Multi-physical contact simulation in Vehicle applications

Popis výsledku v původním jazyce

Multi-physical contact behaviour is important in multiple disciplines related to the automotive indus-try. Nowadays battery-electric vehicles’ (BEV) thermal management systems deal with contact be-tween bodies where mechanical, electric, and thermal interaction occurs. The battery thermal manage-ment itself is crucial for cell life, safety, and everyday vehicle performance. Thus, comprehensive and accurate simulation of the multi-physical contact is a vital part of vehicle development. The multi-physical contact is represented by two or more bodies under applied mechanical load and a current or heat conducted throughout the realized contact area. The amount of conducted current/heat or gener-ated Joule heat is the function of the contact area as well as contact pressure, thus the structural simu-lation should be essential for such thermal management system simulations Most of the current full vehicle battery pack CFD cooling simulations simplified the multi-physical contact as ideal. Detailed contact modelling is time-consuming, hence not applicable for the full vehicle modelling. In this work, a feasible approach based on contact resistance curves was implemented. Furthermore, the work demonstrates the necessity of correct structural contact prediction for a joule heating and thermal so-lution.
