随着我国国民经济的迅速发展和科学技术的不断进步,铁路机车牵引力在不断加大,列车运行速度和密度不断提高,铁路系统因此面临许多行车安全的课题,对安全设备提出了更高的要求。例如,无论铁路车辆还是机车,其车轴都在高速运转过程中产生热轴现象,这是关系到行车安全的因素之一。如果不能检测出车轴的温升,并控制在规定的范围内,轴承就会因无法承受高温而发生燃轴和弯曲变形,严重时将造成行车事
With the rapid development of our national economy and the continuous improvement of science and technology, the tractive power of railway locomotives is continuously increasing, and the speed and density of trains are continuously increasing. As a result, the railway system faces many traffic safety issues and places higher demands on safety equipment . For example, whether a railway vehicle or a locomotive has its axles generating a hot shaft during high-speed operation, it is one of the factors that contribute to driving safety. If you can not detect the temperature rise of the axle, and control within the specified range, the bearing will be unable to withstand the high temperature and combustion shaft and bending deformation, will cause serious driving things
