摘要
本文依据作者提出的由加速度记录实时仿真速度、位移时程和由速度记录实时仿真加速度时程及位移时程时域实时方法,对福建省和黑龙江省在同一台基上记录到的宽频带加速度记录与速度记录分别进行了仿真,并与仪器记录进行了比较分析。结果表明,可由宽频带加速度记录仿真得到真实的速度与位移时程;由宽频带速度记录也可得到加速度时程和位移时程,但对加速度时程高频成分会有一定的损失;应用此方法也可以仿真得到某一型号地震仪或者强震仪记录。
This paper uses real-time time domain methods to do real-time simulating based on acceleration records to get velocity and displacement time histories, and do real-time simulating based an velocity records to get acceleration and displacement time histories. Here, we do simulating both for Fujian Province's and Heilongjiang Province's wide band acceleration and velocity records, and these records was recorded by a same base station, then we compare them to instrument's records. The result shows that we can get actual velocity and displacement time histories by simulating wide band acceleration record. Result also shows that by simulating wide band velocity records we can get acceleration and displacement time histories, but high frequency part of acceleration time histories will have partial loss. By using this method we can also get records of a certain kind of seismograph or strong-motion instrument by simulation.
