| 摘 要： | 选择合适的挠曲线方程和转角方程,采用能量法计算了变截面梁在考虑剪切变形影响时的挠度.该方法原理清晰,计算简便,精度较高,而且适于编程电算,对工程设计人员具有一定的参考价值.算例计算结果还表明,对于两端固定的变截面梁,当其截面尺寸较大和计算长度较小时,剪切变形对梁挠度的影响不可忽略不计.

| Abstract: | A method is presented in this paper for calculating the d eflection of tapered beam with shear effects by choosing an appropriate deflecti on equation and an appropriate slope equation.This method is deduced from the energy method.It's easy,precise for calculation and fit for programming.This method is efficient to use for designers.And it's found from the example that the shear effects can't be ignored to the deflection of tapered beam of which t he section dimension is large and the effective length is short. |
