Study on Collaborative Simulation Technique of Electro-Hydraulic Traction System with Large Inertia Flexibility Load

In Steel Grinding Machine, the hydraulic motor is needed to drive roller and the wire rope is needed to tow the huge steel billet to move back and forth in level track. The tow device is a kind of integrated system with hydraulic pressure, mechinary and controlling computer and the flexible wire rope makes the design of the system complicated and difficult. In order to make the systemetical scheme and operational quality optimized, the writer, in the paper put forward the advice that the multidisciplinary design and analysis software be utilezed to build the model and that the interface program be utilized to make a collaborative simulation and finish the technical route of the design. The research method can really and accurately obtain the load inertia flexibility of the wire rope and the load power, in the same time, in simulated calculation, a real-time consideration can be given to the effect of the parameters on controlling quality.Introducing the whole process in which AMESim and ADAMS are used to build a model for the system and make a collaborative simulation, the writer also contrasted the effects of the structure parameters and obtained the research result.
