摘　　要：为了研究涡轮增压器动态性能,在Simulink环境中采用模块化结构,建立了涡轮增压器热动力试验台的涡轮、压气机、燃烧室、阀和控制系统的数学模型。其中为了模拟压气机喘振和旋转失速现象,压气机特性图被延伸到负流量区域。将模型下载到dSPACE实时仿真平台,并模拟了采集压气机特性和涡轮特性曲线的动态过程以及压气机喘振状态。其仿真结果:初步确定了增压器热动力试验台总体方案及其控制系统原型,并预测了增压器喘振过程的压力、流量和转速的振荡,对实际台架的安全性有重要的指导意义。In order to investigate the dynamic behavior of the turbocharger, a model of the turbocharger test was established using Simulink module, This test comprises the turbine、 compressor, combustion chamber, throttle and controller. To model compressor surge and rotating stall, the compressor map was extended for the negative mass flow. A time delay was used for taking into account the departure of the compressor characteristics for their steady state. The model was downloaded into the dSPACE real-time simulation platform. The compressor surge and the transient process were simulated that the compressor map and the turbine map were measured. The rapid control prototyping of the turbocharger test was produced with dSPACE Systems. The pressure and speed oscillations during the compressor surge were predicted. That can avoid damages on the components of the test before installing a new turbocharger on an existing test rig.
