摘　　要：采用Wigner分布算法设计了变速箱故障诊断系统,特别适用于识别因故障而产生的调幅和调频边频带。实验表明效果较好,对于提高故障诊断水平,使现代故障诊断理论在工程实际中更好地发挥作用有着重要意义。In this paper,a system for diagnosis the malfunction of gear-boxes based on Wigner distribution is designed. It's especially used in recognizing the side frequencies caused by amplitude modulation and frequency modulation.Experiment results indicate that it performs well and is significant in engineering practice.
