| 摘 要： | 应用能量的方法，研究了简支梁的几何参数对动荷载系数的影响，作出了动荷载系数随几何参数变化的曲线。通过实例得到梁在受到横向冲击时，考虑与不考虑梁自身质量情况下，动载荷系数误差较大。结果表明：动荷载系数随梁的高度增大而增大，随梁的长度、质量增大而减小。

| Abstract: | The researches are done by means of energy into the influence of geome tric parameters on the simply supported beam of the dynamic load coefficient;the curve of the dynamic load coefficient varying with the geometric parameter is drawn up.Through the real examples reflected that when beam under cross impact, whether it's mass or not,the error bigger.The conclusions are that the more the beam height,the more the dynamic load coefficient;the more the beam length and the mass,the less the dynamic load coefficient. |
