【摘要】 以振动噪声控制的经典模型(振源<轴>-路径<轴承>-接受体<箱板>)为基础,建立齿轮箱类结构的广义模型:轴-轴承-板,针对柔性质量轴、箱板以及轴承传递能量的多维性,推导轴、轴承和板的导纳矩阵和功率流传递的表达式,以功率流为评价手段,获取研究齿轮箱类结构的动力学特性.更多还原

【Abstract】 A general model is modeled as shaftbearingplate for gearboxlike structure.On the base of the classical model of vibration noise control, that is, vibratory source(shaft)path(bearing)receiver(plate of gear box), considering flexibility of shaft with mass, plate and multidimensional feature, we derive the formulation of mobility of shaft, bearing and plate and expression of power flow. The dynamic characteristics of the gearboxlike structure is studied by the way of valuing power flow.更多还原
