Abstract


In order to make students better understand the dynamic characteristics of the measurement system of the engineering measurement course, the simulation software of the first-order system and second-order system has been developed by using Delphi computer language. The amplitude change and phase shift of the output signal can be obtained under the condition that the system characteristic parameters are preset. It is helpful to strengthen the understanding of the time constant of the first-order system and the resonance frequency n and damping ratio of the second-order system. The simulation software shows the intuitionistic and visual merits on the demonstration of the dynamic response of the first-order system and second order system under the certain input signal.
