Fatigue failure is the typical failure mode of mechanical components subjected to random load-time history.
It is important to ensure that the mechanical components have an expected life with a high reliability.
However, it is difficult to reduce the influence of factors that affect the fatigue reliability and thus a reliability sensitivity analysis is necessary.
An approach of fatigue reliability sensitivity analysis of complex mechanical components under random excitation is presented.
Firstly, load spectra are derived using a theoretical method.
A design of experiment (DOE) is performed to study the stresses of dangerous points according to the change of design parameters of the mechanical component.
By utilizing a Back-Propagation (BP) algorithm, the explicit function relation between stresses and design parameters is formulated and thus solves the problem of implicit limit state function.
Based on the damage accumulation (DA) approach, the probability perturbation method, the fourth-moment method, the Edgeworth expansion is adopted to calculate the fatigue reliability and reliability-based sensitivity.
The fatigue reliability sensitivity analysis of a train wheel is performed as an example.
The results of reliability are compared with that obtained using Monte Carlo simulation.
The reliability sensitivity of design parameters in the train wheel is analyzed.
