Recently reduction of allophone of motors for automobiles has received a great deal of attention. For this background, the final goal of our research is to develop a simulator for transfer characteristics of allophone of motors in automobiles. In this paper at the preparation phase for the development of a simulator, we investigated the applicability of the transfer function synthesis method (TFSM) experimentally. Additionally, we examined some problems to be solved for practical use of the TFSM by using the finite element method (FEM). As a result, it was found that the derivation of the transfer functions H22 and H33 at the connecting point was difficult and that the modeling accuracy of H22 and H33 had a large influence on the modeling accuracy of the total transfer function H41_sim. Moreover, the method to improve the modeling accuracy was proposed on the basis of the results by FEM analysis. It was confirmed that we could apply the TFSM to the simple test body with the contact area by using the proposed method and the adjustment for damping coefficient of the transfer function obtained by the curve fitting technique (CFT).
