| 摘 要： | 研究了有双轴对称截面开口薄壁压杆与弹性支承偏心连接时弯扭耦合振动，把作用在开口薄壁压杆的弹性支承去掉，代之以相应的约束反力和约束扭矩，推导出了开口薄壁压杆弯扭耦合振动时的位移函数，求得了其弯扭耦合固有振动频率的特征方程。

| Abstract: | The flexural-torsional vibration,when the biaxial symmetric open thin-walled press bar is eccentrically connected with the elastic bearing,is studied here.Provided that the elastic bearing at the thin-walled open press bar is replaced by the equivalent constrained force torque,the displacement function of flexural-torsional vibration at the bar is deduced,and consequently,the eigen equation of the inherent vibration frequency is worked out. |
