本文综合几种矿山机械典型结构,建立两种简化力学模型,研究它们的振动规律,且与实测数据对照分析,以确定影响振动频率及振幅的主要因素。此外还通过实例简要地介绍了用频谱分析法揭示系统特性寻求主振源的理论依据及分析方法。最后研究了振源控制与隔振在矿山机械研究中的具体应用。 In this paper, the typical structures of several mining machinery are summarized, and two simplified mechanical models are established to study their vibrational rules, and compared with the measured data to determine the main factors affecting the vibration frequency and amplitude. In addition, it also gives a brief introduction of the theoretical basis and analysis method of using spectral analysis to reveal the system characteristics to seek the main source of vibration. Finally, the concrete application of vibration source control and vibration isolation in mine machinery research is studied.
