geometric central axis几何中轴
1.Based on the hypothesis of planar cross-section and the geometric central axis taken as the reference axis,the curvature-the axial force and the moment equation of the geometric central axis subjected to both a axial force and a moment is derived on the occasion of the large deflection,and the system of equations for solving the deformation of the geometric central axis is established.以平截面假定为基础,并以几何中轴作为梁变形的参考轴,推导了大挠度情况下,弹性梁在轴力和弯矩联合作用下几何中轴的曲率——弯矩和轴力方程,并建立了求解几何中轴变形曲线的方程组,这样的方程组考虑了梁轴向变形的影响,克服了以中性轴作为梁变形参考轴时不能考虑轴向变形的不足。
