Discussing the Effect of Different Modeling Methods on Bus Frame Modal Analysis Based on the Experiment

摘要

Using ANSYS to calculate modal of truss structure, which is similar to the bus frame, proposing the effect of different modeling methods on modal results and initial selecting the appropriate modeling method to this new type complex bus frame. The above-mentioned methods are used to create actual bus frame models and obtain the corresponding modal results. Then testing the accuracy of the results by modal experiment, to establish an accurate modeling method at last, this is laying the foundation for other analysis, and also providing reference for the similar frame structure.
