摘　　要：根据船舶静力学原理,编制船舶气囊下水静水力计算程序,进行19 200 DWT散货船的气囊下水计算;采用非线性有限元程序,进行该船气囊变形和总纵弯矩计算,验证了自编程序的正确性;采用有限元程序,进行下水过程的船体应力分析,并获得船底板的最大应力。最终证明了该船气囊下水的安全性。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 selfprogram 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 cartier with gasbags is safe.
