| Abstract: | To study the mechanical properties of connective component of bolt group, the representative bolt group connective component of a high speed train is taken as the study object, the preload force is loaded on it by using nonlinear finite element contact algorithm and equivalent preload method, and the connective component is simulated under different preload of bolts and bolt position. The stress around hole is compared, and the optimal bolt position and preload are obtained. |

| Keywords: | bolt group connective component preload bolt position contact |
