车轴是鉄路机车车辆最重要的零件之一。很久以来,它已成为疲劳研究的对象,并且在很多关于形状和应力对构件疲劳性能影响的资料中均已有所阐述。鉄路设计人员欲精确地确定车轴在运行情况下的载荷,必须考虑下列可能发生的载荷的复合作用: 1.由于车辆自重与载重所产生的静载荷; 2.由于车轮压装于车轴所产生的压力; 3.由于振动产生的动载荷; The axle is one of the most important parts of the Kushiro locomotive. It has long been the subject of fatigue research and has been described in many sources of information on the effects of shape and stress on the fatigue behavior of structural members. To accurately determine the axle load in the event of operation of the axle, designers must consider the following possible combinations of loads: 1. static load due to dead weight and load of the vehicle; 2. deadweight due to wheel press-fit on the axle Pressure; 3. Dynamic load due to vibration;
