摘要
En 中文
This paper presents a method that can be used to obtain the motion transfer functions of a ship when the detailed hull geometry is not available. In the method, any parameterised transfer function can be optimised from a data-driven approach that compares a measured response spectrum and the corresponding theoretical spectrum based on the combination of transfer function and wave spectrum. The established method facilitates association of 95% confidence bands which are useful to indicate a level of trust. The proposed method is evaluated on a conceptual level using both simulated and in-service measurements, and promising results are obtained.
