| The prop is the main load and height adjustment parts of the hydraulic support. Its performance will directly affect the use and reliability of the hydraulic support, thereby affecting the safety and production efficiency of the whole integrated coal face. Currently, both domestic and international put more emphasises on the development of the hydraulic support, but relatively little research on the prop.The prop is designed by handwork regularly with a long design cycle and heavy work intensity. Faced with the increasingly fierce market competition, it has a higher demand for the quality and cycle of the prop.Therefore, it already has a certain significance that we develop the system which can design and analysis the prop fastly by applying the CAD/CAE technology to the design of the prop.We take the necessary introduction to the hydraulic support, including the overall structure, working principle, domestic and international development status and future development trends.At the same time, we take a more detailed elaboration about the intensity calculation method of the double telescopic, UG secondary development and finite element analysis.According to the drawings of ZT/SLJ400a double telescopic,we establish the three-dimensional model of the prop as a template with UG, For achieving its parametric modeling, UG is taken a secondary development with UG secondary development tools such as OpenGrip, Open API, MenuScript and UIStyler.In accordance with MT312-2000 standards and European standards,we take the finite element analysis to all parts of the prop, especially the cylinder and guidance sets for four options.we can get the corresponding strength results and stresses distribution of the dangerous regional. The results and the stresses distribution are taken as the guidance to the design of the prop.UG has a high degree of parametic and a good relevance.The link of the parametic modeling and the finite element analysis can be achieved through some necessary settings, and the parametic system of the double-telescopic is finished.Through the development of the parametric system for the prop, the parametric design and finite element analysis can be achieved conveniently. The results of finite element analysis can be used to judge the success of the designed prop, and it is also as a guidance for the further design and optimization of prop.The efficiency and quality are improved. |
