A new approach for non-Gaussian vibration analysis of hyperbolic
tangential package
Abstract
A new approach is proposed to analysis the non-Gaussian random vibration
of hyperbolic tangential package. Firstly, the non-Gaussian vibration
noise of specified mean, variance, skewness and kurtosis is developed by
Hermite polynomial, and verified by Gaussian mixture model (GMM) theory.
Secondly, next to analyzing an analytical and numerical response of the
two degrees of freedom (TDOF) linear package, the acceleration response
of the TDOF hyperbolic tangential package system (HTPS) under
non-Gaussian vibration excitation is obtained though the Hermite
polynomial and Runge-Kutta method, and the effects of the external
excitation and system parameters are investigated. Finally, on the basis
of the first-passage probability of the acceleration response, the
reliability analysis method is introduced. The analysis provides a
guidance to the vibration reliability analysis and packaging
optimization design.
