在使用电动式激振器来推动闭式静压导轨水平滑台做土坝、堆石坝……等的模型抗震试验,或用电动式激振器来推动动三轴作土的单元体动力特性试验时。有限次的振动将使模型或试件受到破坏,因此在做正弦波形定频稳态振动时,对振动的加速度,次数和振动起始、停振的位置,以及振动台与记录仪器的联动等 In the use of electric exciter to promote closed hydrostatic guideway horizontal slide to do Earth dam, rockfill dam ... ... and so on the model earthquake test, or use electric exciter to promote the movement of the triaxial shaft for the soil body Characteristic test. A finite number of vibrations will damage the model or the specimen. Therefore, the acceleration, the number of vibrations, the position of the vibration stop and the linkage between the vibrating table and the recording instrument during the steady-state sinusoidal steady-state vibration
