• Natural frequencies, natural modes and transfer functions of a combination of crankshaft and flywheel are investigated by a reduced impedance method the author proposed. The crankshaft is divided into a straight shaft part and an arm part. The straight shaft part is expressed first by the transfer matrix of Timoshenko beam, which is transformed into an impedance matrix. The arm part and the flywheel are expressed by the finite element method, and the impedance matrix of the arm part and the flywheel is reduced to the degrees of freedom of only the central node of their boundary parts. An equation of motion of the total body is made of these reduced impedance matrices, and this equation is solved to get natural frequencies, natural modes and transfer functions. The calculated results agree well with the experimental ones.
