Abstract

Abstract

Based on the structure and its condition of the main bolt of RPV, this paper puts forward a kind of clipping peak and averaging load structure of the thread, which can equal the load distribution of thread connection.Meanwhile, the mathematical model of bigbolt thread Connection is set up. By using the finite element analysis function, Compare with ordinary screw thread the feasibility of averaging load structure of the thread is validated. This thread structure can eliminates the main bolt gluing and improves the safety, reliability and longer life of the thread connection for the RPV.
