Modelling and Validation of a Truck Cooling System
In the future, new challenges will occur during the product
development in the vehicular industry when emission legislations
getting tighter. This will also affect the truck cooling system and
therefore increase needs for analysing the system at different levels
of the product development. Volvo 3P wishes for these reasons to
examine the possibility to use AMESim as a future 1D analysis
tool. This tool can be used as a complement to existing analysis
methods at Volvo 3P. It should be possible to simulate pressure, flow
and heat transfer both steady state and transient.
In this thesis work a cooling system of a FH31 MD13 520hp truck with
an engine driven coolant pump is studied. Further a model of the
cooling system is built in AMESim together with necessary auxiliary
system such as oil circuits. The model is validated using experimental
data that have been produced by Volvo 3P at the Gothenburg facility.
The results from validation and other simulations show that the model
gives a good picture of the cooling system. It also gives information
about pressure, flow and heat transfer in steady state
conditions. Further a design modification is done, showing how a
change affects the flow in the cooling system.
The conclusion is that a truck cooling system can be built and
simulated in AMESim. Further, it shows that AMESim meets the
requirements Volvo 3P in Gothenburg has set up for the future 1D
analysis tool and thereby AMESim is a good complement to the already
existing analysis method.
