| Abstract: | Aiming at nonlinearity of servo valve controlled asymmetric hydraulic cylinder system, the bond graph model of valve controlled asymmetric cylinder position system is built, according to the working principle of hydraulic system and the modeling theory of power bond graph. The veracity of bond graph model is proved by comparing simulation data and test results. The analyzing system model is able to provide theoretical foundation for improving system performance. |
