The curve plotted in this way would meet the boundary conditions given and all the polar curves embodied the same wrapping angle 这一方法不仅保证了绘制的型线有给定的边界条件,同时保证了各型线有相等的包角。
The air inlet noise is related to designing factors like the air inlet mode , the inlet valve structure , the cylinder diameter as well as the cam curve 进气噪声与发动机的进气方式、进气门结构、缸径、凸轮型线等设计因素有关。
So it is significant to study the principle and key techniques of nurbs and apply them to the practice of ship lines design 因此,深入地研究nurbs的机理和关键技术,并将nurbs方法应用于船舶型线设计就成为造船设计中一个非常重要的内容。
The optimization parting direction was determined after all undercut features were distinguished , and the parting line and parting surface were confirmed accordingly 通过侧凹特征的判别确定模具的优化脱模方向,并确定模具的分型线和分型面。
This paper deals with optimal design of high power function cam profile of the sl1115 diesel engine ? a newly developed single cylinder diesel engine with dual connecting rod 本文研究了一种新开发的单缸双连缸柴油机sl1115的配气凸轮型线的优化设计。
The paper mainly introduces the calculating equation for piston skirt molded lines , the drawing of piston , and the design for convexity mother plate molded lines 摘要重点介绍了计算活塞裙部型线方程,给出了从图纸到中凸靠模板曲线板型线设计的方法。
