【Abstract】 Based on the linear model of seismic simulating apparatus, one order sensitivity model is applied to analyze the sensitivity functions of 3-state feedback parameters of a seismic simulating apparatus and its effect on the dynamic characteristics of the apparatus. The degree of the effect of variation of 3-state feedback parameters on the apparatus characteristics is studied with digital simulation.更多还原
