abstract = "This paper presents the results of a study conducted to predict and improve the response of an engine mount using a hybrid model that combines both experimental data and finite element (FE) analysis. The engine mount is the main point of transmission of engine vibration forces to the
vehicle body. Therefore, improving the dynamic response of the engine mount improve the overall NVH performance of the vehicle. The hybrid modeling method adopts the substructure synthesis method based on the frequency response function based substructuring (FBS) theory, in this method, a
complex dynamic structure is divided into multiple substructures, and the frequency response function (FRF) of the entire system is predicted using the FRFs of individual substructures. This method allows engineers to predict the changes in the experimental FRF of an existing physical system
by applying FE analysis only to the substructures that have undergone a design modification. The change in the overall dynamic performance of the system can be predicted by modifying the CAD model of the substructure without preparing a physical model.",
