摘要

液压支架是综采设备的重要组成部分。由于我国机械行业目前对于产品的开发设计环节关注度远远低于国外同行业，从而导致产品设计效率低下，开发周期长，优化产品性能困难。为提高综采设备企业的国际市场竞争力，首先要缩短液压支架开发设计时间，以及提高液压支架的可靠性，并且通过对液压支架静力学的分析对其尺寸参数进行优化，保证设计的质量。

本文以四柱支撑掩护式液压支架为例，根据液压支架强度试验而模拟出井下各种危险工况的加载方式，分别对液压支架建立平面力学模型和空间力学模型的方法来对其进行静力学分析。不仅可以优化筛选液压支架的结构参数，而且还可以通过计算出来的关键部位的载荷来为后期的有限元分析做准备。

通过对Pro/E的TOP-DOWN和参数化建模技术的研究先对液压支架进行骨架建模，再使用发布几何、复制几何、参数—关系等方法来实现液压支架各零部件之间的信息传递和液压支架模型的建立。

基于Pro/TOOLKIT的开发方法，以Visual Studio 2005为集成开发环境使用VC++编程语言对Pro/E进行二次开发，以及对SQL Server数据库技术的深入研究。最后对模型库、力学模型、数据库等进行有机的结合，实现设计人员在特定的用户界面下快速有效地对液压支架进行设计和模型生成。[p1] 

本文的研究对提高产品的设计效率、缩短产品的开发周期有很高的实际应用价值，一定程度满足了现代企业在当今市场竞争中低成本高效率开发新产品的需求。

ABSTRACT

The hydraulic support is an important part of mining equipment. Because of Chinese machinery industry for attention of product development and design aspects is far lower than the same industry in foreign countries. It is resulting in inefficient product design and development cycles, optimize product performance problems, and it is difficult to reduce production costs through research and development. In order to improve the international competitiveness of the mining equipment companies, it is important to shorten the design time of the hydraulic support development, and improve the reliability of the hydraulic support, and optimize its size parameters by statics analysis of the hydraulic supports to ensure the quality of the design.

Using four-post support sheltering hydraulic support for instance. According to the strength test of hydraulic support which simulate the loading of the underground hazardous conditions to its statics analysis of planar mechanical model and space mechanics model of the hydraulic support. This not only can optimize the structure parameters of hydraulic support, but also the finite element analysis can be calculated from the critical parts of the load to prepare later.

Researching the Pro/E TOP-DOWN and parametric modeling techniques to model the hydraulic support, Using the skeleton modeling, publish geometry, copy geometry methods to realize geometrical parameters – relations between the various component s of the hydraulic support information transmission and hydraulic support model

Using VC++ programming language for development in Visual Studio 2005 integrated development environment. And in-depth study on the SQL Server database technology, in order to achieve a specific user interface, by which the designers can design and model a hydraulic support quickly and efficiently. Greatly improved the efficiency of the design and development of the hydraulic support.

This research to improve the design efficiency and shorten the product development cycle has a high practical value, in order to meet the needs of modern enterprises in today's market competition, cost-effective development of new products. cost-effective development of new products.
