【Abstract】 In view of the reasonableness of the original calculation method of the load on lifting ring in the hull block turning process,the parameterized model of the turning process was set up. The function of the load on the lifting ring was analyzed. The variation law of the load on the ring was studied. The results showed that the position relationship between the center of gravity,the rings and the break points determines the change trend of the load of the rings. Taking the hull blocks with different shape of sections as examples,the calculation model and method were verified to be practicable for design of turning process.更多还原
