摘要： A method and system for determining locations in a design of an assembly likely to result in buzz, rattle squeak (“BSR”), and/or other noise conditions. The invention uses a finite element model to represent a design. BSR effects are predicted based upon analysis performed on multiple design models. Users may engage in real-time “what if” analyses to determine the effects of various design and component changes on noise source characteristics. Additional intelligence may be applied to limit the number of model points subject to evaluation. Displacements, contact velocities, and force responses at selectively identified subsets of interesting points can evaluate noise characteristics. An “as designed” model may evaluate noise source characteristics at the beginning of the life of an assembly. Degraded models can determine the effects of aging and use. A restored model may evaluate the influence of optimal fastener design on BSR characteristics for assembly resulting from fastener degradation.

摘要： A vehicle frame structure includes an outer pillar panel, an inner pillar panel and a bulkhead. The outer pillar panel includes an outer upper end, an outer lower end and an outer bulkhead attachment section located between the outer lower end and the outer upper end and at or above a mid-point of the outer pillar panel. The inner pillar panel includes an inner upper end, an inner lower end and an inner bulkhead attachment section located between the inner lower end and inner upper end and at or above a mid-point of the inner pillar panel. The bulkhead is fixedly coupled to the outer and inner bulkhead attachment sections.
