This thesis, first, reviewed the development and present situation of the fields correlative with nc dynamic design, indicated the target and values of the thesis, and stated the chief research content of it 本文主要包括以下内容:1.综述了数控机床动态设计相关研究领域的发展状况,阐述课题提出的目的和意义,明确了本文研究的主要内容。
The paper's design mainly includes two parts . fist part is the tappet displacement curve's design, and many dynamics calculation has to be done based on the dynamic design . second part is to design cam profile curve 本文的设计主要包括两大部分,第一部分为挺柱升程曲线的设计,按照动态设计要进行大量的动力学计算,第二部分是凸轮轮廓曲线的设计。
dynamic design method get very good social benefit, economic benefit in our work . although dynamic design can not solve this kind of status, but we at least can find a method, it can face requirement change, and welcome this kind of change “动态设计”方法,在实际工作中,收到了良好的社会效益,经济效益,本论文的第四章详细描述其在实际工作中的应用情况。

New austrian tunneling method combined with field monitoring measurement are employed in the currently-built twin-arch tunnels to conduct dynamic design and information construction, which brings about fruitful economic and social benefits 目前建成的各类双连拱隧道,采用新奥法设计施工,结合现场的监控量测,进行动态设计,信息化施工,产生了很好的经济和社会效益。
On the basis of brief description of the traditional belt conveyor design method, the dynamic design is performed to attain optimization of system parameters as well as increase in stability and economy 摘要在带式输送机常规设计的基础上,应用动力学理论,以优化系统参数、增强稳定性和提高经济性为目的对带式输送机进行动态设计,通过实例分析说明动态设计的必要性。
From the angle of dynamic design and information construction, a displacement back-analysis method which applies monitor information to determine soil properties and direct design and construction of slope excavation is found in this paper 本文从动态设计和信息施工的角度出发,建立了将现场监控量测信息用于确定深挖路堑边坡土体参数和指导设计与施工的位移反演方法。
Aiming at control of crack of this structure, it was put forward that design of concrete structures with large longitudinal length should be integrated with actural material characteristics and construction process to realize a dynamic design 对长期试验的结果分析得到一些结论,针对超长预应力混凝土结构设计中的裂缝控制提出应结合混凝土的材料性能及实际施工过程,实现动态设计的建议。
Thirdly, during the design of the secure system, the logical fabric of network security system is pointed out . it shows the all-sided, dynamic design idea with technologies of static protection ( eg . firewall, acl, digital encryption ) and active secure detection ( eg 其次,结合网络特点,分析现实网络安全需求,以p~2dr安全模型作为理论指导,按照padimee方法论,确定重庆公众ip网的安全策略。
On the design of the material library, the concept of micro-unit material that all kinds of materials are turned into micro units is introduced, and the advantage of using this micro-unit in the dynamic design and auto generation of the courseware is very obvious 在素材库的设计中,提出了素材微单元的概念,把各种素材最小单元化,素材微单元化应用在课件的动态设计与生成过程中,优势发挥更明显。
