摘要:
针对空间压力容器常规设计方法难以满足航天技术快速发展对轻质量、低成本、高可靠的需求，基于可靠性理论中应力-强度干涉模型，建立空间压力容器可靠性设计数学模型。结合某型号钛合金球形气瓶随机变量统计数据，开展了气瓶可靠性定量设计。计算结果表明，可靠性定量设计方法能够给出产品可靠度定量指标，并在一定程度上降低空间压力容器结构重量。
Abstract:
With the rapid development of aerospace technology, the conventional design method of the space pressure vessel can hardly meet the requirements of light weight, low cost and high reliability. The mathematic model for reliability design of the space pressure vessel is established based on the stress-strength interference model. The quantitative design for gas cylinder reliability is conducted in combination with the random variable statistical data of globular gas bottle made up of titanium alloy. The computation result indicates that the reliability design method can provide quantitative indexes for degree of reliability, and to some degree, can also reduce the weight of the space pressure vessel.
