| description | <b>[Objectives]</b> Bolt is usually used in connection for titanium alloy bulbous bow domes of new types of ships and such connection is exposed to bow slamming and wave loading,thus fatigue analysis of titanium-steel connection structure is necessary.<b>[Methods]</b> The finite element method is used to make stress analysis of the titanium-steel joint for new ships,and the stresses of titanium-steel connection bolts are calculated. The fatigue cumulative damage theory and <i>S-N</i> curve method are used to calculate the fatigue life of titanium-steel connection. According to the stress analysis of titanium-steel connection of ship,the fatigue test plan is formulated accordingly to conduct fatigue test on titanium-steel connection.<b>[Results]</b> The results show that the theoretical calculation of fatigue strength of titanium-steel connection of new type of ship is largely consistent with the test results and the method for the fatigue analysis of titanium-steel connection is reasonable.<b>[Conclusions]</b> This paper established a method for research on fatigue strength of titanium-steel joint,and the study results can be used for the titanium-steel connection type,bolt type selection and optimization and can provide a useful reference. |
