Monga gawo lofunikira pakuyesa kwazinthu zamakina, kuyesa kwamphamvu kumagwira ntchito yofunika kwambiri pakupanga mafakitale, kafukufuku wazinthu ndi chitukuko, ndi zina zambiri. Kodi mwazindikira izi?

1.Sensor yamphamvu sikugwirizana ndi zomwe zimayesedwa:

Mphamvu yamagetsi ndi gawo lofunikira pakuyesa kolimba, ndipo kusankha mphamvu yoyenera ndikofunikira. Zolakwa zina zomwe zimachitika nthawi zambiri ndi izi: kusawerengera mphamvu ya mphamvu, kugwiritsa ntchito mphamvu yokhala ndi mitundu yosayenera, ndi kukalamba mphamvu yamphamvu kuti igonjetse.

Yankho:

Zinthu zotsatirazi ziyenera kuganiziridwa posankha chojambulira choyenera kwambiri malinga ndi chitsanzo:

1. Mphamvu ya sensa:
Dziwani kuchuluka kwa sensor yamphamvu yofunikira potengera kuchuluka kwamphamvu komanso kuchepera kwa zotsatira zomwe zimafunikira pa mayeso anu. Mwachitsanzo, kwa zitsanzo za pulasitiki, ngati mphamvu zamakokedwe zonse ndi modulus ziyenera kuyesedwa, m'pofunika kuganizira mozama za mphamvu za zotsatira ziwirizi kuti musankhe mphamvu yoyenera.

2. Kulondola ndi kulondola kwamitundu:

Miyezo yolondola yodziwika bwino ya masensa amphamvu ndi 0.5 ndi 1. Kutenga 0.5 mwachitsanzo, nthawi zambiri kumatanthauza kuti kulakwitsa kwakukulu komwe kumaloledwa ndi dongosolo la kuyeza kuli mkati mwa ± 0.5% ya mtengo wosonyezedwa, osati ± 0.5% ya mlingo wonse. Ndikofunika kusiyanitsa izi.

Mwachitsanzo, kwa mphamvu ya mphamvu ya 100N, poyesa mphamvu ya 1N, ± 0.5% ya mtengo wosonyezedwa ndi ± 0.005N cholakwika, pamene ± 0.5% ya sikelo yonse ndi ± 0.5N cholakwika.
Kukhala olondola sikutanthauza kuti mndandanda wonsewo ndi wolondola mofanana. Payenera kukhala malire otsika. Panthawiyi, zimatengera kulondola kwamtundu.
Kutengera machitidwe osiyanasiyana oyesera monga chitsanzo, masensa amphamvu a UP2001&UP-2003 amatha kukwaniritsa kulondola kwamlingo wa 0.5 kuyambira sikelo yonse mpaka 1/1000 ya sikelo yonse.

Chokhacho sichili choyenera kapena ntchitoyo ndi yolakwika:
Chojambulacho ndi sing'anga yomwe imagwirizanitsa mphamvu ya mphamvu ndi chitsanzo. Momwe mungasankhire chojambulacho chidzakhudza mwachindunji kulondola ndi kudalirika kwa kuyesa kolimba. Kuchokera pamawonekedwe oyesera, zovuta zazikulu zomwe zimachitika chifukwa chogwiritsa ntchito zosayenera kapena ntchito yolakwika ndikuterera kapena kusweka nsagwada.

Kutsetsereka:

Kutsetsereka kowonekera kwambiri kwachitsanzocho ndi chithunzi chomwe chikutuluka muzitsulo kapena kusinthasintha kwamphamvu kwa piritsi. Kuphatikiza apo, imathanso kuweruzidwa polemba chizindikiro pafupi ndi malo okhomerera mayeso asanayesedwe kuti awone ngati mzere wa chizindikiro uli kutali ndi malo okhomerera, kapena ngati pali chizindikiro chokoka pachimake cha dzino lachitsanzo cha clamping.

Yankho:

Pamene slippage imapezeka, choyamba tsimikizirani ngati cholembera chamanja chikumangika pamene mukugwedeza chitsanzo, ngati mpweya wa mpweya wa pneumatic clamp ndi waukulu mokwanira, komanso ngati kutalika kwa chitsanzo ndikokwanira.
Ngati palibe vuto ndi opareshoni, ganizirani ngati kusankha kwa nkhope ya clamp ndi koyenera. Mwachitsanzo, mbale zachitsulo ziyenera kuyesedwa ndi nkhope za serrated clamp m'malo mwa nkhope zosalala, ndipo mphira wokhala ndi zopindika zazikulu ayenera kugwiritsa ntchito zotsekera zodzitsekera kapena zopumira m'malo mogwiritsa ntchito zikhomo zamanja.

Kuthyola nsagwada:
Yankho:

Nsagwada zachitsanzo zimasweka, monga momwe dzinalo limatanthawuzira, kusweka pa clamping point. Mofanana ndi kutsetsereka, m'pofunika kutsimikizira ngati kukakamiza clamping pa chitsanzo ndi yaikulu kwambiri, kaya clamp kapena nsagwada pamwamba amasankhidwa moyenera, etc.
Mwachitsanzo, poyesa kuyesa kwa zingwe, kuthamanga kwambiri kwa mpweya kumapangitsa kuti chithunzicho chisweke pansagwada, zomwe zimapangitsa kuti pakhale mphamvu zochepa komanso kutalika; poyesa filimu, nsagwada zokhala ndi mphira kapena nsagwada za waya ziyenera kugwiritsidwa ntchito m'malo mwa nsagwada zopindika kuti zisawononge chithunzicho ndikupangitsa kuti filimuyo isachedwe.

3. Kuyika molakwika unyolo:

Kuyanjanitsa kwa unyolo wonyamula katundu kumatha kumveka bwino ngati mizere yapakati ya sensa yamphamvu, mawonekedwe, adapter ndi fanizo ili molunjika. Pakuyesa kwamphamvu, ngati kusanja kwa unyolo wolemetsa sikuli bwino, kuyesako kudzakhala ndi mphamvu yowonjezera yopotoka panthawi yotsitsa, zomwe zimapangitsa kuti pakhale mphamvu yosagwirizana komanso kukhudza kutsimikizika kwa zotsatira za mayeso.

Yankho:

Mayeso asanayambe, malo apakati a tcheni cha katundu kupatulapo chitsanzocho chiyenera kufufuzidwa ndi kusinthidwa. Nthawi iliyonse chitsanzocho chikatsekeredwa, tcherani khutu ku kusasinthasintha pakati pa malo a geometric a chitsanzo ndi nsonga yonyamula katundu. Mutha kusankha makulidwe otsekereza pafupi ndi kukula kwa clamping ya chitsanzocho, kapena kukhazikitsa chipangizo chapakati cha chitsanzo kuti muyike ndikuwongolera kubwerezabwereza.

4.Kusankha molakwika ndikugwiritsa ntchito magwero azovuta:

Zida zidzapunduka panthawi yoyeserera. Zolakwika zofala pakuyezetsa kwa zovuta (deformation) zimaphatikizapo kusankha kolakwika kwa gwero la kuyeza kwa zovuta, kusankha kosayenera kwa extensometer, kuyika molakwika kwa extensometer, kusanja kolakwika, ndi zina zambiri.

Yankho:

Kusankhidwa kwa gwero la zovuta kumatengera geometry ya chitsanzo, kuchuluka kwa mapindikidwe, ndi zotsatira zoyezetsa zofunika.
Mwachitsanzo, ngati mukufuna kuyeza ma modulus a mapulasitiki ndi zitsulo, kugwiritsa ntchito miyeso yosunthika kwa mitengo kumabweretsa zotsatira zotsika. Panthawi imeneyi, muyenera kuganizira kutalika kwa chitsanzo ndi sitiroko kuti musankhe extensometer yoyenera.

Kwa zingwe zazitali za zojambulazo, zingwe ndi zitsanzo zina, kusuntha kwa mtengo kungagwiritsidwe ntchito kuyeza kutalika kwawo. Kaya mukugwiritsa ntchito mtengo kapena chowonjezera, ndikofunikira kuwonetsetsa kuti chimango ndi extensometer zimayezedwa musanayambe kuyezetsa.

Nthawi yomweyo, onetsetsani kuti extensometer yayikidwa bwino. Siyenera kukhala yotayirira kwambiri, kupangitsa kuti extensometer itsetsereka panthawi yoyesa, kapena yolimba kwambiri, zomwe zimapangitsa kuti chithunzicho chisweke pa tsamba la extensometer.

5. Mafupipafupi a zitsanzo zosayenera:

Kuchuluka kwa zitsanzo za data nthawi zambiri kumanyalanyazidwa. Mafupipafupi ochepera a sampuli angayambitse kutayika kwa deta yofunikira komanso kukhudza zowona za zotsatira. Mwachitsanzo, ngati mphamvu yeniyeni yeniyeni siinasonkhanitsidwe, zotsatira zake zidzakhala zochepa. Ngati ma sampuli achuluka kwambiri, amakhala ochulukirapo, zomwe zimapangitsa kuti deta ikhale yochepa.

Yankho:

Sankhani zisankho zoyenera pafupipafupi kutengera zomwe zimayesedwa komanso katundu. Lamulo lalikulu ndikugwiritsa ntchito ma frequency a 50Hz sampling. Komabe, kuti zisinthe mwachangu, zisankho zapamwamba ziyenera kugwiritsidwa ntchito kujambula deta.

6. Zolakwika zoyezera miyeso:

Zolakwika zoyezera miyeso zimaphatikizapo kusayeza kukula kwachitsanzo, zolakwika za malo, zolakwika za zida zoyezera, ndi zolakwika zolowetsamo.

Yankho:

Poyesa, kukula kwachitsanzo choyenera sikuyenera kugwiritsidwa ntchito mwachindunji, koma muyeso weniweni uyenera kuchitidwa, apo ayi kupsinjika maganizo kungakhale kochepa kwambiri kapena kwakukulu.

Mitundu yosiyanasiyana ya zitsanzo ndi makulidwe amafunikira kukakamiza kosiyana koyesa komanso kulondola kwa chipangizo choyezera.

Chitsanzo nthawi zambiri chimafunika kuyeza kukula kwa malo angapo kuti chikhale pafupifupi kapena kutenga mtengo wocheperako. Samalirani kwambiri zojambulira, kuwerengera ndi kulowetsamo kuti mupewe zolakwika. Ndikoyenera kuti mugwiritse ntchito chipangizo choyezera miyeso chodziwikiratu, ndipo miyeso yoyezera imalowetsedwa mu pulogalamuyo ndikuwerengeredwa motengera kupewetsa zolakwika pakugwiritsira ntchito ndikuwongolera magwiridwe antchito a mayeso.

7. Vuto lokhazikitsa mapulogalamu:

Chifukwa chakuti hardware ili bwino sizikutanthauza kuti zotsatira zomaliza ndizolondola. Miyezo yoyenera yazinthu zosiyanasiyana idzakhala ndi matanthauzo enieni ndi malangizo oyesera pazotsatira za mayeso.

Zokonda mu pulogalamuyo ziyenera kutengera matanthauzo awa ndi malangizo oyesera, monga kutsitsa, kuyesa mayeso, kusankha mtundu wa mawerengedwe ndi zoikamo zapadera.

Kuphatikiza pa zolakwika zomwe zili pamwambazi zokhudzana ndi dongosolo loyesera, kukonzekera kwa zitsanzo, malo oyesera, ndi zina zotero zimakhalanso ndi zotsatira zofunikira pakuyesa kwamphamvu ndipo ziyenera kutsatiridwa.
