液压支架的设计及有限元分析 对于综合采工作面，高产高效的关键就是液压支架正常稳定运行液压对采煤工作面的有效支护通过应用液压，配合的机械结构能够完成的动作和的效果。液压支架是煤矿综采工作面装备使用的装备也是的技术装备基于在液压支架的开发设计过程中，支架的安全可靠性以及技术上的重点都是基于已有的液压支架相关知识的研究内容。 以四柱支撑掩护式液压系统的设计以及有限元分析，对其进行科学的设计。 通过分析液压支架的工作环境外载荷特性进而的液压系统基本回路、工况等等进行分析通过计算数据，出液压的系统基本原理图 针对本文的的液压支架三维软件ProE进行相关建模导入ANSYS，进行相关的模型简化网格划分等等相关操作分析其元部件的应力应变变化情况，得到该三维建模后的液压支架的下不同零部件的应力、载荷等的应力云图。通过应力云图相关分析，最终液压支架在设计以及受力分析时注意的意见。 是有限元和建立液压系统为基础的现代设计方法的应用对液压支架的完全设计具有一定的意义，对于解决相关的工程知识问题应用的意义。 三维建模 有限元分析 ANSYS  and finite element analysis of hydraulic support Abstract As the fully-mechanized face in the coal mine, the work of coal mining need to be high yielding and highly effective. And the key to the mature work is he hydraulic support could operate normal and stable. Effective hydraulic support in coal mining face support is through the application of the hydraulic system, and cooperate with related mechanical structure of the hydraulic support can complete the pre-set each movement and the need to achieve the effect. Hydraulic support in coal mine fully mechanized working face of equipment most frequently used equipment, is also very important, of course, production technology and equipment. For these reasons, in the process of the development of the hydraulic support design, the safety and reliability of the stent and focus on the technology, is based on the existing knowledge content in the research of hydraulic support. In this paper, taking a mine production under the condition of four pillars support the shield hydraulic support, the design of the hydraulic system and the finite element analysis on the design of science. First of all, through the analysis of the working conditions of hydraulic support and external load characteristics, basic circuits of the hydraulic system of hydraulic support, working condition and so on carries on the analysis to the relevant data is obtained by calculation, and then draw out the basic principle of the hydraulic system diagram. Then using 3D software Pro/E to com
