曲线分段 meaning in English

curve segmentation
segmenting a curve

Analysis of archimedean spiral antenna using moment method with curved segmentations
曲线分段的矩量法分析阿基米德平面螺旋天线
The principle of the predigestion in geometry modeling is omitting the function part and the non - load - carrying process structure , and to the big and transition arc , the curve is replaced by straight line using the thought of curve and free - surface segmentation . the physical characteristic of the digital model reflect on remaining the main mechanical characteristic of the objects . the shell element model is used in strength analysis , stiffness analysis and dynamic analysis
文中几何建模的简化原则是,略去功能件和非承载的工艺结构,对于大圆弧和过渡圆弧,以曲面分块和曲线分段的思想进行适当的以直代曲;数模的物理特性反映在最大限度地保留对象的主要力学特性;在强度、刚度和动态分析中采用壳元模型,轻量化设计中采用梁元模型;材料特性根据所用材料定义其主要性能参数。
