0 Intshayelelo Ukusilela kwebhetri kuyingozi enkulu yokhuseleko kwinkqubo yonikezelo lwamandla elalela, indlela yokuthintela ukugqabhuka kwebhetri ingumcelimngeni kubuchwepheshe bokugcina ibhetri. Okwangoku, ukungaqiniseki kokusilela kokugqabhuka kwebhetri kube yeyona nto iqhuba iteknoloji yesilumkiso sebhetri yophando. Isitshixo ekufezekiseni ukusilela kwebhetri kukufumana eyona parameters isilumkiso.

Ngokucacileyo, ezona parameters zilumkiso zibalaseleyo kufuneka zibe nezi mpawu zintathu zilandelayo, oko kukuthi, ezinxulumene kakhulu nokusilela kwebhetri, umlinganiselo ophinda-phindayo, onokuthelekiseka. Ithiyori yokuguga kwebhetri kukukhokela uyilo lwebhetri, ukuvelisa kunye nokuphucula isiseko sethiyori, kodwa into yophando yethiyori yokuguga ibalulekile ekusebenzeni kwebhetri iyonke, kwaye ukusilela kwebhetri kubalulekile ngokusekelwe kumahluko ebhetri. Ke ngoko, ithiyori yokuguga kwebhetri ayisebenzi kwizitayile zebhetri Uhlalutyo kunye nophando lokusilela, oku kubhengezwa kokuqaqambisa umbono weendlela ezahlukeneyo zokulumkisa ngempazamo yebhetri.

Iindlela zobunjineli ezikhoyo, nokuba yindlela yamandla ombane we-monomer okanye isekethe yangoku + indlela yombane we-monomer, okanye indlela enkulu yokukhupha yangoku okanye indlela yokuvavanya umthamo okhawulezayo, akukho nto ithetha ukuba nomthamo webhetri njengeeparamitha zesilumkiso kwangethuba, kodwa eneneni Umthamo webhetri awuphindi ngokuthe ngqo umlinganiselo (njengovavanyo lokukhupha umthamo oqhelekileyo), kwaye awunawo umlinganiselo ongathanga ngqo ophindaphindayo (njengokunganyangeki komthamo wangaphakathi okanye ubungakanani bomthamo wangaphakathi). Ukuze ulahle ithiyori yokuguga kwebhetri, iimbono zokulumkisa ibhetri zifuneka ngokukhawuleza ukuphinda uhlolisise iindlela zokukhusela ibhetri ukusuka kumbono omtsha, ukwenzela ukuseka isiseko sethiyori sokufumana iiparitha ezilumkiso ezifanelekileyo, le yingxaki ekufuneka isonjululwe ngethiyori yokulimala kwebhetri. 1 Indlela yokwenzakala kwebhetri 1.

1 Umonakalo webhetri Intsingiselo Ukutolikwa kwezilumkiso eziqhelekileyo ukuba zibe yingozi kwiibhetri, zinokuthi ziqhubele phambili zenzululwazi njengoko: i-overcharged okanye i-overprints iya kubangela ukuphendulwa kwe-electrochemical engenakuguqulwa ngaphandle kwempendulo yokugcina amandla, olu yilo Ukusabela okungenakuguqulwa kuya konakalisa isakhiwo sokuqala kunye nokugcinwa kwamandla ebhetri. Oku kunokubekwa kumonakalo webhetri: umonakalo ozaliswe ngokugqithisileyo kumonakalo kwisakhiwo sebhetri kunye nomthamo wokugcina amandla. Phezulu, le ntsingiselo ayahlukanga kakhulu kwithiyori yokuguga kwebhetri kunye nokusetyenziswa kwebhetri ingqiqo.

Nangona kunjalo, le ntsingiselo iya kukhokelela ngokwendalo kwimiba emibini enentsingiselo yokwenene: 1) Inkqubo esemgangathweni esele ikhona kubunjineli obusebenzayo iya kuthintela ukonakala kwebhetri? 2) Emva kokuba kwenzeke umonakalo webhetri, luhlobo luni lomlinganiselo ophindaphindiweyo osele ebhetri, unokuthelekisa utshintsho lobungakanani bomzimba? 1.2 Isixokelelwano esisemgangathweni esikhoyo esilungileyo Intsingiselo yokungaphumeleli kwebhetri kunokuvela kwiimpazamo ezenziweyo, okanye isenokuvela kukungasebenzi kwesixhobo, ezi zizathu ayizozinto zophando kukwenzakala kwebhetri, kwaye ithiyori yokonakala kwebhetri ixhalabele ngakumbi malunga nokungathintelwa kokungaphumeleli kwebhetri. Ukuze ungabandakanyi zonke iintlobo zezinto ezingahlawulisiyo, kufuneka uqale uthethe inkqubo esemgangathweni ekhoyo.

Inkqubo esemgangathweni ekhoyo ekhoyo kufuneka ibandakanye: isixhobo samandla sokwenene esifanelekileyo ngokupheleleyo, iseti yeepakethi zebhetri yokwenene ezifanelekile ngokupheleleyo yi-monomer kwaye ziqhagamshelwe ngokweenkqubo, kwaye zibe nabasebenzi abaqeqeshiweyo bolawulo kunye nokugcinwa okuqhuba iinkqubo zokugcinwa okungqongqo, ngokufutshane, oku kufuneka kube yinto engafanelekanga, kodwa yinkqubo esemgangathweni ngokwenene. Ke, ngaba kukho ukonakala kwebhetri kwindlela elungileyo ekhoyo ekhoyo? 1.3 Ugqithiso lwemonomer yasekuhlaleni (i-monomeric microjjjjjjjjjjjjjjjjjjjjjjjjjjjj) 1) Iparamitha yeqela lebhetri 100 segment 2V, umthamo wegama 100A·H, apho i-1 umthamo wangempela ngu-97A·H, intsalela ye-99 yamandla okwenene yi-100A·H; 2) Iiparamitha zesixhobo sonikezelo lwamandla ombane oqhelekileyo ovaliweyo wendlela yokulawula iluphu, zonke ezo zihlawuliswe ngokupheleleyo ukuguqulwa kwesethi yombane = 240.

I-00V (impazamo yokwenza = 0, i-monomer = 2.400V), i-tetan yokupheliswa kokukhutshwa = 170.00V (impazamo yokubulawa) = 0, i-monomer = 1.

700V). Xa inkqubo iqhutywa phakathi kwayo yonke intlawulo kunye nokukhutshwa, ngokuqinisekileyo iya kubonakala amaxesha amabini akhethekileyo, oko kukuthi (1) iya kubonakala kwixesha lokuqala elikhethekileyo, kwaye ixesha lokuqala liyi-97A.·Amandla ombane ebhetri yeseli yeH> 2.

I-400V, kunye ne-voltage iyonke i-240.00V (ngeli xesha, ukunikezelwa kwamandla kuya kuqhubeka ukuhlawula), ixesha lokugqibela liyi-voltage epheleleyo = 240.00V (ngalo xesha, isixhobo sombane senza ngokuthe ngqo ukutshintshwa komlilo ogcweleyo).

Ngokuxhomekeke kwiintsingiselo zomonakalo webhetri, i-97A·Iibhetri ze-H zisebenza kwixesha elikhethekileyo, ngelixa ezinye i-99th 100A·Ibhetri ye-H iyasebenza ngaphakathi koluhlu lokhuseleko. (2) Ixesha lesibini lexesha elikhethekileyo liya kubonakala phantsi komsebenzi wokukhutshwa, kwaye ixesha lokuqala liyi-97A·Amandla ombane ebhetri e-H yi-1.700V, kwaye amandla ombane ewonke yi> 170.

I-00V (ngeli xesha, ukunikezelwa kwamandla kuya kuqhubeka nokukhupha), ixesha lokuphela kwexesha lilonke i-voltage = 170.00V (eli xesha ibhetri yepakethi iphelile). Ngeli xesha likhethekileyo icandelo 97A·Ibhetri ye-H iqhuba ngaphezulu kwemeko engaphezulu, iintsalela ezingama-99 amacandelo 100A·Ibhetri ye-H isasebenza ngaphakathi koluhlu lokhuseleko.

Ubukho benjongo yala maxesha amabini akhethekileyo, oko kukuthi, (1) Umahluko phakathi kwenkqubo yokwenyani kunye nalo mzekelo awukho ngaphezu kobukhulu bomthamo, kwaye ubungakanani bomthamo butshintsha kuphela ubude bexesha elikhethekileyo, akuchaphazeli Ubukho bexesha elikhethekileyo; lo mzekelo ubonisa ukuba ipakethi yebhetri inobungozi obungaphakathi bokhuseleko, ebonisa ukuba kukho uqhagamshelo lwangaphakathi olungenakuthintelwa phakathi komonakalo webhetri kunye nokugqabhuka kwebhetri. (2) Izixhobo ezilungileyo, ulawulo oluchanekileyo aluthinteli ukwenzeka komonakalo webhetri, kodwa le bhetri yomntu ezaliswe ngokugqithiseleyo igutyungelwe phantsi komsebenzi okhuselekileyo opheleleyo, ngokomlinganiselo, umlinganiselo womonakalo kuphela 1%, ixesha lokulimala Ngaphantsi kwe-3%. (3) Kakade ke, umlinganiselo we-1% womonakalo, okanye i-3% ixesha lomonakalo alanelanga ukusongela ukhuseleko lwenkqubo yonikezelo lwamandla elalela yonke, ukwenzela ukubala ukwenzakala kwe-micro-umonakalo, kodwa okoko nje kuphinda kuphindwe ekusebenzeni kwenkqubo yonikezelo lwamandla olugciniweyo Olu hlobo lwenkqubo yomonakalo ococekileyo iya kuphindwa.

Ngamanye amazwi, inkqubo yemicrosurizing eneneni ikhukulisekile ukuya kwinkqubo epheleleyo yenkqubo yonikezelo lwamandla egcinayo. (4) Umonakalo owahlukileyo kwiiparamitha zebhetri, iziphumo zokulimala kwe-microwas eziphambili ngumonakalo kunye nokugcinwa kwamandla ebhetri, okuya kwandisa ngakumbi umahluko we-monomer phakathi kwebhetri. Esi siphumo siye saba lixesha elizayo.

Unobangela micro-ukulimala, kucacile ukuba kukho isangqa esikhohlakeleyo sobudlelwane causal mutual, ngaloo ndlela akunakwenzeka ukubuza: iziphumo umonakalo ibhetri kuqhubeka nzulu ngexesha lesibini micro-ilahleko, de ibhetri ayisebenzi ngokupheleleyo, ukuqhubeka inkqubo yokungaphumeleli kunokuqhuba Iimeko, kodwa kufuneka ikhawuleziswe emva kokulimala ezininzi ukuze ziwohloke isiphumo esingenakuthintelwa. 1.4 I-Mechanical Fracture Model Case Ukuthelekiswa kokuqonda komfanekiso weepakethi zebhetri ezikwintsimi yombane, umatshini wokungaphumeleli ngokukhawuleza ubangelwa ngumatshini wokungaphumeleli ngokukhawuleza, kwaye imodeli yokuphuka kwentsimi yomatshini ingasetyenziselwa ukwenza umlinganiselo weklasi elula: ipakethi yebhetri, i-spring steel sheet kunye ne-mechanics.

(Intlakohlaza yamagqabi); umahluko kwiiparamitha zeqela ngalinye lebhetri, elifanayo, ukungalingani kwecandelo leqabunga;.
