板弹簧在机车车辆上起着缓冲吸振的柔梁作用,它承受弯曲应力,极易疲劳。由于它的性能和作用决定了弹簧板的表面不允许有髪纹和裂纹。因此,新造和检修板弹簧时,必须注意检查其表面质量情况。目前,我国机车车辆工业部门已广泛采用电磁探伤来检查板弹簧的表面质量。我厂在检修蒸汽机车时,对导、从、煤、动轮板弹簧均采用电磁探伤,首
Plate spring in the rolling stock car shock absorbing vibration of the role of flexible beams, it withstand bending stress, fatigue. Because of its performance and role of the decision spring plate surface does not allow streaks and cracks. Therefore, new and maintenance plate spring, we must pay attention to check the surface quality. At present, China’s rolling stock industry sector has widely used electromagnetic detection to check the surface quality of leaf springs. I plant maintenance steam locomotive, the guide, from, coal, moving wheel springs are used electromagnetic detection, the first
