摘要
分析了三类瞬态激励的不同特点,从能量谱密度分布与输出激振能量方面,进行理论分析计算,并对有关信号处理问题进行了讨论。最后给出试验结果。为合理选择瞬态激励方式,提供理论依据。
In this paper, the author presented the characteristics of threekinds of transient excitation. The theoretical computation of energy spectral densityfunction and exciting energy was conducted. Some problems of signal processingwere also discussed. The experiment results are coincident with the theoretical analysis.
