Improvement in the vibroacoustic diagnostics of rotors is considered. Sensitive and reliable signs are identified by the analysis of the two-dimensional probability-distribution densities of vibrational amplitudes. That approach permits assessment of the nonlinearity of the dynamic model for a machine regarded as a vibrational system. Diagnostics of the plant compressor conlition illustrates, among other things, the potential for indirect ongoing assessment of repairs.

带有操作缺陷的机器的异常动力学

考虑改进转子的振动声学诊断。通过分析振动振幅的二维概率分布密度，可以识别出敏感可靠的信号。该方法允许评估被视为振动系统的机器的动力学模型的非线性。工厂压缩机状况的诊断除其他外，表明了间接进行正在进行的维修评估的潜力。
