LMS Amesim is a very capable system integration simulator
and where we had a lot of tools available for
on-highway applications, we were challenged
by the availability of off-highway fuel economy
simulation capability. And for system integration,
fuel economy is a big piece of it and
with the diversity in the off-highway
applications we need a tool such as
LMS Amesim to help us to control the fuel economy
and optimize the best we can. Being a system integration tool,
it covers everything. So, therefore, we look at the fuel consumption
optimization from a global perspective.
Many of our off-highway
customers have a limited accessibility
to new tools, to new technologies. That's where Cummins can step in
as a system integrator and help them being the best they can be .
We have JVs (joint ventures) around the world and specifically
we have a JV in China which has a
lot of volume in this business
but needing support from us. So we are working diligently
with them with a high desire to exchange
the model and engine model with a system model.
So overall we see a great potential as a way to help us
expand our business to meet our financial goal.
Cummins, especially our team as a whole,
we are a little new to LMS Amesim. We started it about a year back
with our joint venture partner
based in China
the two applications which we are working on are wheel loaders and excavators.
So right now my models use planar mechanical,
3D mechanism, hydraulics, powertrain,
IFP-Engine libraries with a Simulink controller.
So with this wheel loader and excavator model, my objective is to
accomplish two things.
One is to predict fuel economy for each
machine drive cycle.
And second is the responsiveness to a command
and how the engine is responding to a hydraulic command.
Moving forward, I would like to also investigate
the use of LMS Amesim and understanding the dynamic driveline characteristics
like the mounting system, torsional system.
When you have an acceleration event, the whole driveline, that is NVH
and also more advanced, we'd like to understand
the drivability of a vehicle on the on-highway side.
So, one of the best features of LMS Amesim which I like
is the user interface and on the user interface
there comes rich libraries with a very rich competence
and a lot of physics. And it comes with a very handy set
of help which will explain what are the inputs and what are the outputs.
In some libraries you can see the physics and the references.
So it has helped me a lot because
coming from an Indian background, we do not know about hydraulics but I do
because the LMS Amesim hydraulic library, which is very rich,
can handle a pump or DCV or any relief valve
or any kind of functionality. We started working with LMS Engineering services a
couple of months back and it has been great
and there are to the point, very sharp, they know what they're doing
and it has got me a spare project space
otherwise I would have been struggling
for a couple of months but they fixed it
in a few weeks, so I'm pretty happy , very satisfied.
