自动伸缩门高度设计原则
Height design principle of automatic retractable door
●人们的审美习惯
● People's aesthetic habits
根据人们的审美习惯，通过平视进入人们视野的事物使人感到最舒服，仰视和俯视都达不到这样的效果。所以，自动伸缩门的高度设计也要遵循这一审美习惯，以防造成人们对其形成审美疲劳。
According to people's aesthetic habits, people feel most comfortable when they look at things that come into people's view, but neither look up nor look down. Therefore, the height design of the automatic retractable door should also follow this aesthetic habit to prevent people from forming aesthetic fatigue.
●力学原理
● Mechanical principle
自动伸缩门常常被安装于室外，不可避免地要经受雨淋、日晒、以及风吹。根据力学原理解释，自动伸缩门的高度越大，它自身抵御这些伤害的能力就越差，所谓“树大招风”，就是这个道理。自动伸缩门的高度越大，它接触的日晒面积，雨淋面积和风吹面积都会变大，加上高度高导致的重心上移，伸缩门对雨打风吹的抗击能力会明显下降
Automatic retractable doors are often installed outdoors, inevitably subject to rain, sun, and wind. According to the mechanical principle, the higher the automatic retractable door is, the worse its ability to resist these injuries is. This is the truth of the so-called "big trees attract wind". The higher the height of the automatic retractable door is, the greater the sun exposure area, rain drenching area and wind blowing area it contacts. In addition, the center of gravity moves upward due to the high height, the resistance of the retractable door to rain and wind blowing will be significantly reduced
