Dynamic Analysis of an Engine Chassis Mount Bracket Using the Finite Element Method

This paper presents an application of the finite element technique to the solution of the dynamic behavior of an engine chassis mount bracket. The method is used for prediction and evaluation of the natural frequencies and mode shapes of the engine chassis mount brackets. The influence of the C-section edges, ribs, bolt holes and boundary constraints on the modes of an engine bracket are analyzed according to the requirements for an engine mount. Some suggestions for improving the dynamic behavior of the engine bracket are presented.
