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.
