Abstract

The influences of packages’jumping and cushion material nonlinearity on acceleration responses of packages were investigated with tests. Under random vibrations,acceleration response features of packages were analyzed in frequency domain and time domain. Results indicated that under Gauss excitation,package jumping was the main reason to cause packages’acceleration responses having non-Gaussian features. Under unconstrained conditions,packages have obvious jumps,their acceleration responses’probability density distribution is a non-Gaussian one; under elastic and fixed constrained conditions,jumping of packages is restricted,when the vibration intensity is larger,acceleration responses’distribution of packages deviates from Gaussian distribution to some extent,when the vibration intensity is smaller,acceleration responses’distribution of packages is a Gaussian one.
