摘要:
本文从复模态理论出发,探讨了在机床模态分析中,应用脉冲激振法激励机床时的一些问题。监用此法对 C336K-1回轮式六角车床进行激励和模态分析。通过付里叶分析系统的模态动态显示(可见录象),形象地演示了机床13阶整机的振动模态和主轴箱、六角头、床身和拖板等4个主要零件的分离振动模态。并清楚地反映了机床在结构上存在的问题。
Abstract:
Based on the complex modal theory,some problems arising in machine tool modal analysis by impulse excitation are examined.A C336K—1 turret lathe is used in this case.Through the modal dynamic display from a Fourier ana- lysis system (referring to video tape recording),13 order vibration modals of the whole machine tool and 13 order separate vibration modals of 4 main parts (headstock,turret,bed and carriage) are vividly shown.The problems of the machine tool structure can be clearly revealed.
