Analysis And Control Of Certain Mining Equipment To The Mechanical Hydraulic System

With the rapid development of the Chinese railway and its increase of carriage amount by railway, mechanical technology in field of Railway maintenance is developed faster and faster. Designing and researching technical methods now are too low in efficiency and too high in cost to fit the economy development and marketing competition. Instead of physical prototype experiment, Virtual Prototype Technology is of great meaning in shorting product developing cycle, lowering researching cost, improving design quality and product performance.In this paper, current situations of Screen scarifier for both civil and aboard, classify and working parameters of Screen scarifier and develop of virtual technology are analyzed firstly. A right digging structure of a ballast shouder cleaning machine is taken as researching object, analysis and discussion are done about if ’dead point’ issue occurs, performance of its mechanical structure and mechanical hydraulic coupled system, based on which, an appropriate precept is selected after comparing other four precepts.Three-dimensional models of the structure are modeled and assembled in UG software firstly; secondly, models are imported into ADAMS software to finish virtual prototype. The working requirements are met from the structure’s smooth work, no obvious break in loading condition and no ’dead point’ occurrence, which is reflected by the performance out of the dynamic analysis of mechanical structure. Thirdly, the hydraulic system is analyzed. Co-simulation between mechanical system and hydraulic system is done by software interface after hydraulic system model is simulated by AMEsim software then. Results of co-simulation and dynamic analysis from ADAMS are compared, which make accuracy of co-simulation modeling and co-simulation method believable. Evaluation of hydraulic system is also done. At last, combined the research with practical situation, four mechanical structures are proposed. Comparisons are done with the original precept, an optimized precept is brought out.The fuzzy control and Screen scarifier excavation institutional analysis, the propose a Screen scarifier digging chain guides of mathematical model, we design a gravity compensation fuzzy PD controller that combines the advantages of gravity compensation PD control with those of fuzzy control and then introduce the fuzzy PD controller into Screen scarifier digging chain guide groove. The simulation results show that, compared with the traditional PD controller, the gravity compensation fuzzy PD controller can improve the dynamic performance of the digging chain guide groove, effectiveness and produce a better robustness.In this paper, advanced three-dimensional modeling, virtual prototype technology and co-simulation technology are introduced to analyze and optimize the digging structure of ballast shouder Screen scarifier. A study conducted for the slope Screen scarifier mining institutions and similar institutions as well as product design and development to provide a new effective way; Screen scarifier digging chain guide groove, with some guidance and engineering application value.
