液壓支架的动态特性分析.docVIP

摘 要 液压支架是地下工程或隧道工程的关键设备之一，它主要用于支护顶板、防止顶板垮落，为施工人员和施工设备提供一个安全可靠的工作空间。 在分析了传统液压支架架型的基础上，通过机构演化，研究了一种新架型——垂直导杆型液压支架；该新型支架不仅结构简单、重量轻和调架容易，而且可极大地改善液压支架的受力状况，提高稳定性，具有广泛的应用前景。 然后，用三维参数化的设计软件Pro/E，完成了垂直导杆型液压支架的三维参数化造型，实现了Pro/E与ADAMS软件之间的模型转换，并利用ADAMS软件对该液压支架进行动态分析，得到了该支架在工作状态下的承受载荷。 本文系统地研究分析垂直导杆型液压支架新架型，并采用现代设计技术和方法进行设计，缩短了液压支架的研发周期，提高了产品质量，降低了成本，对今后的液压支架产品的研究与开发具有指导意义和参考价值。 关键词：液压支架；垂直导杆机构；三维参数化；虚拟样机；动态特性 Abstract Hydraulic power support used in the underground engineering or tunnel project is one of important equipments, it is mainly used for supporting roof, preventing the roof from collapasion, providing a safe working space for both the workers and the equipments in the underground. On the analysis of the traditional hydraulic power support types, through the institution evolution, a new frame type--vertical guide bar type hydraulic power support; The new stents not only simple structure, light weight and the frame easy, and can dramatically improve hydraulic power supports stress situation, and improve the stability, and has a broad prospect of application. Then, use three dimensional parametric design software Pro/E, the completion of the vertical guide bar type hydraulic power support 3D parametric modeling, realize the model transformation from Pro/E to the ADAMS software, and then obtain the dynamic analysis of the hydraulic support in the ADAMS software. This paper analysis the vertical guide bar type hydraulic support new frame type, and adopts the modern design techniques and methods to carry on the design, shorten the development cycle of hydraulic support, improve the product quality, reduce the cost and for future hydraulic support product research and development with the instruction meaning and reference value.
