Simulating Thermal Balance of Electronics – an AcuSolve approach

Knorr-Bremse as a supplier of brake systems for rail and commercial vehicles develops electronic devices which are part of virtually all modern rail-bound mass transit systems like Metros, High-Speed Trains or Light Rail vehicles. Electronic devices are furthermore responsible for various processes onboard, including safety critical functions like brake control, door units or emergency systems. To ensure the proper function of electronic brake control units under demanding thermal environmental conditions, Knorr-Bremse uses simulation techniques including AcuSolve in India and other CFD tools worldwide. With the use of AcuSolve it is possible to estimate the air temperatures inside of 19-inch electronic brake control units for different mechanical design, equipment, power loss and environment temperature scenarios. Integrated in the product project development process, this helps to reduce hardware test effort, increases quality and development/project output speed at Knorr-Bremse.
