而常规的这类桥梁计算的有限元分析中，并未考虑（引入）吊索（杆）系的几何刚度矩阵。 - The task consider geometry stiff matrix of suspenders due to adjustment of suspender length ( the actual suspender length is shorter than its nominal length ) , and derive method and step of static tension of suspenders from single order variation
本课题还考虑了由于吊索（杆）长度的调整（实际的吊索（杆）长度比名义长度短）而引入的吊索（杆）系的几何刚度矩阵（初应力刚度矩阵） 。 - The application of finite element method ( fem ) to dynamic stability analysis is described emphatically . the lagrangian equations is used to derive the necessary element matrices ( element stiffness matrix , element mass matrix and element geometric stiffness matrix )
着重论述了有限元法在动力稳定问题中的应用，并采用lagrangian方程推导出单元矩阵的表达式(单元刚度矩阵、单元质量矩阵和单元几何刚度矩阵) 。 - Through analysis in theory and calculation on real cable - stayed bridges , following conclusions have been reached : 1 ) methods of modeling cable - stayed bridges for nonlinear finite element analysis are reasonable and effective and truss and beam element has enough accuracy
通过理论分析和实例计算，本文得出了以下结论： 1 )本文在杆单元中用等效弹性模量来考虑斜拉索的垂度，考虑梁和塔中的梁、柱效应以及修正几何刚度矩阵是合理的、有效的。 - The temperature effect which has been calculated is taken as " thermal load " forced on the body , then such thermal stress is settled as general elasticity mechanics question ; secondly , the thermal stress is taken as " surface force " forced on the body , and the new system stiffness is formed which include the extra stiffness matrix , then it changes the nature frequency of the structure
首先，这篇论文介绍温度场和热应力场的有限元方法，建立了三维热传导模型计算有温度场产生的热应力，计算热应力时运用了一种转化思维：将温度处理为“温度载荷” ，这样就能用弹性力学问题的处理方法来求解热应力。其次，将热应力作为结构的“面内力” ，而面内力产生附加的几何刚度矩阵，改变了结构的刚度，影响了结构的固有频率。
