摘　　要：针对高端气液增力缸的研发问题,以德国TOX公司S8.30.200.12型号气液增力缸为代表研究对象,分析了该气液增力缸的结构、工作原理以及数学模型,利用AMESim完整的搭建出该气液增力缸仿真模型,得到了气液增力缸冲压特性曲线与压差换向阀延时换向特性曲线。模拟得到的冲压特性与参考值、实验值误差在5%之内。此外,力行程转换阀的特性曲线准确的反应了气液增力缸延时特性,为国内高端气液增力缸的研发起到一定的推动作用。Aiming at the development of high-tech gas-liquid booster cylinder,we analyze the structure,the working principle and the mathematical model of the gas-liquid booster cylinder by taking the German TOX company's S8. 30. 200. 12 model as the representative. Using AMESim to build the gas-liquid booster cylinder simulation model,we obtain the stamping characteristic curve of gas-liquid booster cylinder and the delay-commutation characteristic curve of differential pressure reversing valve. The simulated stamping characteristic error is within 5% of the reference and the experimental values,which reflects the reliability of the simulation model. In addition,the characteristic curve of force stroke conversion valve accurately reflects the delay characteristics of gas-liquid booster cylinder,and plays a certain role in the development of the domestic advanced gas-liquid booster cylinder.
