Title
(EN) BALANCE SCALE FOR TESTING AIR RESISTANCE
(FR) BALANCE PERMETTANT DE TESTER LA RÉSISTANCE À L'AIR
(ZH) 空气阻力测试天平
Abstract
(EN) A balance scale for testing air resistance, comprising: 2N dual-hole beam sensors and an upper plate; the 2N dual-hole beam sensors are arranged below the upper plate and are fixedly connected to the upper plate; each dual-hole beam sensor comprises a beam part, an upper hole and a lower hole, the upper hole and the lower hole being longitudinally arranged along the beam part, the upper hole being arranged at an upper part of the beam part, and the lower hole being arranged at a lower part of the beam part. Further disclosed is a method for measuring the friction of an upper surface of the upper plate by using the balance scale for testing air resistance.
(FR) La présente invention se rapporte à une balance qui permet de tester la résistance à l'air, et qui comprend 2N capteurs de faisceau à double trou et une plaque supérieure. Les 2N capteurs de faisceau à double trou sont placés en dessous de la plaque supérieure et reliés à demeure à cette plaque supérieure. Chaque capteur de faisceau à double trou comporte une partie faisceau, un trou supérieur et un trou inférieur, le trou supérieur et le trou inférieur étant disposés longitudinalement le long de la partie faisceau, ledit trou supérieur étant agencé à l'emplacement d'une partie supérieure de cette partie faisceau, et ledit trou inférieur étant agencé à l'emplacement d'une partie inférieure de cette partie faisceau. La présente invention a trait en outre à un procédé qui sert à mesurer le frottement d'une surface supérieure de la plaque supérieure à l'aide de la balance permettant de tester la résistance à l'air.
(ZH) 一种空气阻力天平,包括:2N个双孔梁传感器,以及上板;2N个双孔梁传感器配置在上板的下方,并与上板固定连接;每个双孔梁传感器包括梁部、上孔和下孔,上孔和下孔沿梁部的纵向配置,上孔配置在梁部的上部,下孔配置在梁部的下部。还公开了一种使用空气阻力测试天平对上板的上表面的摩擦力进行测量的方法。
