Embodiment Construction
[0049] In order to make the technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:
[0050] Step 1: Create a 3D simulation image of a ship
[0051] Use general-purpose computer modeling software, including ANSYS, PATRAN, SESAM and other commercial engineering software, to establish the finite element model of the target ship, and use AWQA software for hydrodynamic analysis to generate ship model node coordinate information, unit connection information and ship quality. , additional mass, damping coefficient, wave incident force, wave diffraction force and other hydrodynamic parameters. The present invention will read the result file, and filter and record the above information through a matching algorithm. On the one hand, according to the type value information and node in...
