Random Vibration Analysis of Rivets on Payload Structure

Abstract:

A payload structure is joined by rivets, which are potential weakness in random vibrations and thus require safety examination. Based on the general finite element software ANSYS^®, a 3D whole-local finite element model of payload structure was established. The strength evaluation method is determined for rivets through a determinate transient dynamics analysis and related experiment under half sine impulse load. A Power Spectral Density (PSD) analysis is carried out and the rivets under random vibration environment were analyzed. The results of the random vibration analysis show that the design scheme of rivets is feasible.
