摘　　要：研究了在轴向动力荷载作用下压弯构件的动力特征,根据压弯构件的动力平衡方程,导出了不同横向荷载形式下的振幅计算公式,分析了横向荷载对杆件动力性能的影响,根据理论研究成果提出了在实际工程中减小杆件振幅的一些措施.In this paper, dynamic characteristics of bending bar under axial dynamic loads were investigated. Formulas for amplitude of bending bar in different kinds of lateral loads were derived, and the influence of different loads on the dynamic property of the bar were studied. Some suggestions were given for reducing the amplitude of the bar in practical engineering.
