摘要

提出通过高精GPS进行起重机臂架挠度测量、多维插值实时计算挠度以及基于拟合曲线的起重机臂架挠度形变显示方案,能够实时地进行臂架挠度形变的动态计算和三维模拟,使吊装仿真过程更加符合实际工况,从而能在一定程度上提前规避由于挠度形变所导致的安全性问题.%The paper proposes a solution of measuring deflection of crane boom by using high-precision GPS, calculating deflection by means of multi-dimensional interpolation in real time and displaying deflection deformation on the basis of fitted curve. The scheme allows dynamic calculation and three-dimensional simulation of deflection deformation in real time, thus making hoisting simulation closer to actual conditions and helping avoid security problems resulting from deflection deformation to some extent.
