Research on the optimization of a bulk carrier based on the modified function method
英文摘要:With the improvement of green energy saving requirements, new requirements have been put forward for the quality and design cycle of ship optimization work. Aiming at the time-consuming and low efficiency characteristics of traditional hull form optimization methods in the hull deformation stage, an automatic deformation program was developed based on the modified function method. Using this program, the automatic deformation of the hull lines of the 210 000DWT bulk carrier was realized. Combining the experience of CFD, carry out line optimization of the bow and stern, and analyze the CFD results of each hull form in the optimization process, and finally obtain the optimized hull form with the best overall performance. In addition, the final optimized hull form was verified by a towing tank model test. The test results showed that the power received by the propeller of the optimized ship was about 3% lower than that of the initial ship. This method has successfully realized the rapid deformation of the hull lines. Compared with the traditional manual modification of the hull form, it saves a lot of time, can obtain a larger number of hull form schemes, and improves the optimization efficiency of the hull form while meeting the performance index requirements.
