1) geometrical and physical axises
几何轴和物理轴
1.
Therefore,the dynamical equations for polar motion and precession-nutation of various geometrical and physical axises have been given, including the Tisserand axis,rotation axis,instantaneous figure axis,momentum axis,CEP and CIP axis.
由此给出了弹性地球各种几何轴和物理轴(Tisserand轴、自转轴、瞬时形状轴、角动量轴、CEP和CIP轴)的极移、岁差章动的动力学方程,明确了各种轴的定义及其之间的理论关系。
2) 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。
