Better model for a hydraulic motor

[edwaugh]

Hi all,
We are doing some work with Eaton 760 series fixed displacement hydraulic motors and are looking for a better mathematical model for the torque output. Does anyone know a good place to look? Something that includes differential pressure and temperature would be ideal.
Thanks
Ed

Have you checked on the MATLAB site? A lot of ME folks use MATLAB to do these kinds of modeling.

MATLAB has a lot of code examples that you might be able to cobble together a model suited to your needs.

Thanks I will take a look. The things are saw so far focussed on quite idealised models and how they interact in a whole system.

You could post a query on mathworks or call their support citing an interest in their product to do your modeling and see what they say.

Be aware that a license may cost much more than a student license.

Another possible avenue is to look at Julia programming. It’s quite popular for modeling and has many libraries that support differential equations. Julia is and open source programming language and was developed by MIT folks.Perhaps a post on their discussion forum will yield some help.
