基于实测静力数据的模型修正方法

Model Correction Method Based on Measured Static Force Data

以桁架结构为对象,在不考虑测量误差影响下,研究了确定性模型的静力修正方法。在静力凝聚法的基础上,通过一阶摄动展开建立了关于修正因子的控制方程。通过对每个节点计算位移和实际测量位移的对比,说明了确定性模型的静力修正方法的有效性。

With the truss structure as the object,the static correction method of the deterministic model is studied without considering the influence of measurement error.On the basis of the static cohesion method,the governing equations for the correction factor are established by first-order perturbation.The effectiveness of the static correction method of the deterministic model is illustrated by comparing the calculated displacement of each node with the actual measured displacement.
