利用壳体振动理论建立一般旋转壳体的振动方程,并通过传递矩阵法进行数值求解。在动、静坐标系下分析了壳体长径比、厚径比及其边界条件对行波振动特性的影响,在高速旋转实验台上对旋转壳体采用冲击激励的方法进行动模态参数识别。理论和实验结果表明,高速旋转薄壁壳由于科氏力的影响,同一模态振型对应两个不同频率的前、后行波且不会出现驻波现象。壳体几何尺寸的变化对模态振型有较大的影响,而边界约束的不同对低阶模态参数有影响。 The vibration equation of a general rotating shell is established by using the shell vibration theory and solved numerically by transfer matrix method. Under dynamic and static coordinate system, the effects of shell aspect ratio, aspect ratio and boundary conditions on the vibration characteristics of traveling wave were analyzed. The dynamic modal parameters Recognize. Theoretical and experimental results show that due to Coriolis force, the same mode shape corresponds to the front and back traveling waves of two different frequencies and the standing wave will not appear in the high-speed rotating thin-walled shell. The change of the shell geometry has a great influence on the mode shape, while the difference of the boundary constraints has an impact on the low-order modal parameters.
