This paper presents a study on a rattle noise in BSR by comparison between experimental results and numerical analysis results as to a vibrational model by FEM. Simulating a rattle noise, the vibrational model is constructed with a contact state by putting two pieces of strip-formed sheets made of the plastic on top of one another. As an input waveform, random vibration and sweep vibration are used, displacement excitation method is applied on a node which is pinned support. As a result, the influence of contact could be confirmed from the time history response analysis result by FEM with contact and without contact. Also, the effectiveness of the vibrational model with the influence of rattle noise is examined through calculations employing a FEM model with contact and without contact in the power spectral results of the analytical and the experimental results, it is shown that the analytical and the experimental results are qualitatively similar.
