Balance of I.C.Engines

Collection of 3D animations about balance and cranktrain configurations of several kinds of internal combustion engines:
2stroke 2cylinders inline,
4s. 2-4-6cyl. inline,
4s. 2cyl. boxer,
two versions of V8,
V12,
the old W9 and new W16
and a 5cyl. radial engine .
Done using 3d studio max for a univ. project...

Sorry but the W16 at the end contains an error in the crankshaft - I'm working to fix it.

Animazioni 3D sull'equilibrio delle forze d'inerzia di alcune configurazioni di motori a combustione interna:
motore 2tempi 2cilindri in linea,
4t. 2-4-6c. in linea,
4t. 2c. boxer,
due versioni di V8,
V12,
il vecchio W9 e il nuovo W16
e un 5c. radiale .
Realizzato con 3d studio max per un lavoretto di meccanica applicata...

Scusate ma mi sono accorto che il W16 alla fine contiene un errore; verrà sistemato al più presto (o quasi)

Why not shown the forces and moments for the higher order arrangements, e.g. V-8 and up?

[streincorp]

@Boentgru

Technically the inertial forces of a Vee should be the same of its respective inline engine, because their crankshafts have the same shape. So V8's forces and moments are the same of a 4-inline and the V12 the same of a 6-inline.

Anyway, the different arrangement of pistons can add little components to the forces, but these are often unimportant.

What do the blue arrows represent?

[streincorp]

@BeauKnight96

The blue arrows are the second order inertial forces (first order in red). The rotation of these vectors is only a mathematical representation of an equation containing two harmonic functions.

[frankydevaere]

I thought inertial forces ( first and second order ) fluctuated between zero and maximum.

Very nice animations by the way !

[streincorp]

@frankydevaere yeah, thanks.

and you can see this fluctuation like the projection of a vector in rotation

[BeauKnight96]

@streincorp thank you. and great video!

Intense music... im gettting really excited.

Cooool

@WShowduh translate this Italian in english: gira più veloce perchè le forze del secondo ordine si muovono al doppio della velocità angolare, rispetto a quelle del primo.

[mattbeatle8]

@WShowduh these are the two equations of 2nd order forces and moments balancing
