摘要 直联式隧道通风机是隧道中的重要设备,其机械传动过程产生的瞬态振动会影响通风机正常运行。为此,该文提出针对直联式隧道通风机机械传动过程瞬态振动的控制方法。首先,通过拉格朗日方程推导出直联式隧道通风机机械传动系统的动力学模型;然后,通过线性FxLMS算法完成对瞬态振动的初步控制;最后,利用跟踪滤波器和非线性变换函数,通过更新准则优化线性FxLMS算法,实现对瞬态振动的精准控制。实验结果表明,应用该方法后,风筒顶层位移和振动加速度幅值明显减小,减振率有所提高。 The direct connected tunnel fan is an important equipment in the tunnel,and the transient vibration generated in the mechanical transmission process will affect the normal operation of the fan.Therefore,a control method for the transient vibration of the mechanical transmission process of the direct coupled tunnel fan is proposed.Firstly,the dynamic model of the mechanical transmission system of the direct connected tunnel fan is derived through Langrange equation.Then,the linear FxLMS algorithm is used to control the transient vibration.Finally,the tracking filter and nonlinear transformation function are used to optimize the linear FxLMS algorithm through updating criteria to achieve accurate control of transient vibration.The experimental results show that the displacement and vibration acceleration amplitude of the top layer of the air duct are significantly reduced,and the vibration reduction rate is improved.
