| Abstract: | General situation of hydrocracker machines is introduced. It is know through calculation of the broken bolt in second stage cylinder that the stress amplitude safety factor of the broken bolt is smaller than the safety value, the cause for bolt breakage is found through analysis, and it is known that the stress amplitude safety factor of the replaced bolt is greater than the safety value. |

| Keywords: | general situation of machines causes for bolt breakage stress amplitude safety factor |
