Within the scope of this work, a multi-domain system modeling approach that is compatible with various electronical components and subsystems used in automotive and railway applications is to be developed. This approach serves the development of a hybrid, model-based condition monitoring of complex electronic and mechatronic systems. It aims at the implementation of condition monitoring in relevant applications of automotive and railway technology, e.g., safety-relevant electronic systems for train control and control units of electrified automobiles. Furthermore, the multi-physics modeling of the mentioned electronic components is performed using different object-oriented simulation environments, such as Simulink and OpenModelica¹ in order to obtain as much information as possible that is relevant for the reliability assessment of the modeled systems. The approach is applied on two common example circuits used in complex electronic systems, a clocking circuit with a crystal oscillator and a full-wave bridge rectifier circuit. Moreover, the investigated circuits as well as the degradation behaviour under external loads during the operational lifetime in order to model the functionality are demonstrated.

在这项工作的范围内，将开发一种与汽车和铁路应用中使用的各种电子元件和子系统兼容的多域系统建模方法。这种方法服务于复杂电子和机电一体化系统的基于模型的混合状态监测的开发。它旨在在汽车和铁路技术的相关应用中实施状态监测，例如用于电动汽车的列车控制和控制单元的安全相关电子系统。此外，上述电子元件的多物理场建模是使用不同的面向对象仿真环境进行的，例如 Simulink 和 OpenModelica ¹为了获得尽可能多的与建模系统的可靠性评估相关的信息。该方法应用于复杂电子系统中使用的两个常见示例电路，即具有晶体振荡器的时钟电路和全波桥式整流器电路。此外，为了对功能进行建模，还展示了所研究的电路以及在工作寿命期间在外部负载下的退化行为。
