| Abstract: | A digital simulation method of multi-freedom vibration system was presented. The vibration system is described as the state-space equation. Then, the continuous equation is solved by impulse response method. Last, a discrete recursive formula is driven from the solution. Given a digital input to the recursive formula, a digital response can be measured. The simulation experiments of vibration system show the correctness of the algorithm. |
