抄録

<p>Improving quietness is an important issue in automotive design. Many studies have been reported on the use of a stiffness sensitivity to identify effective design changes. However, calculating a stiffness sensitivity using experimental measurements requires a large number of strain sensors, making it difficult to use in automobile design. Therefore, we propose a simplified method to evaluate strain energy focusing on elastic deformation and to calculate stiffness sensitivity more easily. The validity of the proposed method is confirmed using a simple flat-plate FEM model.</p>
