| 为解决高速电梯运行时因轿厢内气压快速变化而严重影响乘坐舒适性的问题，课题组研究了高速电梯轿厢气压变化规律,建立了基于大涡模拟的高速电梯轿厢气压方程，制定了高速电梯轿厢气压变化的多因素仿真分析流程，分析了高速电梯运行速度、加速度、提升高度、通风孔面积和有无导流罩等因素对轿厢气压变化的影响，最后以某公司的KLK2型高速电梯为例进行了测试验证。实验结果表明：提升高度是引起高速电梯轿厢内气压变化的主要原因，运行速度、加速度等对轿厢内气压变化也会产生一定的影响。课题组的研究为高速电梯轿厢气压补偿设计提供参考。 |

| In order to solve the problem of severe impact on ride comfort caused by rapid changes of air pressure in the elevator car during high speed elevator running, air pressure change rule in high speed elevator car was studied. The air pressure equation of the high speed elevator car based on the large eddy simulation was established, and the multi factors simulation analysis flow of the air pressure change of the high speed elevator car was proposed. The influences of the high speed elevator car such as running speed, acceleration, lifting height, ventilation hole, whether install elevator shroud on the air pressure change of elevator car were analyzed, which were verified at KLK2 high speed elevator of a certain company. The experimental results show that lifting height is the major factor of the air pressure change in high speed elevator car. Running speed and acceleration will also impact on the air pressure change in the elevator car. The study can provide a reference for the air pressure compensation design of the high speed elevator car. |
