Analysis on the Formulas'Regression of Motion and Acceleration in Strength Assessment of the Ore Carriers
The formulas of motion and acceleration in the location of ship's gravity center used for the strength assessment of very large ore carrier(VLOC)was studied.By comparing the numerical results of hydrodynamic calculation of four VLOCs with those of the calculation formulas stipulated in the Common Structural Code for Bulk Carrier and Oil Tankers(HCSR),it was shown that most of the formulas stipulated by HCSR are not suitable for strength assessment of VLOC.By modifying the inapplica-ble formulas,the new formulas of motion and acceleration at the center of gravity,which is suitable for strength assessment of VLOC was obtained.
