基于ADAMS的四索长撑杆抓斗运动学仿真分析

ADAMS Based Kinematics Simulation of Grab Bucket with Four-rope and Long Stay Bar

以25t四索长撑杆抓斗为例,从单纯的机构学的观点出发,将四索长撑杆抓斗视作一个曲柄连杆机构,利用动力学分析软件ADAMS分析了抓斗机构的运动。首先建立了抓斗机构的运动学模型,并定义运动副、添加驱动以及施加驱动,然后通过后处理模块对抓斗进行运动分析,所得结论为今后抓斗的优化提供了参考依据。

In this paper,a 25 tgrab bucket with four-rope and long stay bar is taken as example.Based on the simple mechanism theory,the grab bucket is simplified as a crank connecting rod mechanism.The motion mechanism of grab bucket is analyzed by using ADAMS dynamic analysis software.Firstly,the kinematic model of the grab bucket is established;Then,the motion pair is defined,and drive is added;Finally,the post-processing module is used to conduct the grab bucket motion analysis.The conclusion provides a reference for the optimization of grab bucket.
