基于 ADAMS 的四索长撑杆抓斗运动学仿真分析

摘要

In this paper ,a 25 t grab 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 .%以25 t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。
