Wang, Yi., Wu, W. and Guedes Soares, C. (2020), Experimental and numerical study of the hydroelastic response of a River-Sea-Going container ship, Journal of Marine Science and Engineering, Vol. 8(12), 978 (20 pages)
The hydroelastic behaviour of a River-Sea-Going ship hull is analysed experimentally and numerically. A segmented ship model connected by a steel backbone is tested in regular waves and its high frequency vibrations such as springing and whipping responses have been identified. The hydroelastic response of the ship is numerically calculated using a hydroelastic time domain method based on strip theory, which is extended to include an improved model of the slamming load. The slamming forces in the bow section are determined by the Modified Longvinovich model (MLM) instead of the Von Karman model. The vertical motions and wave induced loads are calculated and compared with experimental results. The response amplitude operators of the vertical loads and the high order harmonics are analysed under different speeds showing good agreement with experiments. Slamming loads on the bow section of a River-to-Sea ship are predicted utilizing MLM model and compared with Arbitrary Lagrangian Eulerian algorithm by LS-DYNA and with measured results.
