摘要
为了确定振动轴的振动特性,避免筛煤机中振动轴被共振破坏造成对设备的危害,采用ANSYS软件对振动轴建模并进行模态计算。有限元分析中将轴承简单处理为刚性约束的方式,分析得出轴的前10阶固有频率和振型,为振动轴的工作频率选择避开共振提供了参考,同时为振动轴和筛煤机的正常运转提供设计依据。
In order to determine vibration characteristics of the vibrating shaft,to avoid resonance damage of the coal screen’s vibration shaft caused the harm to the equipment,modeling vibration shaft and calculating model by ANSYS software.The shaft is treated as simple processing of rigid constraints in finite element analysis,and top 10 order natural frequency and vibration type are obtained,which will provide the reference to avoid the resonance of the operating frequency of vibrating shaft and design basis for the normal operation of the coal screen its vibration shaft.
