摘要
从动力学的角度出发,以某挖掘机机液工作系统为对象,应用机器人理论建立该工作系统机构的动力学方程.在AMESim软件中分别建立机液工作系统的机构和LUDV(Lastdruck-Unabhaengigen DurchflussVerteilung)液压系统仿真模型,仿真计算该工作系统的机液耦合动态特性.结果表明:该系统具有较好的操纵性和流量抗饱和特性,此方法可以为挖掘机机液工作系统的优化设计提供参考.
Pertaining to the dynamical analysis on the hydro-mechanical working system of a specific excavator,a dynamical equation is first obtained based on robotic theory.Then,the mechanism of hydromechanical working system,together with the simulation model of LUDV hydraulic system,is established using AMESimTM.Next,the dynamic properties of hydro-mechanical coupling are calculated.Finally,this system,which possesses good controllability and anti-saturation flow property,sets a reference to optimization design for excavator hydro-mechanical working system.
