摘要:
考虑两种不同频率的周期外部激励的作用,建立了含有准周期外部激励的叶片辊轧机非线性垂直振动动力学模型。采用多尺度法求解了系统主共振情况下的幅频特性方程,研究了系统在两种频率周期外部激励作用下的幅频响应变化规律,并且研究了高频激励参数对系统的动态特性影响。研究结果表明:随着高频激励系数的增加,系统的固有频率增大,系统主频与高频振动幅值加剧;高频激励频率在一定范围内增大,则高频振动幅值相应减小。
Nonlinear vertical vibration dynamic model of blade rolling mill was established based on the action of periodic external excitation under two different frequencies. The change law of amplitude-frequency response under the periodic external excitation of two different frequencies and the influence of high frequency excitation parameters on dynamic characteristics of system were studied through the method of multiple scales to solve amplitude-frequency characteristic equation of system with resonance. It is concluded that natural frequency increases with the rise of high frequency excitation coefficient, and the vibration amplitudes of the main system frequency and high frequency increases. As the frequency of high-frequency excitation increases within a certain range, the high frequency amplitude decreases correspondingly.
