He kūpono no ka mīkini paʻi uila uila 1846481C92

Mechanical method

Hana ʻia ka mālama ʻana i ka mīkini paʻa i ka wā i hoʻokumu ʻia ai ka huahana ma hope o ka uku ʻana a me ka hoʻoponopono ʻana i ke kaapuni kelepona ukana a me ka sila pale.ʻO nā kaʻina hana nui ka pulse fatigue method, overload static pressure method and vibration aging method.

(1) Pulsating hana luhi

Hoʻokomo ʻia ke kelepona haʻahaʻa ma ka mīkini hoʻāʻo haʻahaʻa haʻahaʻa haʻahaʻa, a ʻo ka palena kiʻekiʻe i helu ʻia i ka ukana a i ʻole 120% helu ʻia, a ʻo ka pōʻai he 5,000-10,000 mau manawa ma ke alapine o 3-5 mau manawa i kekona.Hiki iā ia ke hoʻokuʻu maikaʻi i ke koena o ke koʻikoʻi o ka elastic element, resistance strain gauge a me ka strain adhesive layer, a maopopo loa ka hopena o ka hoʻomaikaʻi ʻana i ka helu ʻole a me ka paʻa o ka naʻau.

(2) ʻO ke kaʻina hana kaomi static overload

ʻO ka manaʻo, kūpono ia no nā ʻano ana like ʻole, akā i ka hana hana, hoʻohana nui ʻia ka alumini alloy liʻiliʻi.

Penei ke kaʻina hana: i loko o kahi mea hoʻouka kaumaha maʻamau maʻamau a i ʻole nā ​​mea hoʻouka uila mīkini maʻalahi, e hoʻopili i ka ukana helu 125% i ka cell load no nā hola 4-8, a i ʻole e hoʻopili i ka ukana helu 110% no 24 mau hola.Hiki i nā kaʻina hana ʻelua ke hoʻokō i ke kumu o ka hoʻokuʻu ʻana i ke koʻikoʻi koena a me ka hoʻomaikaʻi ʻana i ka zero point a me ka paʻa o ka naʻau.Ma muli o nā mea hana maʻalahi, ke kumukūʻai haʻahaʻa a me ka hopena maikaʻi, hoʻohana nui ʻia ke kaʻina hana static pressure overload e nā mea hana alumini alumini load cell.

(3) vibration elemakule ala

Hoʻokomo ʻia ke kelepona hoʻouka ma luna o ke kahua vibration me ka helu sinusoidal thrust e hālāwai ana i nā koi o ka ʻelemakule vibration, a ua manaʻo ʻia ke alapine e like me ka helu helu o ka cell kaupaona e hoʻoholo ai i ka haʻahaʻa vibration i noi ʻia, ka hana pinepine a me ka manawa haʻalulu.ʻOi aku ka maikaʻi o ka ʻelemakule resonance ma mua o ka ʻelemakule vibration i ka hoʻokuʻu ʻana i ke koʻikoʻi koena, akā pono ke ana ʻia ke alapine maoli o ka load cell.Hōʻike ʻia ka ʻelemakule vibration a me ka resonance e ka haʻahaʻa haʻahaʻa o ka ikehu, ka manawa pōkole, ka hopena maikaʻi, ʻaʻohe pōʻino i ka ʻili o nā mea elastic a me ka hana maʻalahi.ʻAʻole maopopo ke ʻano o ka ʻelemakule vibration.ʻO nā kumumanaʻo a me nā manaʻo i hoʻopuka ʻia e nā poʻe loea ʻē aʻe, ʻo ia ka: plastic deformation theory, fatigue theory, lattice dislocation slip theory, energy viewpoint and material mechanics viewpoint.
