旋挖钻机作业装置的动力学分析

Dynamic Analysis of Working Device of Rotary Drilling Rig

由于旋挖钻机质量大、输出扭矩大,所以对旋挖钻机的主要部件进行力学分析十分重要。针对旋挖钻斗钻进过程、回转机构运动过程和变幅机构变幅过程进行了分析,能为旋挖钻机的设计提供一定的理论参考。

As the rotary drilling rig is very heavy and it works at a very high pulling torque, it is very important to have a dynamic analysis on the main components of working device of rotary drilling rig. The drilling process the movement of swing mechanism and the luffing process of jib luffing mechanism were emphasized. This analysis can provide some theoretical reference for the design of rotary drilling rig.
