中性轴 meaning in Chinese
neutral axis
Examples
- The equation gives the value of the bending stress at any distance v from the neutral axis .
此式给出了至中性轴任意距离V处的弯曲应力值。 - In the fully plastic condition, the neutral axis does not necessarily pass through the centroid .
在全塑状态下，中性轴不一定需要通过形心。 - The equation gives the value of the bending stress at any distance v from the neutral axis
此式给出了至中性轴任意距离v处的弯曲应力值。 - When whole analysis is carried through the beam - lattice method and bridge surface is made of box beams with one box and two cells , according to the principle of constant bending rigidity and every part revolving the same neutral axis , a box beam can be simplified into three beams in the places of corresponding webs . thus effective transfer of shearing force can be ensured , and global property can be reached through that of three beams , this kind of method is simple and is able to ensure engineering precision ; secondly , the paper is based on elastic theory , adopts finite element method and carries through the first kind stability analysis towards zhongshan no . one bridge
在选用梁格法进行整体分析时，遇到桥面系是单箱双室的箱型梁时，按照抗弯刚度不变且各部分绕着同一中性轴的原则，将一个箱型梁在相应的腹板处简化成3根梁，能够保证剪力的有效传递，而且可以由这划分的3根梁的性能得到箱型梁结构的总性能，这种方法简便易行且能保证工程精度；其次，本文基于弹性理论，采用有限元法对中山一桥进行了第一类稳定分析。 - In the higher velocity , especially in the critical velocity , the continuous model is invalidity . 2 , in this paper , assume that the track and wheels are ideally smooth and no carriage or wheel - axle bending vibrations occur . invoke the basic hypothesis of the bernoulli - euler theory of beams : namely , that plane cross - sections initially perpendicular to the axis during bending
2 、在对连续性模型的分析基础上，假设轨道与车轮为理想光滑的、没有车辆和轮轴激起的振动，引用bernoulli - euler梁理论的假设：即垂直于梁轴线的横截面在弯曲过程中仍然垂直于梁的中性轴。
