摘要

摘要: 提出了一种分析核环吊系统吊重轨迹偏差的系统化方法——平衡路径法,给出了平衡路径方程和协调条件,并详细讨论了方程中所涉及的各种变量的性质和计算方法；考虑了动滑轮位置改变所引起的钢丝绳拉力方向的变化,提出了确保与钢丝绳绕绳方式一致的空间滑轮公切线求解方法；给出了卷筒卷入绳长、钢丝绳分支中绳长的计算方法,以及滑轮两端绳速传递关系。这些问题的解决方法具有一定的普适性,可应用于一般滑轮绳索系统。

Abstract: A systematic method for analyzing load trajectory deflections of nuclear ring cranes was presented, including the governing equations of equilibrium paths and their compatibility conditions. Properties and formulations of the variables involved in these equations were studied in detail, in which the variation in pull directions of ropes with positions of pulleys was taken into account and a numerical method was derived to ensure the roping manner conforming to the common tangent of two pulleys. Moreover, we also provided a method to compute rope lengths wound by the drum and between two out rope points on pulleys, and the transitive relation for rope velocities between two ends of the pulley was derived. To a large extent the proposed method is universal and can be applied to general rope-pulley systems.
