SIMULATION AND ANALYSIS OF HYDRAULIC LOOP BASED ON AMESIM
Abstract
With the development of present-day industry, it is demanded that the hydraulic transmission and control systems should have higher performance and control precision. The AMESim simulation software based on Power Bond Graph have a friendly interactive interface. It is convenient for using and can largely reduce the worklode and requirement of professional knowledge of workers, makes the users can modeling and simulate rapidly, analyse and improving the design, reduce the cost of exploitation and shorting design cycle.
The paper firstly introduce the foundation of fluid drive and modeling methods. Then introduce the function and characteristic of AMESim, modeling and simulation software for hydraulic and mechanical systems. Labor the application of main software AMESim with an instance of a surface grinding machine hydraulic actuator system. Lastly, the press jar loop and the drive motor loop hydraulic system of hydraulic pusher for long rail was simulated and researched separately with AMESim.
The simulation result of hydraulic pusher for long rail based on AMESim accord with the academic situation. It indicates: the method of numerical simulation is an effective approach to analyse the dynamic characteristic of hydraulic system. AMESim is a perfect choice to model and simulate for mechanic and hydraulic system, further more it can be used in the designing of hydraulic system to advance the efficiency and level of design.
