centre

The centre of circle is decided by Matlab soft.

针对圆形工件合格性检验问题建立了两个优化模型,运用Matlab软件进行编程求解,确定了圆心的位置,据此判断出工件一为正品,工件二为次品。

Considered the geometric and material non-linearity , this article analyzed some factors which influence the ultimate bearing capacity of welded I-section with S-shape curved beam , such as point of knee bend、central angle、ratio of width-thickness of web and ratio of width-thickness of flange.

采用有限元分析软件Ansys,对一焊接工字S形钢曲梁的稳定极限承载力进行分析,考虑几何和材料的非线性效应,对影响S形曲梁稳定极限承载力的拐点、圆心角、腹板高厚比和翼缘宽厚比等因素进行了较全面研究。

To find out the laws of how the elastic and plastic mechanical behavior for prestressed concrete curved continuous beams are influenced by central angle,a series of prestressed concrete curved continuous beams are simulated based on the theory and the program of prestressed concrete curved beams.

圆心角是影响曲线梁力学行为的重要因素。
