Because the service life of the end lining ofφ2.7×3.6m primary ball mill is too short to equte to that of the shell lining, the paper breaks through traditional design mode and greatly increases the service life of the end lining by means of scientific design, application, optimization and finalization in case of tapping the service potentiality of the material fully
The difference between traditional design mode and modern design mode is given. The method that virtual prototyping is used in high power laser design is presented. The manufacturing information integration of CAD/CAE/CAM based on Virtual prototype is given, too.
The experimental result demonstrates that the design method in this paper owns good effect and practical value,which has realized the integration of least response time and the minimum resource cost. Especially under the circumstances that the average speed can meet the processing demand while the speed of burst of interrupt message exceeds the processing ability of the system,this solution solves the problems of low response speed in traditional design mode and data losing.
Among the woven,jacquard fabric belongs to a variety of higher end in technological sense. Its structural design is the key in designing the fabric, and one to one corresponding principle is always regarded as one of the most important principles,which is the foundation for creating innovative designs of jacquard fabric under with either the traditional design mode or computer aided design mode.
This article has discussed the characteristics of modern mechanical engineering design and the development trend of CAD, which is very significant in understanding the new trend, development and applying new technology and reform traditional designing mode.
This thesis analyses the characteristics of traditional designing mode and limitation design mode, and proposes a new cost-oriented mode of construction project design, which has the characteristics of incorporating cost control into designing and forming an integrity with engineering design.
本文分析了传统设计模式、限额设计模式的特点,运用DFC(Design For Cost)原理提出了面向造价的建设项目设计工作新模式,该模式的特点是将造价控制工作渗入到设计工作之中,与工程设计形成一个密不可分的整体。
Moreover, not only is this new depicting method able to cover the shortages of traditional deign pattern in description of dynamic information, it can also conform numerous design patterns to the specifications, thus enabling them better understood ,recognized and managed by the users.
Based on the analysis of every kinds of highway asphalt site construction status and traditional desion method. introduced the design features and the practical application results of heating asphalt locally technique, presented some proposal of asphalt site with every kinds of purpose,scale and form.
A rational cubic spline curve to describe highway alignment is introduced. Select parameters of spline function to determine highway alignment preliminary scheme. Then selecting parameters again, we can express the alignment's line, arc, transition curves through the variations of parameters. This method is unanimous from traditional design method and can complete alignment design of three dimensional highway CAD quickly.
This paper puts forward an analytic design method of the scheme of moving functions in a robot for machining, with taking the working surfaces and cutting tools as input information.The method breaks through the traditional design mode, and provides a theoretical base for the concept design of a robot for machining.
