Time domain non linear strip theory for ship motions
Fan, Y.T. and Wilson, P.A. (2004) Time domain non linear strip theory for ship motions. Royal Institution of Naval Architects Transactions A: International Journal of Maritime Engineering, 146, (3), 33-47. (doi:10.3940/rina.ijme.2004.a3.3404).
A new implementation of strip theory is proposed based on the strip theory by Salvesen, et al.  and early work by
Westlake and Wilson . Compared with traditional strip theory, the main difference is that the calculation is carried
out in the time domain. This makes it possible to cope with relatively large-amplitude motions and non-constant forward
At each time step, the exact underwater sections are extracted; the velocity potential is required to satisfythis instantaneous body boundary condition, therefore the added mass, damping coefficients and exciting forces are timevariant, which produce a non-linearity. The diffraction force is added to work ofWestlake and Wilson, and the results show the effect of diffraction force is significant.
