Anyone in this group using easy to use (and affordable) FEA analysis tools with Rhino?
I need to examine some physical capabilities of some designs. I’ve been looking around a bit and software do exist out there (…), but most of the more capable FEA packages seems to be way more expensive than my (private) budget would allow.
Of course my needs determines more exactly what software would be useful, so here’s what I think I need to simulate (during rotation). Think of a ten (10) ton heavy rotating steel clutch :
- Rotate with high torque (say, 8 MW, 100+kNm at 700 rpm).
- Friction from alternative bearing types: Plain bearings/surfaces, ball bearings (both axial & radial types), or needle bearings.
- Estimation of heat generation from friction (see bearings above).
- Heat convection and dissipation,
- Tolerances (deformation allowance) for parts sliding against
each other under radial torque as well as axial load.
- Frequency/resonance (impact from unbalanced parts) etc.
Apart from optimizing the part design I need to arrive at reasonable “design parameters” for engineers, given input requirements (example above), and in some cases axial loads. With “reasonable” I mean useful for prototype dimensions.
Of major concern is how different types of bearing solutions (plain, ball, needle) impacts performance and design parameters, and thermal effects on tolerances.
I am not a mechanical engineer and no former experience of FEA analysis, which is why good learning material matters.
Mesh generation and CAD integration (iterative adapting of the design) seems to be an issue as well. Apart from pricing.
