基于大涡模拟的高速电梯轿厢气压变化规律
Air Pressure Change Rule of High-Speed Elevator Car Based on Large Eddy Simulation
摘要
Abstract
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.关键词
