Responsible for supplying energy to electric equipment, secondary power supply of spacecraft is the foundation for the normal operation of electric equipment. Its key status decides the high requirement for performance stability and reliability. Due to the spacecraft product characteristics like small sample, long life and high reliability, it is hard to apply traditional life evaluation methods based...
The paper demonstrates an analysis example of a flange-sealing structure. Taking the O-ring width and bolt pre-tightening force as tolerance-parameters, obtaining the stress response surface according to the loop analysis results by ANSYS, then extracting the stress results of randomized parameters from the stress response surface, plotting the stress response distribution and calculating the reliability...

In this paper the different stiffening types (rectangular, V-shape, arc-shape) and their locations on the web how to influence the critical stresses of local buckling and distortional buckling and meanwhile the ultimate resistance capacity of the channel steel members is investigated. For the best stiffener i.e. V-shape stiffener, the influences of intersection angle between flange and lip on the...
