| 摘 要： | 集装箱正面吊变幅机构是正面吊大臂举升机构的核心，其变幅铰点位置的确定直接影响到整机的性能。通过对变幅机构受力特性的分析，以变幅油缸最大负载最小及变幅液压系统液压冲击最小为优化目标，建立变幅机构三铰点数学模型，采用分层排序法处理多目标问题的优化，利用Matlab粒子群算法对变幅铰点位置进行优化，结果表明优化后的铰点位置提高了正面吊整机性能，为变幅机构参数设计和改善提供了重要依据。

| Abstract: | The luffing mechanism of reach stacker is the core of arm luffing mechanism. Therefore, the hinge point＇s positions of leveling mechanism directly affects the whole performance. Through the force analysis of luffing mechanism, a mathematical model of three hinge points is established,which aims to reduce the max force of oil cylinder and decrease the oil pressure of oil system. The paper deals with multi-objective optimization problem by using hierarchical ordering method. The optimization calculation is presented by using the particle swarm optimization of Matlab. The results indicate that the optimized result can enhance the performance of the reach stacker. |
