摘要
考虑提升系统横向和纵向的耦合作用。应用广义Hamliton原理建立了带有张紧补偿钢丝绳的高速电梯提升系统振动控制方程,并以高速电梯提升系统为例对模型进行了数值仿真分析。结果表明:张紧装置的增加能有效抑制提升系统振动,一方面从理论上分析和解释了具有张紧装置的补偿钢丝绳可以大大减小提升系统振动的原因,另一方面说明选择张紧装置抑制提升系统振动的合理性,研究工作为下一步高速电梯提升系统振动控制器的实际应用提供了具有建设性的方法及其思路。
The governing equations of the high-speed elevator hoisting system with a tensioning device were developed employing the generalized Hamlton , s principle considering the horizontal and vertical motion coupling effect. The motions of the high-speed elevator hoisting system were illustrated to evaluate the proposed mathematical model and solution method. The simulation results show that the tensioning device can effectively control the vibration of the hoisting system. The reasons that the vibration of the hoisting system can be greatly reduced by the compensating rope with tensioning device were analysed and explained. It is also shown that the choice of the tensioning device is reasonable to suppress the vibration of hoisting system. The results provide a constructive way and idea for the practical application of vibration controllers.
