Revise Fluid Power Modeling?

Posted January 02, 2009 8:23 AM

A proposal to revise hydraulic pump and motor modeling into a more formalized procedure is being submitted to the National Fluid Power Association Technical Board. Applications-oriented models are being promoted for adoption by manufacturers and other users in the field of hydraulic technology. Based on experience, do you think this would be a benefit, or are the methods and experience you bring to bear adequate for your design tasks (within the time you have to do them!)?

The preceding article is a "sneak peek" from Hydraulics, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Hydraulics today.

What i am doing now has always worked, and will continue to work. But, the more resources that are available to perform the same functions more accurately and in less time would be gladly accepted.

This is one of my pet peeves about the hydraulic industry. There isn't enough modeling information to plug into a simulator so one can design instead of evolve systems. I have yet to see a transfer function for anything.

If the hydraulic industry wants to compete with servo motors then it had better be able to supply the same quality information about how the components work.

Most hydraulic designers need better design information. The bad part is that most hydraulic designers would know what to do with this information let alone have a way to use it if they had it due to a lack of hydraulic simulators.

So I have a model for a pump or a motor. What does one do with it? I know but few do.

What format would this model be in? What if the model isn't in a form that I can use in my simulator?

Could the NFPA create a standard format for modeling different parts. XML would be a good point to start.
