二冲程发动机气流数值计算数据库技术研究

Data Base Technology for Visualized Numerical Calculation of Flow for Two Stroke Engine

讨论了二冲程发动机扫、排气道和气口气缸内气体流动数值计算可视化数据库技术，采用合理的数据结构及约束管理机制，提出了一种面向对象的数据库结构化模块设计方法．以１Ｅ５２ＦＭ二冲程发动机气体流动数值计算可视化为例，设计和开发了一个数据库管理系统．

The paper deals with the data base technology for visualized numerical calculation of flows in exhaust channels, transfer passages, ports and cylinder in two stroke engine. A design method of object oriented and data base structured models is put forward using efficient data structure and restrained management mechanism. Taking visualized numerical calculation of flow in 1E52FM two stroke engine as an example, a data base management system is developed.
