Circuit Equivalence and Solution to Man-Machine Interface Problem of Farming Machine

In this paper, considering of matter gravitation, an improved equivalent circuit of single-freedom-dimension vibrating system has been put forward, and applied to man-machine interface problem of farming machine. This paper also gives out a way to solve the man-machine interface problem for the steady feature of sucessive vibration and the transient response to impulsion in the point of view of pure circuit theory.
