摘要
电梯是高层建筑必不可少的垂直交通工具,乘坐舒适度逐渐成为民众关注焦点.针对乘坐电梯产生耳鸣的问题,基于智能手机气压传感器、加速度传感器和物理实验应用程序phyphox,对高层建筑电梯运行物理特性进行研究,结果表明电梯运行速度和加速度过大,导致气压的变化幅度及变化速率超过阈值范围,导致部分耳膜较为敏感住户产生耳鸣现象。根据实验结果调整优化电梯运行参数以后,乘客耳鸣问题得到解决,体现“从生活走向物理,从物理走向社会”。
Elevators are vertical means of transportation in high-rise buildings,and ride comfort has gradually become the focus of public attention.Aiming at the problem of tinnitus in elevators,based on the smartphone air barometer,accelerometer and physics experiment application phyphox,the physical characteristics of high-rise building elevator operation are studied.The results show that the elevator operation speed and acceleration are too high,which leads to the amplitude and change of air pressure.The rate exceeds the threshold range,causing tinnitus in some residents with sensitive eardrums.After adjusting and optimizing the elevator operating parameters according to the experimental results,the problem of passengers’tinnitus was solved,which was called“from life to physics,from physics to society”.
