Better model for a hydraulic motor

Click For Summary

Discussion Overview

The discussion revolves around finding a better mathematical model for the torque output of Eaton 760 series fixed displacement hydraulic motors. Participants are exploring resources and methodologies that incorporate factors such as differential pressure and temperature.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Ed is seeking a mathematical model for hydraulic motors that accounts for differential pressure and temperature.
  • One participant suggests checking the MATLAB site for modeling resources, noting that many mechanical engineers utilize MATLAB for similar tasks.
  • Another participant reiterates the suggestion to explore MATLAB, mentioning that existing code examples could be adapted for Ed's needs.
  • A different participant proposes contacting MathWorks support for assistance and cautions about potential licensing costs, while also suggesting Julia as an alternative programming language for modeling.
  • Ed acknowledges the suggestions but notes that previous resources he encountered were focused on idealized models and their interactions within a system.

Areas of Agreement / Disagreement

Participants generally agree on the utility of MATLAB for modeling, but there is no consensus on the best approach or model to use, and multiple avenues for exploration remain open.

Contextual Notes

Limitations include the focus on idealized models in existing resources and the potential cost implications of software licenses, which may affect accessibility for some users.

Who May Find This Useful

Individuals interested in hydraulic motor modeling, mechanical engineering, and those exploring programming languages for technical applications may find this discussion relevant.

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.
