摘要
针对大型全回转浮式起重机的结构和工况特点,在满足抗倾覆稳定性要求下,将浮式起重机自重产生的不平衡力矩与起升货物产生的不平衡力矩之和的均方根力矩作为目标函数值,建立以平衡系统主要构件强度、刚度、结构尺寸和回转轮压合理性为约束条件的多目标设计优化数学模型,运用遗传算法优化浮式起重机平衡系统,最终得出优化数据.该数学模型在具体优化过程中取得较为满意的优化结果,为大型全回转浮式起重机的设计优化提供有效方法.
As to the structure and working characteristics of large floating crane with full rotation,a mathematical model for multi-object design optimization is established to meet the request of overturning stability.The objective function value is the root mean square torque of the sum of unbalanced moment generated by crane weight and lifted cargo.The strength,rigidity and structure size of main components and rotary wheel pressure rationality are taken as the constraint conditions for the balance system.The genetic algorithm is used to optimize the floating crane balance system.And the optimization data is obtained.The mathematical model achieves better optimization effect,which is an effective method for the design optimization on the balance system of floating crane.
