They are rigid, so they wouldn't vibrate, no elasticity/100% dampening, would they?

- modeless 4y agoThey won't deform but they still move and collide and that could be used to generate sound. Deformations could also be modeled by splitting parts into pieces connected by compliant joints.
- tekknik 4y agoThe sound from an engine doesn’t come from it rattling, tolerances in modern engines are very tight. Sound comes from the explosions.
- modeless 4y agoI'm sure people are interested in simulating more than modern engines with this.
- Too 4y agoDue to inertia of the piston and minor velocity difference of moving up vs down in a cranking geometry, an ICE will be unbalanced and generate vibrations. Called primary and secondary balance. This has nothing to do with tolerance, but yeah I’m not talking about rattling either, just vibrations. Unless you have a V8, where all this unbalance is cancelled out by opposing movement on the other side of the engine.
- tekknik 4y agoIt’s more to do with crankshaft design than piston count. Either way, engines have had dampeners / balancers on them since before either of us were born. So again, the sound is coming from the explosions, not the vibrations.
- matt-attack 4y agoWhat about valve clatter? I’m positive you can hear that.
- aliswe 4y agorigid means they are not jointed, i think, not that they necessarily dont vibrate...
