摘要
介绍了用微分变换法求解变截面梁的振动,并对变截面梁-板耦合结构的功率流进行了研究,分析了梁的不同结构参数对功率流传递的影响,为梁-板耦合结构的减振设计及新型梁式宽带吸振器的设计提供了重要参考。
The power flow characteristic of beam-plate coupling structure is studied. The differential transform is used to solve the vibration problem of the non-uniform beam. The power flow characteristic of beam-plate coupling structure is discussed. The effects of the parameter variation of non-uniform beam and the position difference on the power flow are discussed in detail by numerical simulation. The results provide the basis for reducing vibration of the non-uniform beam-plate assembly in engineering design.
