中文摘要

This paper aims at the development and validation of the Finite
Element Model (FEM) of a welded structure for a transit bus. The integrated
structure is generally fabricated by the assembly of several substructures,
including the front-end, body-side, rear-end, roof, floor and chassis assemblies,
through the welding and suspension linkages. A well-developed and validated
FEM for such a complex and large structure is critical to the further structural
analyses. Experimental Modal Analysis (EMA) is conducted on each
substructure and then the integrated structure. The natural frequencies and the
associated mode shapes obtained from EMA are used to validate those of from
the FEA. Good correlation between EMA and FEA guarantees that the
distributed stiffness and mass of the FEM are equivalent to the real vehicle
structure. This validated model is then qualified for the further analyses such as
structural stiffness, strength and impact crashes.
