This paper proposes a simplified estimation method for Shock Response Spectrum (SRS) using a substructure synthesis method with a reduced impedance method. Since this method can compute SRS from each vibration characteristic of the space component and shock test apparatus, it has an advantage of estimating the SRS actually measured in shock test at the previous design stages. A novel method to improve the computation efficiency of the traditional impedance method is also proposed. This paper introduces a computation algorithm implemented in the traditional impedance method, and discusses the effectiveness of the proposed SRS estimation method.
