| Abstract: | In time domain and frequency One,the article analyses the dynamic perfor-mance of strong motion accelerograph in direct record way for QZY model of China and SMA-1 model U.S.A. and SMAC-B2 model of Japan.The technical index of dynamic perfor-mance for the system to follow and to reproduce seismic acceleration signal fast,steady andaccurately has been given in this paper.On the basis of above disicussion,we analyse the high frequency error of accelerographof direct recod way.At last the method of error correction of high frequency is discussed. |
