Reliability-based optimisation of automobile components

Techniques from the perturbation method, the reliability-based design theory and optimisation techniques are employed to present a practical and effective method for the reliability-based optimisation of automobile components. The theoretical formulae for reliability-based optimisation are obtained. The most probable point perturbation method (MPPPM) and reliability-based optimisation theory are employed to develop the reliability-based optimal design of automobile components. Two examples are used to illustrate the reliability-based optimisation formulation and demonstrate the method. The accuracy of the approach proposed is evaluated by comparing their results to that obtained from Monte Carlo simulations (MCS).
