目前，工作面支护问题始终是围绕煤矿生产安全、质量、效率的重要问题。高产高效综采工作面正向“设备重型化、工作面大型化”的方向发展，我国许多大型煤炭能源集团公司也正在发展超大型综采工作面，对液压支架的需求量日益增加，因而对液压支架设计水平的要求愈来愈高。本文旨在将数字化样机技术应用于液压支架的设计分析，以此改进液压支架的设计分析手段，提高设计效率和设计质量。 本文在阐述国内外液压支架和数字化样机技术的研究现状和发展趋势的基础上，论证了将数字化样机技术应用于液压支架设计和分析的必要性与可行性；依据孙家岔煤矿的地质条件和预定生产能力，进行了液压支架的选型、总体结构和主要参数的确定，并对其工作过程进行了分析；利用CATIA软件完成了ZY8700/17/32型液压支架的三维实体模型，经过虚拟装配，建立了液压支架的数字化样机；通过对数字化样机的三维可视化动态模拟、干涉检查和运动学分析，验证了所建立的数字化样机的正确性。再将三维实体模型导入到ADAMS中进行运动学和动力学分析，为液压支架的设计和研究提供一种行之有效的方法。所得结论对液压支架的设计分析和性能评估具有参考价值，也为其他复杂机械设备的运动学、动力学分析和建立数字化样机提供了借鉴意义。由于液压支架数字化样机的研究是一项长期、复杂、艰巨而细致的工作，本文的研究工作仅仅是对其进行探索性的研究。

Currently, face support is the important issues centered on coal production safety, quality and efficiency in China. The developing tread of high-yield and high-efficiency top foreign mining face is heavy equipment and large face. Many of our large coal energy corporation is currently developing super fully mechanized coal face, which demands increasingly on the hydraulic support with high performance. This paper seeks to analyze and design the hydraulic support based on digital prototyping technology to improve the designing and analytical tools, and enhance design efficiency and quality. It described the status quo and development trends of the hydraulic support and digital prototyping technology, and demonstrates the necessity and feasibility that uses the digital prototyping technology to analyze and design hydraulic support. Based on the geological conditions and scheduled production capacity in Sun Jiacha coal Co., Firstly we put our eyes on the selection of hydraulic support, overall structure, main parameters, and the analysis of its process. Secondly in examining the hydraulic support (ZY8700/17/32) equipment movement，the device 3D model is constructed on CATIA software, and a virtual prototype of hydraulic supports is established after virtual assembly. It verifies the establishment of the virtual prototype is correct by 3D visualization of dynamic simulation, interference checking and kinematics analysis. Furthermore, the 3D solid model is put into the ADAMS for multi-body kinematics and dynamics analysis, which provides a known effective method for the design and research. The conclusion drawn by the right guidance devices physical prototype testing and performance evaluation has great reference value for hydraulic support and other complex mechanical equipment. As the hydraulic support virtual prototyping research is a long-term, complicated and arduous and painstaking work, this research is only on its exploratory research.
