Application of reliability-based design optimization to durability of military vehicles

摘要: In the Army mechanical fatigue subject to external and inertia transient loads in service life of systems often leads a structural failure due accumulated damage. Structural durability analysis that predicts components dynamic stresses strains is compute intensive multidisciplinary simulation process, since it requires integration several computer-aided engineering tools considerable data communication computation. Uncertainties geometric dimensions manufacturing tolerances cause indeterministic nature component. Due fact uncertainty propagation under loading not only numerically complicated but also extremely computationally expensive, challenging task develop durability-based design optimization process reliability ascertain whether optimal reliable. The objective this paper demonstration an integrated CAD-based effectively carry out for durability, yielding durable cost-effectively manufacturable product. This shows preliminary results reliability-based Stryker AArm.
