摘要
研究了弹性基础上横向动力载荷作用下Euler梁的瞬态动力响应问题.采用模态叠加法推导出了动力载荷作用下弹性基础上梁的动挠度解析表达式,且分别给出了梁在突加和阶跃两种载荷作用下中点挠度的动力响应曲线.
The transient dynamic response to an Euler beam rested on the elastic foundation subjected to the transverse dynamic load is studied. In the article, the analytical solution＇s expression of the driving deformation of beam is derived by using modal superposition method, and the dynamic response characteristic curves of the central deflection of the beam versus the non - dimensional time under the sudden load and step load are plotted.
