Random Vibration Fatigue Analysis of Car Roof Luggage Carrier

Öz

In this paper, random vibration analysis was applied to predict the car roof luggage carrier's fatigue life. Ansys Workbench 19.2 program was used in this study for finite element analysis. The car roof luggage carrier geometry has meshed with 325,536 nodes and 105,682 elements. Random vibration analysis was applied by defining a 75kg load on the car roof luggage carrier applied according to the vibration and PSD data obtained according to the engine, wind, and road conditions of the vehicle, and it was estimated that no fatigue damage would occur for a minimum of 154564 hours using the Steinberg method.
