| Abstract: | According to ship hydrostatic principle,a hydraulic force calculation program is established to carry out the calculation for launching of a 19 200 DWT bulk carrier with gasbags.Calculation for displacement of gasbags and total longitudinal moment is carried out with nonlinear finite element program,so that the validity of self-program is approved.Structure stress analysis for the ship has been put up particularly with finite element program,the result shows that the launching of the 19 200 DWT bulk carrier... |
