双比载放线曲线仿真模拟

结合张力放线中不同比载线索在同一档内过渡曲线的研究,提出以悬链线法为基础的精确计算模型, 过渡模型以双比载放线曲线联接处切线斜率K 为研究对象, 确定K 的变化范围Kmin, Kmax] ,其具体数值只对应于相应比载, 且为单调增函数。通过给定K 值下的平移曲线、平移坐标轴完成静态模拟, 然后控制斜率K步长完成Kmin, Kmax]区间的动态模拟过程, 并建立完整的模拟图形, 有助于对具体施工情况的认知。

Simulation of Dual Specific Load Stringing Curves

By studying transition curves of cables with different specific loads within same span under stringing operation,a precise calculation model based on Catenary method is presented.By using the slope of the jointing point of dual specific load string curves,K,as study object,the transition model determines the range of K,Kmin,Kmax],with its actual value only depends on corresponding specific load and is monotonically increase.By shifting curve and coordinate axes under given K,the static simulation can be performed.Then,by controlling step of slope,K,the dynamic simulation within Kmin,Kmax] range can be accomplished.Finally,the complete simulated graph is established.
