Traditional engine design method is experience design method , since 1980s , many modern design methods , which are limited in the static design category , have been taken 传统的发动机设计方法是经验设计法,八十年代以来采用了许多现代设计方法,但大都局限于静态设计的范畴,对于日趋严酷的设计指标,静态设计已难以满足要求。
This thesis primarily concentrates on the engine of flexible workflow management system . the engine design is discussed , key techniques of the engine are investigated and the implementation of the engine is given 本文重点研究柔性工作流管理系统的引擎部分,详细论述了引擎的设计,研究了引擎的关键技术,给出了引擎的具体实现。
Manipulating high - resolution interactive graphics in engineering , such as in aircraft engine design , has always been a challenge in terms of performance and scalability because of the sheer volume of data involved 在工程领域(例如航天引擎设计)操纵高分辨率的交互式图像在性能和可伸缩性方面历来都是一种挑战,因为这要涉及大量的数据。
A fluid - thermal - structure coupled analysis technique needs to be developed for advanced engine design . presently , fluid flow and heat transfer is mainly analyzed using finite volume method ( fvm ) and structural deformation is often solved by finite element method ( fem ) 由于历史原因,目前在流体流动和传热分析中广泛采用的是控制容积法,而在弹性变形的分析上采用的是有限元法,并分别发展了相应的工程应用软件。
The cfd analysis on the diesel engine ' s intake port is very important in the diesel engine design and produce . it will economize so much time and money which iiad been used in steady flow experiment . it shortens the time from design to experiment and to produce in the end very much 柴油机进气道的cfd分析对柴油机的设计和生产起着举足轻重的作用,它可以节约大量原本应用于稳流实验的资金和时间,大大缩短产品从设计到实验再到最后投入生产的周期。
