摘要
该文设计了一种能提供低速大扭矩的油缸驱动机构,分析了其工作原理,建立了多个机构并联驱动的动力学方程,讨论了不同数目机构驱动时驱动转速及液压系统压力波动情况,通过遗传算法优化了机构的结构参数,在一定程度上减小了系统波动。根据计算分析,采取奇数多个此种机构并联驱动可以为系统提供较为稳定的驱动扭矩。
In this paper, a kind of oil-cylinder driving mechanism is introduced to provide low-speed and high torque. Then its working principle is analyzed, the dynamic equations of multi-mechanism parallelly driving is established, the fluctuation issues of rotary speed and hydraulic pressure with a different number of mechanisms is discussed, and genetic algorithm is applied to optimize the mechanism＇s structure parameters in order to reduce fluctuation. According to analysis of calculation, odd and multiple mechanisms can provide relatively stable drive torque.
