利用ANSYS软件对60 t-63 m岸边集装箱起重机进行轻量化设计,在保证刚度和强度满足要求的条件下,优化后结构质量比之前减少了3.56%。为计算由于测量误差等各种随机因素造成的结构失效概率,利用ANSYS软件概率分析功能对优化后结构进行可靠性分析,确定优化后结构的失效概率和应力、应变的均值分布曲线。从应力、应变对于各输入变量的灵敏度分析中得知,结构失效最敏感的参数是海侧立柱各板厚度。将优化设计和可靠性分析技术相结合,为以后的工程设计提供了一种分析方式。
The lightweight design of the 60 t-63 m shore container crane using ANSYS software reduced the mass of the optimized structure by 3.56% compared with the previous one, while maintaining the required stiffness and strength. In order to calculate the probability of structural failure due to various random factors such as measurement error, the reliability analysis of the optimized structure is performed by using the probabilistic analysis function of ANSYS software to determine the failure probability and the mean distribution curve of stress and strain of the optimized structure. From the sensitivity analysis of stress and strain to each input variable, we know that the most sensitive parameter of structural failure is the thickness of each plate on the sea side column. The combination of optimization design and reliability analysis technology provides an analytical method for future engineering design.
