建立了钢丝绳两端均装有张力自动平衡装置（TABD）的平行提升系统纵向振动模型，并基于汉密尔顿原理推导了该模型的控制方程。Galerkin的努力被施加到离散的无穷维偏微分方程成一组有限维常微分方程，使该模型可以用数值解求解。随后，进行了亚当斯仿真，仿真结果验证了数值解的有效性。因此，为了研究这两个提升绳的纵向响应，该模型进行了数值计算与不同的系数和激励。数值计算结果表明：对于所有提升钢丝绳末端均装有TABD的平行提升系统，输送力是影响钢丝绳纵向振动的主要激励，系统加速度也会引起钢丝绳产生较大的纵向振动。
The longitudinal vibration model of parallel hoisting system with tension auto balance device (TABD) attached to the ends of all hoisting ropes is established, and the governing equations of the model are derived based on Hamilton’s principle. Galerkin’s effort is applied to discretize the infinite-dimensional partial differential equations into a set of finite-dimensional ordinary differential equations, so that the model can be solved with numerical solutions. Subsequently, an ADAMS simulation is carried out, and the simulation result has verified the validity of the numerical solution. Consequently, in order to investigate the longitudinal responses of the two hoisting ropes, the model is calculated numerically with different coefficients and excitations. The results of the numerical solution have shown that: For the parallel hoisting system with TABD attached to the ends of all hoisting ropes, the conveyance will be the main excitation that affects the longitudinal vibration of the ropes, and the system acceleration will also cause a relatively large longitudinal vibration in the ropes.
