摘要

四连杆是掩护式支架和支撑掩护式支架的最重要部件之一，其作用概括起来主要有两。一是当支架由高到低变化时，借助四连杆机构使支架顶梁前端点的运动轨迹近似双纽线。从而使支架顶梁前端点与煤壁间距离的变化大大减小，提高了管理顶板的性能；二是使支架承受较大的水平力。这篇文章就是讨论液压支架四连杆机构的。

在文章里，我们研究了液压支架四连杆机构所面临的问题，及可以从几个方面考虑解决的方法。文章研究的是液压支架四连杆机构，液压支架四连杆机构是矿上机械——液压支架的关键部件。文章对四连杆机构和液压支架整体进行了研究。

文章还对四连杆机构的动态特性进行分析，在此过程中运用了SolidWorks中的COSMOSMotion进行建模和运动仿真。

FOUR-BAR LINKAGE DESIGN OF THE

MODELING AND OPTIMIZATION

ABSTRACT

Four-link is the shield support bracket and support shield one of the most important components, its role can be summarized as two. First, when the support changes from high to low, with four-bar linkage so that the front support beam trajectory point approximation lemniscates. So that the front support beam points away from the wall of the changes with the coal greatly reduced, improving the management performance of the roof; Second, the level of support to withstand greater force. This article is to discuss four hydraulic linkage mechanisms.

In the article, we study the four-bar linkage hydraulic problems, and can be considered from several aspects of the solution. This paper studies the four hydraulic linkage, hydraulic four-bar linkage is mine machinery - the key hydraulic components. Article on the four-bar linkage and hydraulic support the overall studied.

Paper also the dynamic characteristics of four-bar linkage analysis, in the process of the Application of the SolidWorks COSMOSMotion in modeling and motion simulation.
