Abstract
According to analyzing the force situation of the ship-based helicopter moored on the ship, a equation set of verti-cal deformation of landing gear based on virtual work principle was derived. Then, the mooring tension was calculated by deformation of landing gear. Newton iterative method was used to solve the equation set. It was found that the mooring ten-sion were mainly distributed to main landing gear’s cable when roll amplitude were bigger than pitch amplitude and wind load couldn’t be ignored. Finally, the influence of tyre’s rigidity was analyzed. The results showed that the biggest tension decreased 7.43%when the tyre’s rigidity increased from 300 N/mm to 800 N/mm tyre’s. That was to say it could improved the safety of the moored helicopter.关键词
