| Abstract: | The calculation results for dynamic optimization of hull grillage are analyzed again. Some different conclutions are obtained in goal function and variabls selection. According to the characteristics of natural frequencies of hull grillages, some effective mesureas are suggestedfor avoiding the forbidden zones of frequencies. |
