Abstract

According to the existence problems of study on the mechanism of contact stiffness of bolted assembly structure formed by tightening sequence, a TK model of single bolt structure is established; then the frequency characteristics of combined surface under different TS was analyzed by using ANSYS; the optimal TS is obtained based on the frequency and the interface stiffness mapping. At last, a group of experiments was done to verify the above conclusions. The results show that the interface stiffness is verify under different TS, and so does the first rank natural frequency of the structure; the nonlinear response of the structure is significantly affected by TS that tighten at the same time is the optimal method compared with other TS. A small error of modal frequency between simulating and testing proves that the modeling method can effectively analyze impacts of the TS on the dynamic properties of the interface.
