can anyone show me how to design a wave spring that have .550 ID. by 2.25 OD. by .312 high, 5.5 to 6.5 LBs/ square inch
I think this is a buy, rather than a make.
Google "Custom wave spring", and find a manufacturer to work with on this.
I have personally worked with Smalley--they are excellent. There are a number of other companies that are set up to design and manufacture this component to your spec. They make a living doing this, because it's relatively easy for them and relatively difficult for you. It can certainly be done, but still.

I just saw a SolidProfessor tutorial that showed how to do this, literally within the last week. You might be able to search their site and find it. It was very well done, as is all their stuff.

I had to do one about 5 years ago and I ended up sketching rectangles on equally spaced planes about a center axis with every other rectangle positioned higher than the one before and after, I then lofted the sketches. I don't know if it's the best way to do it but I only had to do it once so it didn't really matter. I'm sure somebody has a more elegant way to do it.
Im not sure if this is what you are after, but here is the SolidProfessor tutorial mentioned above.
I followed it and it works great, you should be able to change the values to get something like what you want.
There are a lot of helpful posts here about how to model a wave spring. That's an interesting problem. But I think the real challenge is to get the spring constant within 5.5-6.5 lbf/in. That is a much harder problem, and I think the OP would be better off handing that to a professional who can do it cheaper and easier.
