摘　　要：浮空器副气囊体积动态变化攸关浮空器的安全,对其准确建模及实时客观评估一直是浮空器设计的难点。然而通过观察窗查看体积刻度线来粗略估算副气囊体积及采用单激光测距仪进行测量都存在评估不准的问题。针对上述难点和问题,对浮空器副气囊的体积确定进行建模分析研究,提出一种采用双高精度相位激光测距仪测量副气囊丰满度并使用最小二乘法对副气囊体积进行评估的方法。该方法根据实时准确的丰满度数据,建立了副气囊体积与丰满度之间的关系式,实现对副气囊体积实时动态评估。试验与数据分析表明该方法能够较准确地对副气囊体积进行动态评估,验证了理论模型和通过丰满度测量评估体积的合理性,在浮空器工程设计中提供了一种可供参考的设计思路,具有一定的工程指导作用。The dynamic changes in the volume of aerostat auxiliary airbags are crucial for aerostat safety,posing challenges in accurate modeling and real-time objective assessment.Estimating the airbag volume by observing volume scale lines through observation windows or using a single laser rangefinder for measurement both suffer from inaccuracies.Addressing these challenges and issues,this study models and analyzes the volume determination of aerostat auxiliary airbags.It proposes a method utilizing dual high-precision phase laser rangefinders to measure the airbag fullness and employs the least squares method to assess the airbag volume.Based on real-time accurate fullness data,the method establishes a relationship between airbag volume dynamically,validating the rationality of theoretical model and volume assessment through fullness measurements.This method provides a reference design approach in aerostat engineering,offering practical guidance in the design process.
