船舶气囊下水技术是我国具有自主知识产权的一项创新技术。文章介绍了气囊下水过程计算的数学模型和计算机程序设计思路，推导气囊刚度计算公式并论述了程序设计的关键。编制的程序已获得软件著作权，经多艘大型船舶试用，其结果符合预期要求，可供方案比较、安全评估和遴选环境参数使用。%Ship launching with airbag is an innovative technology with China’s independent intellectual property rights. This paper introduces the mathematical model and the programming concept for the calculation of the air-bag launching, deduces the formula of rigidity of the airbag, and describes the key points of the program design. The copyright of the compiled program has already been secured. The program is applied on many large vessels and is validated accord with the expected results, which can provide scheme comparison, safety assessment and check and the usage of environment parameters.
