Abstract:
      The finite analysis of the fatigue performance of the longitudinal rubber buffer component in the leg mating unit（LMU） used for the installation of the offshore oil platform by floating towing method was introduced.By establishing a thermal coupled fatigue calculation model，the fatigue failure and temperature rise of the longitudinal rubber buffer component was simulated.The results showed that the longitudinal rubber buffer component did not fail after being subjected to completing 2 200 cycles of loading during fatigue test，with a temperature rise of only 1.27 ℃，and the cyclic loading process was in a stable stress field cyclic state, meeting the engineering needs.
