摘要
采用研究复杂隔振系统的子结构导纳法建立旋转类复杂结构的功率流传递模型 .重点研究了作为连接子结构的滚动轴承的模型建立及其对系统动态特性的影响 ,在系统建模后 ,研究了不同的能量传递路径及各传递路径之间的耦合 .以功率流为参量 ,对于引起箱体壁横向振动的能量做了定量分析 .
Rolling element bearing which connects shaft and casing plate is applied as the multidimensional compliant joint and the mobility/impedance power flow mathematical model is developed to analyze the dynamic behaviour of the system with rotational substructure. Transmitted powerflow are obtained by using the formulations. Then the comparison quantities are broken up into two paths to quantitatively examine how casing plate flexural motion is excited by shaft's bending motion.
