| Abstract: | The cylindrical helical spring is a key component of a mechanical transmission system, and its reliability directly affects the stability and security of the structure. The actual loading conditions of the cylindrical helical spring Engineering is analyzed. Then the stiffness and strength are theoretically checked based on mechanical design rules. Finally, the fatigue lifetime of most dangerous node is found for the spring by simulation using MSC Fatigue. The results show that the design fatigue lifetime of the spring can meet the fatigue reliability requirements. |
