Abstract

The three-element hydraulic converter as subject is investigated, dynamic mathematics model is established, and formulas of transfer function are deduced. The tests of hydraulic converter for gaining transfer function and dynamic characteristics are performed by using dSPACE real-time control system on the dynamic simulation test-bed. Thus the accurate and applied 4steps dynamic model of hydraulic converter is obtained on the unsteady operation conditions, at the same time the test curves are also contrasted with theoretical curves for validating accuracy. The result shows that 4 steps dynamic model has high quality and reliability. So it is significant to improve the dynamic loading calculation of hydraulic converter inner structure and the more studying dynamics of tracked vehicle transmission system.
