摘　　要：为提高铲刀带载回转能力,提出一种双油缸加回转阀摆动回转的新型平地机铲刀回转结构,并阐述其工作原理。通过分析回转过程中各油缸作用关系,推导出新结构回转过程运动学方程,并基于Matlab仿真分析获取不同流量下的运动学特性。本文结果可为平地机摆动回转结构设计提供参考和依据。In order to improve the rotary ability of the blade to carry the load,a new kind of rotary mechanism for the blade of motor grader with double cylinders and swing rotary valve was proposed,and the working principle of the rotary mechanism was expounded.The kinematic equation of new rotary mechanism was deduced by analyzing the relationship of the rotary cylinder in the rotary process.Based on the Matlab simulation,the kinematic characteristic of vary flow was obtained.This analysis can provide reference for the design of rotary mechanism.
