In chapter 4 , for the first time , in the way of virtual malfunction simulation , cooling water of diesel engine type 4135 has been simulated under the stopping water supply malfunction . and the analysis and discussion has been taken on the result of transient temperature curve of the simulation . and in the same way , internally cooling oil piston of diesel engine type 180 has been numerically simulated on the virtual thermal loading mal 得出了虚拟其断水故障仿真的瞬态温度曲线结果，并对其进行了分析和探讨；同时也用虚拟仿真的思想对180型柴油机内油冷活塞进行了虚拟其热负荷故障的数值仿真，得出了其在断油情况下和超负荷运转情况下的分析结果。
Based on a reduced - order model , the vsc of flexible rotor - magnetic bearing system is also investigated . a master - slave controller composed of a pc586 and a tms320c50 dsp board is build and a flexible rotor - magnetic bearing test rig is developed . simulation and experimental results show that the vsc is insensitive to the spillover problem due to the model truncation and parameter uncertainty 结果表明,变结构控制器对于因模态截断及非并置问题导致的未建模动态以及因系统自身特性变化而导致的参数摄动具有不敏感性,系统在上浮过程、受到外界扰动及复杂运转情况下的性能均优于pid控制器。
Almost all of the enterprises currently hope to extend the function of mis to support production management . the core of production management is to know the running state of streamlines or furnace devices through real - timely observing the running parameters of them at long - distance , in order to guarantee these devices running normally to avoid the production abnormity 现在几乎所有的企业都希望将mis系统的功能进行扩展,企业生产管理的核心是对流水线或机炉设备的运转情况的了解,希望能够实时地远程观察到设备的各种运行数据,以保证设备的正常运转,避免生产的异常。
