The working principle of twinroller machine is introduced in this paper. The functional requirements of the hydraulic system and the high pressure problem of the hydraulic cylinder were described. In order to simulate roll gap increase in the working condition,the hydraulic system model is established by AMEsim software.The simulations is carried out at different precharge nitrogen pressures and different accumulator volumes. The relationship between the precharge nitrogen pressure,accumulator volumes and the cylinder pressure by analyzing were obtained. And the optimal parameters were obtained. The optimization work provides theoretical data for the modification of machine.
