金属管棒材飞剪机构曲轴的优化设计
|
摘要
飞剪机主要用于剪切轧钢生产过程中轧材的头、尾或将其切成规定的尺寸。本文对飞剪机曲轴进行模态分析,建立曲轴有限元模型,并对曲轴的前四阶模态特性进行分析,从而得知当曲轴第一阶固有频率和工作频率较为接近时,容易出现共振现象,根据分析结果对四个方案的曲轴结构进行优化,可以避免共振现象的发生。
The flying shears cut the head and tail of the rolled material during the rolling production process or cut it into a specified size. The modal analysis of the crankshaft of the flying shear is carried out,and the finite element model of the crankshaft is established. The first four modes of the crankshaft are analyzed. The first natural frequency and the working frequency of the crankshaft are close,and the resonance phenomenon is easy to occur. The crankshaft structure is optimized to ultimately avoid resonance.
