It ' s extremely difficult to draw a long line on curved surface with brush pen . look at this smooth line , not easy 用毛笔在极小的弧面上拉长线条难度是极高的，看这线条依然流畅，不容易！
Furthermore , the paper constructs a 3d cad software of two different structures of gcm using the redevelopment module of ug 利用ug软件的二次开发模块开发了两种不同结构的弧面凸轮的三维cad软件。
The primary coverage as follows : firstly , according to the running features of the globoidal indexing cam mechanism establishes mathematical model , then builds overall design 主要内容如下:首先根据弧面分度凸轮机构的运行特点建立数学模型,并进行总体设计。
The result indicates that this program is safe and reliable for pdew fuzzy optimization . the researching in this paper has been obtained some worth in fuzzy optimization design and motions of pdew 以某橡胶厂轮胎硫化机弧面蜗杆减速器为例，验证了该模糊优化设计程序，结果表明该程序运算准确可靠，优化结果可行。
Taking practical situation of this project and much engineering experience into account , the scheme with axle golden section elliptical arc surface is proposed through comparing nine optimization schemes with model test 结合工程实际和以往经验，比较了9种进水口曲线型式的试验结果，确定了长短轴黄金分割比的椭圆弧面的方案。
Globoidal cam mechanism ( gcm ) was invented by c . n . neklutin , an american in the 1920s . ussr , u . k , hungary , switzerland and japan began to study it successively , and founded special academy agencies and manufactories 前苏联、英国、匈牙利、瑞士、日本等国也相继对弧面凸轮机构进行了研究，并成立有专门的生产厂家和研究机构。
Focusing on present defects of cnc milling machine tools specializing in machining the roller gear indexing cam , two design projects of simultaneous five - axis movements of cnc milling machine tools specializing in machining the roller gear indexing cam are raised 摘要针对当前国内弧面凸轮加工专用数控铣床的缺陷，提出两种五轴联动的加工弧面凸轮专用数控铣床的设计方案。
Though our country was late to study it , which began until the late 70s , we have acquired great progress in the design , examine , manufacture of gcm , especially in the explore of its novel structure 我国对弧面凸轮机构的研究起步较晚，直到70年代末期才开始相关的研究工作，已在弧面凸轮的设计、检测、制造等方面取得了丰硕的成果，特别是对新型结构的弧面凸轮进行了大量的探索。
In a word , the paper provides an visible software operation platform for the analysis and design of globoidal indexing cam , builds primary model of the mechanism dynamics system , then provides references for the mechanism ' s deep research 最后对弧面分度凸轮机构动力学系统的主要特征进行了分析，并建立考虑构件惯性，啮合刚度及参数激励的条件下的弧面分度凸轮机构的振动分析模型。
And meanwhile the movement of the mechanism is simulated using the pro / mechanism module of pro / engineer . in this paper , studies on the characteristic of the cam dynamics system and vibration model of the system are done , which provides a foundation for the further researches 为了便于观察到凸轮机构在各位置和各种角度下的运动情况，还利用pro engineer中的pro mechanism模块实现了弧面分度凸轮机构的运动仿真。
