Abstract

The theoretical principle of mode analysis was introduced. The finite element models of the empty and loaded car body of special gondola car were built, and then the mode analysis and verification of the two models were studied. The results show that the two finite element models of empty and loaded car body of special gondola car are accurate and reliable. Furthermore, a new way is provided to analyze the mode of car body embarked by bulk cargoes, and a solid foundation is laid for further dynamic researches.
