Hey all, here is an animation I created in autodesk inventor. If anyone is doing a similar project for an engineering graphics course I could give some pointers such as constraining parts, creating the epitrochoid shape, etc.

Its a pretty basic representation. I would have liked to model it more realistically, but I ran out of time. The dimensions are loosely based off of the 12a engine.

damn that pretty good job. How long did it take you?
Was this for an undergraduate course?

 

Any reason you can’t finish it to your desired specifications now?

A little time applying materials and lighting would improve presentation exponentially

 

Neat, nice work.

 

Thanks for the replies. It took quite a while to constrain the different parts. I created a much simpler one rotor version to figure out if it was possible. Once i got that working I created the two rotor version and animated it in about 2 days working 8 hours each. This was for an undergrad class.

I could certainly go back and apply different surface styles with bump maps, but the PC I have at home is so slow it might take months to render. Also, now that I'm home from school I get to work on my real rotary engine!

 

very impressive

 

Nice. Animate what happens if an apex seal goes :p
