ʻO ka neʻe ʻana o ka crankshaft torsional a me ka harmonics

I kēlā me kēia manawa e puhi ʻia kahi pahu pahu, hāʻawi ʻia ka ikaika o ka puhi ʻana i ka crankshaft rod journal. Holoi ka puke pai lāʻau ma ke ʻano torsional i kekahi ʻano ma lalo o kēia ikaika. ʻO nā haʻalulu Harmonic ka hopena ma muli o ka neʻe ʻana o ka torsional i hāʻawi ʻia ma ka crankshaft. ʻO kēia mau harmonics kahi hana o nā mea he nui e pili ana i nā alapine i hana ʻia e ka puhi maoli a me nā alapine kūlohelohe i hana ʻia e nā metala ma lalo o ke koʻikoʻi o ka puhi ʻana a me ka flexing. I kekahi mau ʻenekini, hiki i ka neʻe ʻana o ka crankshaft i kekahi mau wikiwiki ke hoʻohui pū me nā haʻalulu harmonic, e hoʻoulu ai i ka resonance. I kekahi mau hihia, hiki i ka resonance ke hoʻoikaika i ka crankshaft a hiki i ka haki ʻana a i ʻole ka pau ʻole.
