WebMay 17, 2024 · The impulse response function method (IRFM) is one of the methods to analyze wave-induced ship’s motions in irregular waves in the time domain. The Fourier transform relates the frequency-domain and the time-domain closely. WebIn signal processing and control theory, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an …

Radiation forces are kept as linear and presented in terms of impulse response functions using convolution integrals. In large amplitude waves, nonlinear motion responses are identified and presented in terms of transfer functions. The numerical results are well agreed with the experimental kowhai tree pruning

WebApr 15, 2024 · The impulse-response-function (IRF) method ( Cummins, 1962) is another popular method for simulating the ship motion response in coupling sloshing problems. By converting the frequency domain solutions into time domain data, the external wave action can be computed much faster than that of direct time-domain methods. WebCummins, W.E.
