感度解析を用いた振動システムの同定 : 第4報, 減衰特性を有する弾性体で支持された剛体系への適用

抄録

The authors propose a method of direct identification of design parameters (mass, location of the center of gravity, the moment of inertia, spring constant, damping constant and the location of the support of elastic mounts) of a damped vibration system of rigid and elastic mounts. In this method, modal parameters are repeatedly modified by changing the design parameters based on the sensitivity analysis of the complex eigen value in order to correspond to the objective values (damped natural frequency, modal damping ratio, mode shape coefficients). A calculation model and a rigid body model are examined to verify the usefulness of the method.
