Hello, I’m Aldrik Brizard, with Siemens PLM Software
Today, I will introduce you with our system simulation solutions for vehicle thermal management.
Because of the global environmental regulations, the transportation industry has been pushed
to develop new vehicle powertrains,
such as downsized engine, hybrid, electric and fuel cell vehicles.
But the question is: how to handle vehicle heating and cooling?
All thermal management systems, including mobile air conditioning systems, require new
concepts to provide optimal heating and cooling, for the cabin and any type of powertrain system.
And this, while keeping control over costs and development times.
In this context, the implementation of model-based systems engineering methodologies
becomes mandatory.
Our LMS Imagine.Lab platform, and its vehicle thermal management solutions,
provide dedicated tools to build and analyze thermal behavior of complete vehicles.
And this in one single, multi-domain simulation environment.
You can model and size components and subsystems.
And you can also analyze global system performance, as well as subsystems interactions,
on both steady-state and real transient conditions. Our solutions give you the opportunity to
work on detailed models of vehicle thermal management subsystems.
For example engine cooling and lubrication systems, engine itself, air conditioning and in-cabin systems.
With our solutions, you can address various applications.
First, you can model the complete cooling system of the engine, including all the components
like the pump, thermostat and radiator.
And analyze the associated heat exchanges, and interactions, with other under-the-hood subsystems.
You can also model and design the entire engine lubrication system.
And this with all the associated components, like pumps, valves and bearings.
You can then validate and optimize systems performance,
investigate failures and study new architectures.
As a third example, our solutions help you model the overall under-hood energy balance
in a single platform, by considering interactions between thermal systems and the engine.
You can model engine warm-up and associated key criteria, such as fuel consumption and cabin
heating, on normalized driving cycles.
You can then rapidly study the influence of topological modifications on each subsystem.
The solutions also allow you to model mobile air conditioning systems and study variants,
such as heat pumps. The climate control system has a key impact on passenger thermal comfort,
and the refrigerant loop influences fuel consumption and pollutant emissions quite significantly.
You can also model waste heat recovery, through the use of Rankine cycle systems.
I will summarize by saying that LMS Imagine.Lab and its solutions for vehicle thermal management
enable you to check the overall vehicle thermal behavior, under different operating conditions
and driving cycles, while analyzing all energy flows, at vehicle level.
