straight beam element meaning in English

直梁单元

Based on the structural feature of long blade with friction damper , pretwist beam element and space straight beam element were adopted to discrete the blade , and the numerical model of damper link element was established , then the gross finite element motion equation of the blade was obtained
针对带摩擦阻尼器长叶片的结构特点，采用扭曲梁与空间直梁单元模化叶片，推导叶片阻尼连接单元的力学模型，由此建立叶片总的动力特性分析方程。
In the analysis , a cfst arch ( single tube ) is first divided into a finite number of straight beam elements . according to the virtual work principle and the modified newton - raphson iteration method the tangent stiffness matrix considering double nonlinear properties is established . with regard to the non - equilibrium forces , the material nonlinear property along the height of the section and the length of the element is considered and the computation accuracy is improved as a result
本文首先将拱肋划分为一系列的直梁单元，运用虚功原理和修正newton - raphan数值迭代算法的基本原理准确推导了拱肋直梁单元的非线性切线刚度矩阵；在不平衡力方面考虑了沿截面高度和单元长度方向材料非线性的发展过程，提高了计算精度；再根据得到的切线刚度矩阵采用荷载增量步内修正newton - raphan迭代的增量迭代法进行了求解。
