ABSTRACT

Road roughness excitation apply on rear axle housing of truck in time domain to make vari￾able force and reasonoffatigue failure on it. Many researchers on this field showed that it is trust

using random road roughness excitation as input data to solve and analyse problems. Dynamics

force apply on axle housing to estimate fatigue failure. On this research, we calculated input data

then using to analysis fatigue during time life of truck. This paper showed that the methodology and

standazation to estimate life lime of rear axle housing truck.

Keywords: Fatigue failure, driving axle housing, dyrmmic model, ISO 8608:1995.
