立,借助语言编程工具,利用遗传算法,进行单目标优化设计.据此设计了双曲柄杆系参数,分析了滑块位移、速度、加速度以及大齿轮所需转矩曲线.有效降低了伺服电机功率,为大吨位伺服压力机的设计提供一定的理论计算基础.
