船舶慢速航行上浪现象及载荷模型分析

Model analysis of green water phenomena and loading for ship sailing with slow speed

运用概率理论和非线性动力学方法,建立船舶在慢速航行时上浪发生的临界条件和上浪载荷的计算模型,并在船舶操纵模拟系统环境中予以实现;对船速、波高、干舷、动升高等因素对上浪的影响进行比较分析.结果表明,建立的上浪载荷计算模型具有一定的科学性与合理性.

The critical condition and wave load calculation models were established and realized in large-scale ship maneuvering simulator environment by using probability theory and nonlinear dynamics method for ship sailing with slow speed.The effects of speed,wave height,freeboard,moving higher,etc on green water were compared.Results show the scientificalness and rationality of the proposed models.
