Abstract
The deflections of throttle slices were analyzed and the equivalent relations of flux distribution were deduced according to the structure of self-designed hydro-pneumatic spring. The flux coefficients of control valve were fitted by the least squares method under different current strength, and combining with the state equation of real gas, the mathematical model of hydro-pneumatic spring with controllable damping was built. The relations between the total export force and the displacement were analyzed under different current strength, and the correctness of model was validated through comparing with the experimental data. The field tests of hydro-pneumatic suspension with controllable damping were carried out on different roads, which offer reference to design new products.
