| 摘 要： | 农用液压挖掘机的工作装置有其特殊性,而铲斗机构是其重要的组成部分.由于农用挖掘机工作时主要以铲斗挖掘,所以铲斗机构的设计合理与否尤为重要.为此,针对铲斗机构进行理论分析,认为铲斗机构属于平面多体系统,应用多体系统动力学中的凯恩-休斯顿法分析了系统的运动学问题,利用拉格朗日法分析了系统的动力学问题,并分别给出了相应的运动学方程.最后,用ADAMS软件进行了联合仿真,得到了动力参数曲线,为优化设计和自动控制提供了理论依据.

| Abstract: | The working device of agricultural hydraulic excavators has its specificity,and shovel unit belongs to an important component of it.As agricultural hydraulic excavators mainly use shovel to dig,it is particularly important that the shovel unit's design is reasonable or not.This article aims to the theoretical analysis of the shovel unit.The shovel unit is a plane multibody system.It's kinematics has analyzed in application to Kane-Houston law,dynamics in application to lagrange law separately.Then correspon... |
