摘　　要：采用SACS软件对半潜式生产平台进行整体提升模拟,对于采用液压系统的提升系统,基于力-变形曲线的非线性模拟方法更精确地模拟提升系统的钢绞线受力情况,根据液压提升系统实际刚度对整体提升系统进行非线性计算,此方法可准确模拟单个吊点处多个液压提升器的钢绞线受力情况,计算结果与实际情况情况相符。The SACS software is used to simulate the topside integration of semi-submersible production platform by super-lift method.A nonlinear simulation method based on force-deflection is used to simulate the loading condition of the steel strands more accuracy with regarding to hydraulic lifting system.According to the actual stiffness of the hydraulic lifting system,the nonlinear calculation of the overall lifting system is carried out.The stress of the steel strands of multiple hydraulic elevators at a single lifting point could be accurately simulated,and the results are consistent with those at the actual loading condition.
