摘　　要：为了实现阶梯杆结构的减振控制,通过行波理论研究变截面阶梯杆中的振动,将振动视为结构中的行波,基于行波理论生成反向行波,通过正向波与反向波的相互抵消实现减振,并利用应力变化曲线量化振动抑制效果,经过数值分析阶梯杆的振动得到有效的控制。In order to realize the vibration damping control of the stepped rod structure,the vibration in the variable cross-section stair bar is studied by the traveling wave theory,the vibration is regarded as the traveling wave in the structure,the traveling wave in the opposite direction is produced by the traveling wave theory,the two traveling waves cancel each other,and the vibration effect is studied by the stress change curve,and the vibration of the stepped rod is effectively controlled by numerical analysis.
