门座起重机回转、变幅联合动作时各机构最佳速度的确定

An Optimal Determination on Working Velocity at ConcurrentWork Conditions of Swing and Derricking Mechanism

从优化的角度研究了门座起重机回转机构和变幅机构联合动作时起升、变幅和回转三大机构工作速度最佳值的确定．研究结果表明，选择最佳工作速度进行联合动作工艺对提高机械生产效率具有重要意义．

オhe paper Proposes an optimam on the hoisting ,swing and derricking velocity of portal cranes at concurrent work conditions.The result shows that the selecting optimum working velocity for concurrent work of swing and derricking mechanisms will improve its productivity.
