1 ?伯努利 本文先探讨了偏振光纤传感器测量ER构件的动态应变的基本原理,然后以欧拉-伯努利(Euler-Bernoulli)梁的横向弯曲振动为例讨论了一种用光纤传感网络判断一维振动的几阶振动模式的方法,进而探讨了二维情况下圆板振动模式的判断,可作... 2 ?柏努利梁 应用达朗伯(D\'Alembert)原理和欧拉-柏努利梁(Euler-Bernoulli)假设,建立了多个车辆-桥梁系统相互作用的理论模型。 3 ?努利梁 应用达朗伯(D\'Alembert)原理和欧拉-柏努利梁(Euler-Bernoulli)假设,建立了多个车辆-桥梁系统相互作用的理论模型。
- 1
An Euler Bernoulli beam equation with one end fixed and a tip mass at another end is considered. - 2
Because of the smaller ratio of slenderness, the theory of Timoshenko beam is more suitable than Bernoulli-Euler beam's for analysis of the dynamic behavior of stepped shaft. 由于这类轴具有较小的长径比,因此,在分析它的振动时,采用铁木辛柯梁理论比欧拉梁理论更为合适。 - 3
In this model, the tramcar was regarded as two degrees of freedom spring-mass-damper system, and the track was regarded as Bernoulli-Euler beam that locates on continuous and elastic ballast. 模型中,矿车被等效为两自由度弹簧-质量-阻尼系统,铁轨被等效为铺设在连续弹性道床上的伯努利·欧拉梁,矿车与铁轨的振动相互耦合。
