柴油机特性试验的计算机模拟

Computer Simulation of Diesel Characteristic Test

为了提高教学效率,优化教学过程,加强实验技能培养,本论文结合学校硬件和软件情况采用Visual Basic语言开发了柴油机特性试验软件系统平台,为学生提供了一个人机交互、界面友好的学习试验环境。本系统是采用Visual Basic语言构建了柴油机特性试验软件系统平台,可以进行柴油机负荷特性和速度特性试验,学生可以选择不同的试验类型,不同的柴油机型号,以及试验中的不同的过程参数进行试验,得到相应的试验数据绘制出负荷特性曲线,速度特性曲线和万有特性曲线,进而方便学生分析参数间的变化规律来评价柴油机的性能。

Combined the hardware and the software of the school, this paper researched diesel en- gine characteristic test software system. And this system provided an opening surrounding of person-computer alternation and friendly interface. The diesel engine test software system was established based on Visual Basic algorithms in this paper. It can test diesel engine load characteristic and velocity characteristic. So that the students can choose different test , different diesel engine and parameters in order do some tests. Then they can got data of the test and draw load characteristic curve, velocity characteristic curve and universal characteristic curve. Moreover it is convenient to students to analyse changes of parameters and evaluate performance Index of diesel engine.
