摘要:

以超静定结构支架为研究对象,建立力学模型,以静力学平衡方程为基础,在分析支架受力及变形情况的前提下,利用变形协调条件和力与位移间的物理关系建立变形补充方程,求解微分方程组后得到支架的受力情况。该计算方法与仿真分析所得结果基本吻合,偏差在允许范围内。将该计算方法与传统估算方法进行对比,该方法适用范围更广、结果更准确。

Abstract:

Take statically indeterminate structure support as study objective, mechanical model was designed. Based on static equilibrium equation, the stress and deformation of on the analysis of the support under the premise of using force and displacement condition of deformation coordination and supplement the physical relationship between deformation equation, the force situation of solving differential equations and obtain support. The calculation method is consistent with the result of simulation analysis, and the deviation is within the allowable range. The calculation method is compared with the traditional estimation method, which is more widely used and more accurate.
