摘要
本文对大型自卸船(包括经济型自卸船)的振动性能预报进行了研究分析 ,提出了大型自卸船振动性能预报的计算方法 ,编制了大型自卸船船体振动性能预报程序系统CSSVIB。并通过建立各种计算模型 ,对七万吨自卸船进行了船体总振动、舱室局部结构振动、机舱底部板架振动和上层建筑振动的计算分析。计算结果表明 ,七万吨自卸船的振动性能良好 。
The vibration characteristics prediction of a large self-unloading ship(including economical type)are researched in this paper.The method for vibration prediction of large self-unloading ships is described .The program system CSSVIB of vibration characteristics prediction of large self-unloading ship is developed .By the different calculation models,the hull general vibration,the cabin local vibration,the grillage vibration in the engine room as well as the superstructure vibration of the 70000DWT self-unloading ship are calculated.The results show that the vibration characteristics of the 70000DWT self-unloading ship are good enough and satisfy vibration criteria.
