Design and calculation on work clearance and relative interference amount of non-backpressure piston rings;

无背压活塞环的工作间隙和相对过盈量的设计计算

The formula of thermal expansion work clearance between piston ring and cylinder inner side was derived by thermal deformation analysis.

利用热变形分析推导出了活塞环与气缸内壁间的热膨胀工作间隙计算式,表明工作间隙与非金属环的线热膨胀系数和工作前后温升成正比。

Simulation model of MTU 396 diesel generator by using Simulink,the Matlab RTW transforms Simulink into transplanted embedded C++,the diesel generator set speed control hardware-in-loop simulation is developed in Visual C++.

通过Simulink建立MTU396柴油发电机组的仿真模型,然后采用Matlab实时工作间(RTW)将Simulink仿真模型转化成可移植的嵌入式C++代码,最后在Visual C++集成开发环境下开发柴油机发电机组转速控制半物理仿真系统。

The model has been converted to generic real-time coder program by RTW (real time workshop).

利用RTW(实时工作间)将模型转化为通用实时代码,加快了仿真速度。
