摘　　要：随着船舶建造的载重吨位越来越大,对现有的船台的承载能力是一个严峻的考验。文章通过将船体视作弹性梁,解决了船舶下水过程中,船舶尾浮时,首支架对滑道的压力过载的问题。从理论上证实了此下水方案的可行性,为船厂安全生产和节约成本起到了较大的作用,同时也为船舶下水受力分析提出了新的思路。As tonnage of ships increases,it is really a big challenge for slipway during ship launching.In the article,the hull is looked as an elastic girder and it is solved the over loading force of front bracket held on slipway when stern floating during launching.The article proves the feasibility of the launching solution.It benefits to the safe production and cost-saving for shipyards.Meanwhile it also brings a new concept for the force analysis during ship launching.
