To get the reliability index of a bus body, material yield strengths, girder cross-section areas, panel thicknesses and external loads are taken as stochastic variables by fundamental theories of structural system reliability. Considering the dynamic load coefficient in the loading conditions of bending and torsion, the method which analyses the reliability of strength and stiffness of the bus body...
To diagnose effectively the aerocraft key structure components fatigue damages, discover in good time hidden trouble, avoid fearful accident occurring, the advanced acoustic emission (AE) technique is used to monitor the aerocraft stabilizer health state and get the AE information. Chaos theory is used to extract the correlation dimension of the AE information and construct the character vector. And...
