Abstract
For the problem of fatigue failure on launcher trail cover in random vibration test , the ran-dom vibration fatigue life is estimated by finite element method .The stress transfer function is obtained by frequency response simulation .Combined with S-N curve of 5 A06 aluminium alloy and acceleration power spectral density loads , random vibration fatigue life of trail cover is analyzed by Dirlik method .The results meet the requirements of random vibration test .关键词
