摘要:

以三个移动和三个转动自由度的空间直角坐标推导了空间弯曲和扭转形杆的一系列基本方程式,通过解决应变为常量和零时的位移与应变关系。建立了形杆的刚体和常应变模式.以位移为基本函数,形成了单元的有限元模型。分析了三个自由振动的例子,计算结果与实测值十分一致,证明了公式和单元矩阵的正确性。

Abstract:

A series of basic equations that use three mobile and three -rotating freedom spatial right -angle coordinates to derive space bending and torsional rods, and the relationship between transformation and zero -time displacement and zero -time displacement and strain. The rigid body and normal strain mode of the shape rod are established. With the position of the position as the basic function, the unit’s finite element model is formed. The three examples of free vibration are analyzed. The calculation results are very consistent with the actual measurement value, which proves the correctness of the formula and unit matrix.
