研究摇床选别原理离不开对床头运动规律的分析。至今,摇床头运动分析方法有二,一是图算法一是实测法。实测法较图算法迅速,配有速度和加速度传感器的测震仪可直接获得位移、速度和加速度曲线。既是实测,也就是只能对已有床头进行实测分析。图算 Research on the principle of shaking table sorting is inseparable from the analysis of bed movement rule. So far, shaker head movement analysis methods are two, one is the graph algorithm one is the actual measurement method. The actual measurement method is faster than the graph algorithm, and the seismometers equipped with speed and acceleration sensors can directly obtain the displacement, velocity and acceleration curves. Is both measured, that is, only on the bed has been measured. Figure count
