| Abstract: | According to standards of the International Welding Society and British Standards,with the finite elements static strength results and the actually measured load spectrum,the fatigue life comparison analysis is made for the modes of typical welded joints at key parts of an exported coal car body.The results show that the proper selection of modes of welded joints and welding technologies can double improve the fatigue life of structures. |
