| Abstract: | The 3-Dimensional Geometry Model for the engagement between the gear and rack of the lifting System of offshore jack-up platforms is established with software Pro/Engineer and is put into software Abaqus to perform infinite element analysis on the dynamic engagement between the gear and rack. The contact stress and the change of stress on the tooth root during the dynamic engagement of gear and rack are obtained. |
