| Abstract: |
| The work aims to conduct a numerical simulation study to investigate the change of ultimate load carrying capacity of the pin due to axial sliding wear in the marine environment, and to obtain the evolution of the ultimate load carrying capacity of the pin, so as to provide a theoretical basis for the safety assessment of the underwater wear structure. Firstly, ANSYS finite element analysis software was used to establish a "column-tile was established for wear analysis to obtain wear data under different axial sliding frequencies; Finally, the ultimate load carrying capacity of the pin under different wear depth (0/1/2/3 mm) was calculated, and its permissible ultimate load carrying capacity and the variation curve of cumulative use time with wear depth were obtained according to the mapping relationship of wear speed-wear depth-breakage force. Under typical operating conditions (sliding frequency of 3 Hz), the wear depth of the pin was up to 3 mm for about 3 298 h, and the allowable ultimate load carrying capacity decreased by 14 180 N. With the increase of the axial sliding frequency of the pin, the maximum wear depth, the total wear volume and the wear speed of the pin increase approximately linearly. Under typical operating conditions, the allowable ultimate load carrying capacity of the pin decreases linearly with the increase of service time, and the decreasing trend of the allowable ultimate load carrying capacity becomes slower with the increase of time. |
