对钢厂的电动非正弦振动台在测试中出现颤动和不平稳现象的根本原因进行了分析,得出此钢厂振动台受振机构的固有频率低,装配时安装精度低和某些零部件出现磨损和损坏等是振动台出现颤动和不平稳现象的根本原因。提出提高受振机构的固有频率和减少产生共振的振源是解决颤动问题的根本方法。ANSYS分析得出加厚板簧能够达到提高受振机构固有频率和使其不容易出现颤动现象的目的。
The root cause of the vibration and instability of the electric non-sinusoidal vibrating table in the steel mill was analyzed, and the natural frequency of the vibrating table vibrating table of this steel mill was low, the mounting accuracy was low and some parts appeared Wear and damage are the root cause of vibration and instability of shaking table. Proposed to improve the natural frequency of the vibration mechanism and reduce the vibration source is the fundamental solution to the problem of vibration. ANSYS analysis shows that the thicker plate spring can achieve the purpose of improving the natural frequency of the vibration-absorbing mechanism and making it not prone to the phenomenon of vibration.
