摘要
介绍了铲运机负荷传感型全液压转向系统的工作原理,运用ADAMS软件建立铲运机的多体动力学模型,AMEsim软件建立铲运机液压转向系统仿真模型,并以AMEsim为主体仿真软件,对转向过程中不同转向条件下转向油缸压力进行联合仿真,并分析仿真结果。仿真结果表明:加快转速时油缸压力脉动增加,增加负载时压力平均值增加。针对转向过程中转向油缸液压油的脉动问题,利用遗传算法对油缸铰接点位置进行优化设计。优化结果表明:优化后的系统油缸压力脉动大大减小,优化有效。
The working principle of the load-sensing full hydraulic steering system of scraper is introduced. The multi-body dynamic model is established based on ADAMS and the hydraulic simulation model is established based on AMEsim. Taking AMEsim as the master, the pressure of steering cylinders during the steering process are co-simulated and analyzed under different conditions. Simulation results show that the pressure fluctuation of oil cylinder increases when rev up and the average pressure increase when the load up. In view of the pressure fluctuation of cylinders during the steering process , the position of cylinders hinge joint is optimized based on GA.It is found that the pressure fluctuation are greatly reduced.
