• Finally , a method is put forward to construct the nurbs curves on sphere , which extends the de boor recursive algorithm in r3 to one on the sphere by replacing the geodesic distances for the lines and studies their many geometric properties analogous to those in euclidean spaces , such as the differential property , the local property , the parameter invariance under a projective transformation , and so on
  两种方法均给出误差估计，使逼近螺线可达到任何预先给定的精确阶。最后，给出球面nurbs曲线生成算法：用球面上测地线? ?劣大圆弧代替直线段，将欧氏空间r ~ 3中的deboor递推算法推广到球面上构造曲线。
• Fluid noise mainly comes from out put pulsation of rate of flow , the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition . the v trough on the port plate can reduce the fluid noise . in this paper , the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12 . 3 and its length was 5mm and the cross section was an equilateral triangle
  流体噪声主要来源于输出流量脉动，造成输出流量脉动的主要原因是闭死容积在大圆弧段压力切换时产生的瞬时高压回流，在配流盘上开设v型尖槽可降低因高压回流而引起的流体噪声，本文以截流作用和液体的可压缩性为理论依据，以matlab语言为工具，对原配流盘上的v型尖槽进行了理论计算，绘制出p - t图线，分析了它的不足，并对原有v型尖槽进行了优化设计，得出了v型尖槽的最佳几何尺寸：配流盘平面上的v型尖槽的两边的夹角为12 . 3 ，槽长5mm ，槽的横截面为等边三角形。
• 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。
