在假设振动索段保持悬链线形状的情况下，分析了天际线测井索系统典型索段的自由振动和强迫振动，推导了实现拉格朗日运动方程的能量表达式。将该方法的结果与该资深作者博士论文中发表的有限差分结果进行了比较，并讨论了该方法应用于更复杂电缆结构的准确性和实用性。
The free and forced vibrations of cable segments typical of a skyline logging cable system are analyzed by assuming that the vibrating cable segment maintains a catenary shape, and energy expressions are derived to implement the Lagrange equation of motion. The results of this method are compared with finite-difference results published in the senior author’s PhD thesis and the accuracy and usefulness of the approach applied to more complex cable configurations are discussed.
