| Abstract: | The air cylinder bolts of super high pressure compressor may get fatigue failure after by action of the alternating loads. The analysis methods of fatigue life to the air cylinder bolts are introduced,the fatigue life can calculate according to the rate of crack growth and critical flaw size of bolt material. It provide a reasonable basis to the equipment maintenance. |
