摘要: 为分析影响减摇效果的主要因素和关键参数,根据液压减摇系统的结构、小车吊重系统的运动特点和工程需要,建立了简化的系统动力学模型.仿真研究表明,起升绳长不变时,液压减摇系统结构参数和起升载荷是影响减摇效果的关键参数和主要因素;当起升质量(或结构参数)一定时,减摇系统的减摇效果取决于结构参数(或起升质量);系统的最佳结构参数与载荷的比值的范围为1.6~2.0 s-1.Abstract: To analyze the main factors and key parameters affecting the performances of the hydraulic anti-sway system for container cranes,simplified system dynamic equations were derived to meet practical requirements on the basis of structural characteristic of the anti-sway system and its trolley-load system.Simulation results show that structural parameters and hoist load are the main factors affecting the performances of the anti-sway system for a certain length of hoist rope;the performances depend also on structural parameters(or hoist mass) when the hoist load(or structural parameters) is/are known;and the optimal ratio of a generalized structure parameter to the hoist mass is in a range of 1.6-2.0 s-1.
