ANSYS was used to make finite element analysis and optimization for super high pressure bolt tensioner. Aiming at the critical section,safety factor assessing and strength checking were done. According to the ASME specified testing pressure,the optimized structure was checked again. For getting the equipment safe operation coefficient,fatigue analysis was done for bolt tensioner, which provided safety basis of equipment.
