【Abstract】 The Virtual Design and Simulation Study of Self Propelling-locating System is a part of the Visual Virtual Design of the Milling-drilling Special-purpose Machine Tool Stepped Processing Overlength Workpiece’ s Surface. The Visual Virtual Design of the Milling-drilling Special-purpose Machine Tool Stepped Processing Overlength Workpiece’ s Surface is a research task to solve the processing problem of the 16 meter-length faying surface fixing water-tight blukhead of the water sluice gate of the LongTan Hydroelectric Power Station in Guangxi. It is a very significant work academically, and it will bring a lot of economic and social benefit.Some modern design means, such as the Computer Aided Design, the Computer Aided Engineering, the technique of virtual design, the technique of simulation, are used, as a result, the design of the Self Propelling-locating System is reliable. The mathematical models of the synchronous hydraulic system which includes four hydraulic cylinders are built by means of the power bond graphs, which will become the basis of simulation and majorization of the hydraulic system. The design flow process chart of the Self Propelling -locating System is built in the thesis, which is valuable for the design of other machine facilities.更多还原
