The Analysis of Mechanical-hydraulic Co-simulation of Hydraulic Outrigger——Based on ADAMS and AMESim

以机械平衡用的果园多功能移动作业平台液压支腿为研究对象,分别建立了实体模型与液压回路模型,通过机构简化与分析构建了支腿运动方程;分析了双作用单活塞杆在液压缸内速度以及缸内液体压力的变化规律,利用ADAMS和AMESim软件进行了参数化设计及联合仿真,并对仿真结果进行了分析。其结果证明了液压支腿机械液压联合仿真控制闭环模型的可行性,为液压支腿设计与优化提供了捷径,使结构设计与仿真模型更符合工程实际,有助于提高系统性能。

Mechanical equilibrium hydraulic legs were used as the object of study,its solid model and hydraulic circuit model were builded respectively,simplified institutions and the analytic method were used to get its equation of motion;the variation of single-rod double acting hydraulic cylinders' speeds and hydraulic pressures on both sides were analyzed,the software ADAMS and AMESim were used to go on parametric designs and softwares' co-simulation,then simulation results were analyzed,and the feasibility of the control of the hydraulic closed-loop model between Mechanical system and hydraulic system co-simulation was proved.A shortcut was provided for the design and optimization of hydraulic legs,it allowed us to design more in line with the simulation model to meet the engineering practice,and helped improve system performance.
