  • Patent number: 7302826
    Abstract: Provided are shock waveform synthesis methods for a shock response spectrum over a short time interval, which are used for a shock response spectrum test. For the purpose, the shock response spectrum test is performed by including the steps of: obtaining each time ?k (k=1, 2, . . . , M) at which a maximax value is detected in the response history due to a zero delay wavelet input, wherein a natural frequency of the SDOF system with a Q (quality factor) of 10 equals to the wavelet frequency of the zero delay wavelet input; and establishing each delay time ?k as ?k=?1??k (k=1, 2, . . . , M).
