According to AAR Manual,calculations are made respectively for the lateral forces applied on vehicles due to deviation of the coupler while the drawing point is in different positions(on the bogie and on the carbody) of the new type speed increased 90 t depressed center flat car,so that basis is provided for determination of the overall scheme.
按照《AAR机务标准手册》,对新型提速90 t凹底平车的牵引点布置在不同位置(布置在转向架上和布置在车体上)时由于车钩的偏移而作用在车辆上的横向力分别进行了计算,为确定总体方案提供了依据。
