ABSTRACT: The results of kinematic motion analysis were used
for the structural analysis based on data that the load applied to each part.
The problem of the fatigue strength estimation of materials or components
containing natural defects, inclusions or in homogeneities is of great
importance for both a scientifically or industrial point of view. Fatigue behavior in components is often affected by the
presence of residual stresses introduced by processes such as actuator system.
Analysis can provide the estimation of the crack growth curves with sufficient
accuracy, even in case of complicated bell crank structures which are crucial
for preserving aileron integrity and which participate in transfer of load.
Probability of crack detection or any other damage detection is a result of
many factors. An endurance life prediction of bell crank is used finite element
analyses. Endurance test data for slim test specimens were compared with the
predicted fatigue life for verification.
