摘要：

摘要：为改进超压气球当前裁剪设计的缺陷，提出了一种索网蒙皮结构超压气球的设计方法.不同于通常采用与蒙皮固定的加强筋承担纵向应力的方法，该方法采用能与蒙皮相对滑动的绳索来承担大部分的纵向应力，同时兼具2D裁剪设计和3D裁剪设计的优点.通过改变绳索的预紧力实现了对球形初始构型的控制.采用等强度设计准则，根据蒙皮材料和绳索材料的极限强度计算得到了超压气球合理的初始构型，提高了材料的利用效率.讨论了各参数对超压气球极限压差的影响，其对于超压气球的结构设计与力学分析具有参考价值.

Abstract:

Abstract： In order to improve the current defect of super-pressure balloon gore design, a new approach to designing the superpressure balloon with a cablenet envelope structure was proposed. Different from the old approach, the load tapes sealed to the envelope was replaced by cables which could slid on the envelope to bear the longitudinal load. This approach combined the advantages of 2-D gore design with 3-D gore design. The controll of the initial configuration of the balloon was realized by changing the preload of the cables. According to the equal strength design criteria, the optimal initial configuration of the superpressure balloon was calculated with the ultimate strength of envelope and cable to improve the utilization efficiency of material. The influence of each parameter on the ultimate pressure of super-pressure balloon was discussed, providing reference for structure design and mechanical analysis of super-pressure balloon.

Key words: cable-net envelope structure, super-pressure balloon, preload, initial configuration, equal strength design criteria
