液压支架的设计及有限元分析
对于综合采煤工作面来说，要满足使其高产高效的关键就是液压支架能够正常稳定地运行。液压支架对采煤工作面的有效支护是通过应用液压系统，并且配合相关的机械结构使液压支架能够完成预先设定的各个动作和需要达到的效果。液压支架是在煤矿综采工作面装备当中使用频率最高的装备，当然也是极其重要的生产技术装备。基于这些原因，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，都是本文基于已有的液压支架的相关知识的研究内容。
本文通过以某矿井生产条件下的四柱支撑掩护式液压支架进行液压系统的设计以及有限元分析，对其进行科学的设计。
首先通过分析液压支架的工作环境和外载荷特性，进而对液压支架的液压系统基本的回路、工况等等进行分析从而通过计算得到相关数据，进而绘制出相关液压回路的系统基本原理图。
针对本文的需要研究的液压支架，首先利用三维实体建模软件Pro/E进行相关建模并导入进ANSYS，进行相关的模型简化、网格划分等等相关操作后分析其元部件的应力应变的变化情况，最后得到该三维建模后的液压支架的不同工况下不同零部件受到的应力、载荷等的应力云图。通过对应力云图的相关分析，最终得到液压支架在设计以及受力分析时需要特别注意的有效意见。
本文是以有限元分析和系统建立液压系统为基础的现代设计方法的实际应用，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有一定的应用的意义。

Design and finite element analysis of hydraulic support
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 complete three-dimensional modeling. finite element analysis software ANSYS, and then will be after the completion of the three-dimensional entity model into ANSYS, to carry on the related model simplification, meshing and so on related operations, finally get the 3D modeling of hydraulic support under different working conditions of different parts of stress nephogram of stress, load, etc. Through the correlation analysis of stress nephogram, finally get hydraulic support need special attention during design and stress analysis effectively.
This article is based on finite element analysis and system to build hydraulic system of the practical application of the modern design method, the complete design of hydraulic support has a certain meaning, to solve the problem of related engineering knowledge has a certain application meaning.
Key words: Hydraulic Support; Hydraulic System; Three-dimensional modeling; Finite Element Analysis; ANSYS
