Mphamvu yokoka ndi mphamvu yokoka yomwe imapangitsa chinthu kuzungulira. Mukatsegula chitseko kapena kupotoza sikurufu, mphamvu yomwe mumagwiritsa ntchito imachulukitsidwa ndi mtunda kuchokera pamalo ozungulira imapanga mphamvu yokoka.
Pa ma hinge, torque ikuyimira mphamvu yozungulira yomwe imapangidwa ndi chivindikiro kapena chitseko chifukwa cha mphamvu yokoka. Mwachidule: Chivindikiro chikakhala cholemera komanso pakati pake pa mphamvu yokoka pali kutali ndi hinge, mphamvuyo imakhala yayikulu.
Kumvetsetsa mphamvu ya magetsi kumakuthandizani kusankha hinge yoyenera kuti gululo lisagwedezeke, lisagwe mwadzidzidzi, kapena kumva lopepuka kwambiri mukatseka.
N’chifukwa Chiyani Tiyenera Kuwerengera Hinge Torque?
Ma hinge amagwiritsidwa ntchito kwambiri m'ma flip-lids ndi m'ma kabati. Zitsanzo zake ndi izi:
● Zotchingira laputopu - Chotchingiracho chiyenera kupereka mphamvu yokwanira kuti chiwongolero cha sikirini chikhale chofanana.
● Zivundikiro za bokosi la zida kapena makabati - Izi nthawi zambiri zimakhala zazikulu komanso zolemera, zomwe zimapangitsa kuti mphamvu ikhale yokwera.
● Zitseko za zida zamafakitale kapena zivindikiro za zida - Mapanelo olemera amafuna mahinji olimba mokwanira kuti asagwere mosafunikira.
Ngati mphamvu ya magetsi ili yotsika kwambiri, chivindikirocho chidzatsekedwa mwamphamvu.
Ngati mphamvu ya torque ili yokwera kwambiri, chivindikirocho chimakhala chovuta kutsegula kapena chimakhala cholimba.
Kuwerengera mphamvu ya hinge kumaonetsetsa kuti mphamvu ya hinge ndi yapamwamba kuposa mphamvu yopangidwa ndi chivindikiro, zomwe zimapangitsa kuti wogwiritsa ntchito azigwiritsa ntchito mosavuta komanso motetezeka.
Momwe Mungayesere Torque
Mfundo yaikulu ndi iyi: Mphamvu = Mphamvu × Kutalika.
Fomula yake ndi iyi:
T = F × d
Kumene:
T= mphamvu (N·m)
F= mphamvu (nthawi zambiri kulemera kwa chivindikiro), mu Newtons
d= mtunda kuchokera pa hinge kupita pakati pa chivindikiro cha mphamvu yokoka (mtunda wopingasa)
Kuwerengera mphamvu:
F = W × 9.8
(W = kulemera mu kg; 9.8 N/kg = kuthamanga kwa mphamvu yokoka)
Pa chivindikiro chogawanika mofanana, pakati pa mphamvu yokoka pamakhala pakati (L/2 kuchokera ku hinge).
Kuwerengera Chitsanzo
Utali wa chivindikiro L = 0.50 m
Kulemera W = 3 kg
Pakati pa mtunda wa mphamvu yokoka d = L/2 = 0.25 m
Gawo 1:
F = 3 kg × 9.8 N/kg = 29.4 N
Gawo 2:
T = 29.4 N × 0.25 m = 7.35 N·m
Izi zikutanthauza kuti makina olumikizira ayenera kupereka mphamvu ya 7.35 N·m kuti athane ndi kulemera kwa chivindikirocho.
Ngati mugwiritsa ntchito ma hinge awiri, hinge iliyonse imakhala ndi pafupifupi theka la mphamvu ya torque.
Mapeto
Kuti muyesere mphamvu ya hinge torque yofunikira:
● Mphamvu (T) = Mphamvu (F) × Mtunda (d)
● Mphamvu imachokera ku kulemera kwa chivindikirocho
● Mtunda umatsimikiziridwa ndi pakati pa mphamvu yokoka
● Ma hinge awiri amagawana mphamvu ya torque
● Nthawi zonse sankhani hinge yokhala ndi torque yokwera pang'ono kuposa mtengo wowerengedwa
Zomwe zili pamwambapa ndi mfundo zoyambira zokha. Mu ntchito zenizeni, zinthu zina ziyeneranso kuganiziridwa powerengera mphamvu ya hinge. Khalani omasuka kulumikizana nafe, ndipo tikhoza kuwunikanso polojekiti yanu mwatsatanetsatane pamodzi!
