车辆热管理

在汽车行业,设计工程师经常面临物理和控制系统复杂的多领域交互问题。特别是整车热管理(VTM)。

无论是,车辆工程师可以使用Dymola和Modelica库,用基于模型的系统工程(MBSE)的方法,有效地进行机舱或发动机的热管理分析和燃油效率的研究分析。

Dymola的和的Modelica库中的MBSE方法为用户提供了一个综合的多物理平台,从而减少了协同仿真的时间消耗。同时为各种结构的车辆提供了从ICE到电动以及同时进行瞬态和稳态的模拟。

优点

  • 缩短了测试时间和成本。
  • 在设计早期进行系统性能分析,更容易修改模型,且成本低廉。
  • 与所有其他Modelica库兼容,可实现模型重用和扩展。

Integrated Vehicle Thermal Management in Modelica

This presentation highlights the use of a coordinated suite of Modelica libraries for vehicle thermal management applications.

Model-based systems engineering (MBSE) is used to reveal the complex, multi-domain interactions between physical and control systems over drive cycles for combined thermal and fuel-efficiency studies. The common model is also used to support controller development and optimization as an FMU integrated into Simulink. 

The flexibility of FMI-based workflows is illustrated via batch and Monte Carlo simulations in Excel. A heat exchanger application coupling inputs from CFD illustrates the use of higher-fidelity models from the Heat Exchanger Library for calculation of performance degradation due to non-uniformity.
