High-speed elevator horizontal vibration seriously affects passenger comfort. To reach the smooth operation of the high-speed elevators, it is extremely important to study the horizontal vibration of the elevator car. There are two main factors that cause the horizontal vibration of the high-speed elevator car, namely, the guidance system excitations and the car aerodynamic characteristics running in the hoistway. Under the coupling action of these two factors, the horizontal vibration of the high-speed elevator car system is aggravated. To accurately obtain the horizontal vibration information of the high-speed elevator, we developed the high-speed elevator car horizontal vibration fluid–solid interaction model. It is decoupled by the proposed fluid–solid interaction decoupling solution. The influence of the high-speed elevator running speed, the guide rail profile deviation, and the rolling guide shoe dynamic parameters on the car horizontal vibration is analyzed. To verify the feasibility of the proposed method, the 5 m/s, 7 m/s, 8 m/s, and 10 m/s high-speed elevators are applied in a 288 m test tower. The simulation accuracy using the proposed method reaches the minimum of 0.93% in 5 m/s case of the peak-to-peak value, reaches the minimum of 3.11% in 10 m/s case of the A95 value, and reaches the minimum of 0.13% in 10 m/s case of the main frequency value. In general, the compared results of the peak-to peak vibration acceleration, the A95 value, and the main frequency are all closed in both 5 m/s, 7 m/s, 8 m/s, and 10 m/s cases.

高速电梯轿厢水平振动流固耦合建模方法

高速电梯横向振动严重影响乘客舒适度。为了达到高速电梯的平稳运行,研究电梯轿厢的水平振动是极其重要的。引起高速电梯轿厢水平振动的主要因素有两个,即导向系统激励和运行在井道内的轿厢气动特性。在这两个因素的耦合作用下,高速电梯轿厢系统的水平振动加剧。为了准确获取高速电梯的水平振动信息,我们开发了高速电梯轿厢水平振动流固耦合模型。它被提议的流固相互作用解耦解决方案解耦。高速电梯运行速度的影响,对导轨轮廓偏差、滚动导靴动态参数对轿厢水平振动的影响进行了分析。为验证所提方法的可行性,将5 m/s、7 m/s、8 m/s和10 m/s高速电梯应用于288 m试验塔。所提方法的仿真精度在峰峰值为5 m/s的情况下达到最小值0.93%,在A95值的10 m/s情况下达到最小值3.11%,达到最小值0.13% 在 10 m/s 的情况下主频率值。一般情况下,5 m/s、7 m/s、8 m/s、10 m/s情况下的峰峰值振动加速度、A95值、主频率的比较结果都比较接近。为验证所提方法的可行性,将5 m/s、7 m/s、8 m/s和10 m/s高速电梯应用于288 m试验塔。所提方法的仿真精度在峰峰值5 m/s情况下达到最小值0.93%,A95值在10 m/s情况下达到最小值3.11%,达到最小值0.13% 在 10 m/s 的情况下主频率值。一般情况下,5 m/s、7 m/s、8 m/s、10 m/s情况下的峰峰值振动加速度、A95值、主频率的比较结果都比较接近。为验证所提方法的可行性,将5 m/s、7 m/s、8 m/s和10 m/s高速电梯应用于288 m试验塔。所提方法的仿真精度在峰峰值5 m/s情况下达到最小值0.93%,A95值在10 m/s情况下达到最小值3.11%,达到最小值0.13% 在 10 m/s 的情况下主频率值。一般情况下,5 m/s、7 m/s、8 m/s、10 m/s情况下的峰峰值振动加速度、A95值、主频率的比较结果都比较接近。A95值10m/s情况下为11%,主频值10m/s情况下达到最小值0.13%。一般情况下,5 m/s、7 m/s、8 m/s、10 m/s情况下的峰峰值振动加速度、A95值、主频率的比较结果都比较接近。A95值10m/s情况下为11%,主频值10m/s情况下达到最小值0.13%。一般情况下,5 m/s、7 m/s、8 m/s、10 m/s情况下的峰峰值振动加速度、A95值、主频率的比较结果都比较接近。
