随着城市化的快速发展和现代城市中人口不断增长,现代城市的建筑越来越多地向高层、超高层发展。这些建筑中,电梯已成为必不可少的代步工具。随着电梯的广泛使用,人们对于电梯乘坐舒适性的要求也越来越高。本文从系统受迫振动理论出发,导出了绕绳比为1:1的装有轿厢动力减振器的电梯系统动力学模型,并从理论上证明了可以使用多个不同固有频率的减振器来抑制多个不同频率的垂直振动。
With the rapid development of urbanization and the continuous increase of population in modern cities, the modern city’s buildings are increasingly developing to the high and super high-rises. In these buildings, elevators have become an essential means of transportation. With the extensive use of elevators, people are increasingly demanding the comfort of elevators. Based on the theory of forced vibration of the system, this paper derives the dynamic model of the elevator system equipped with a car dynamic damper with a 1:1 ratio of roping, and theoretically proves that it is possible to use multiple natural frequencies for vibration reduction. To suppress vertical vibrations at multiple different frequencies.
