旋转梁在横向铰支纵向自由约束下的耦合振动

The coupling vibration on constraints of hinges at transverse and freeness at axial orientation of a rotational beam

研究绕一端旋转的弹性梁产生的拉压与弯曲的复合振动,采用分离变量法,求出旋转梁在横向受两端固定铰链约束、纵向两端自由弯曲和拉压耦合振动的微分方程通解.

In this paper, the coupling vibration at bend and extension of a rotational elastic beam was studied, and the general solution to the vibration differential equations of the rotational beam on constraints of hinges at transverse and freeness at axial orientation was obtained by the method of separate variables.
