| Abstract: | Geometric deviation of top side rail after sidewise bending,which frequently occurrs during the production of the steel-structured car body for P70 boxcar is analyzed and the causes are pinpointed.By implementing restraint welding and dimensional modification of the camber beam on roof,the sidewise bending process of the top side rail is now up to specifications. |

| Keywords: | top side rail sidewise bending geometric deviation process measure |
