摘要
针对某新建的1420冷连轧机组,建立了轧机主传动系统动力学模型。通过计算得到系统的固有频率和反共振频率、振型和Bode图,并对系统的设计方案进行分析。结果表明,该冷连轧机主传动系统设计基本合理,部分设计参数还有优化的余地。
Focused on the newly-built 1420mm tandem cold mill group of some iron steel corporation,the dynamic models of the main driving system are established based on the basis of design drawing.The natural frequencies and anti-resonance frequencies,vibration modes and Bode diagrams of the system are gained by calculating.Subsequently,the analysis and judgement of the main driving system are carried out.The results show that the design of the main driving system is reasonable on the whole,but some design parameters need to be optimized.
