中文摘要：

假定液压硫化机的负载为200kN，设计的硫化机液压系统合模缸活塞直径和活塞杆直径分别为320和220mm，上模缸活塞直径和活塞杆直径分别为100和70mm，压力油管内径为12mm，吸油管内径为25mm，油箱容积为160L。采用液压系统建模与仿真软件AMESim进行额定工况的建模仿真，结果表明，所设计的液压系统具有足够的合模力，达到了设计要求。

英文摘要：

The load of the hydraulic vulcanizer was assumed as 200 kN,and the designed hydraulic system parameters were as follows： the piston diameter of clamp cylinder was 320 mm and its rod diameter was 220 mm; the piston diameter of upper mould section cylinder was 100 mm and its rod diameter was 70 mm;inner diameter of the pressure oil tube was 12 mm,inner diameter of the inlet oil tube was 25 ram,and the volume of the reservoirs was 160 L. This hydraulic system were modeled and simulated by AMESim software under normal conditions. The simulation results showed that the hydraulic system exerted enough clamping force on vulcanizer and satisfied design requirements.
