1. Amakolero Background and Problem .

Namuziga z’omukono omugumu .bye bitundu ebikulu ebikola mu byuma by’amakolero, ebyuma eby’obujjanjabi, ebyuma by’emmere n’ennimiro endala, era okwesigika kwabyo kukosa butereevu obukuumi bw’emirimu gy’ebyuma. Mu myaka egiyise, olw’okulongoosa mu ngeri y’okukola ebintu mu ngeri ey’obwengula, akatale k’ensi yonna aka Solid Handwheel kagenda mu maaso n’okukula (okusuubirwa okutuuka ku ddoola za Amerika akawumbi kamu n’obukadde 23 mu 2024, nga buli mwaka okukula kwa 4.8%). Wabula, okumenya okwogera kubaawo emirundi mingi, ekivaamu ebyuma okuyimirira, ssente z’okuddaabiriza okulinnya, n’okutuuka ku bubenje obw’obukuumi. Ekiwandiiko kino kigatta okunoonyereza okw’ekikugu n’ebikwata ku katale okwekenneenya ennyo ebivaako okumenya n’okuteesa ku ndagiriro z’okulongoosa.

2. Okwekenenya ebikulu ebivaako okumenyawo okwogera .

Okuyita mu kunoonyereza ku mbeera n’okukebera mu laboratory, ebikulu ebivaako okumenya bisobola okufunzibwa mu biti bino wammanga bitaano:

2.1 Ebizibu by’ebintu (ebibalirirwamu 32%) .

Sulfide inclusions: The excessive sulfur content (>0.013%) mu kyuma ekitono-Kema ebyuma nga Q235PL kivaako okunyeenyezebwa kw’ensalo z’empeke n’okukendeeza ku kuziyiza obukoowu.

Okulongoosa ebbugumu mu ngeri etali ntuufu: Ensengekera y’ebyuma munda mu mboozi tekwatagana, era enjawulo mu kugabanya obukaluba esukka 15%.
Case: Oluvannyuma lw’ekkolero lya nnamuziga okukyusa Q235PL ne BG380CL, omuwendo gw’okumenya gwakka ebitundu 47%.

2.2 Ebizibu mu dizayini (ebibaliriddwa ku 25%) .

Obugumu obutakwatagana: Enjawulo y’obuwanvu wakati wa rim ne hub esukka 30%, era okunyogoza kusengekebwa.

Irrational spoke layout: The spoke crossing angle is too large (>60℃), era ensaasaanya ya situleesi wansi w’omugugu ogw’amaanyi (dynamic load) si ya bbalansi.

Data: Oluvannyuma lw’okulongoosa dizayini y’ekinnya kya spoke, obulamu bw’ekika ekimu eky’omuguwa gw’omu ngalo kyongeddwako okutuuka ku ssaawa ezisukka mu 8,000.

2.3 Ensonga z’enkola y’okukola (okubalirira 20%) .

2.4 Okukozesa obutonde n’okulabirira (15%) .

Okukulukuta: Mu mbeera ey’ebbugumu n’obunnyogovu, ekipande ky’ekyuma ekikuba mm 0.5 kisobola okuleeta enjatika z’obukoowu.

Overload: Omugugu ogukyukakyuka bwe gusukka omuwendo gwa dizayini emirundi 1.5, akabi k’okumenya kweyongera nnyo.

2.5 Okuteeka n’okuddaabiriza mu ngeri etali ntuufu (8%) .

Okuteeka mu ngeri enkyamu: Okulemererwa okunyweza obuuma mu ndagiriro ya diagonal kivaako okusika omuguwa okutali kwa bwenkanya.

Missing Maintenance: 80% ku bakozesa tebatera kukebera spoke preload.

3. Emisango egya bulijjo n’obuyambi bwa data .

3.1 Ebyuma ebikozesebwa mu by’obujjanjabi Akabenje k’okumenya omudumu gw’emikono .

Background: Ekyuma ekikuba ebyuma mu ddwaaliro CT kyayogera ku ssimu, ekyavuddeko okuggalawo mu bwangu.

Okwekenenya: Ekintu eky’okwogera kyali kya kyuma ekitali kizimbulukuse 304 ekitatuukana na mutindo, era enjatika z’okukulukuta kw’okunyigirizibwa (SCC) zaaliwo mu mbeera y’okukulukuta kw’amazzi ga chloride ion.

Okufiirwa: Okuddaabiriza ssente za Yuan 82,000, essaawa 48 ez’okuyimirira zaakosezza okwekebejja 300.

3.2 Okulemererwa kwa roboti ya roboti mu makolero .

Data: okulondoola robots 50 ez’omulembe gwe gumu zazudde nti:

Fracture rate: 18% ku midumu gya bulijjo egy’ekyuma ate 3% gyokka ku midumu egy’omu ngalo egy’omugatte.

Economic Efficiency: Okukozesa-Strength Aluminium Alloy Spokes, omuwendo gw’obulamu gukendeezebwako ebitundu 26%.

4. Ebigonjoolwa n’okuyiiya tekinologiya .

4.1 Ekkubo ly’okulongoosa ebintu .

4.2 Enteekateeka y’okulongoosa enkola .

Precision Casting: Tekinologiya wa Vacuum Degassing akozesebwa okufuga ebirimu okuyingiza wansi wa 0.005%.

Ennongoosereza mu ngeri ey’amagezi: Yingiza sensa ezisika okulondoola enkyukakyuka ezisooka okutikka mu kiseera ekituufu (ensobi .<±3%).

4.3 Ebiteeso ebikwata ku nteekateeka y’okukola dizayini .

Spoke Layout: Enkoona y’okusala efugibwa ku 30℃-45℃okukendeeza ku stress concentration.

Thickness gradient: Hub-Omugerageranyo gw’obuwanvu bwa RIM tegusukka 1:1.2, era ekitundu eky’enkyukakyuka kyettanira dizayini ya arc .

5. Enkosa y’akatale n’emitendera egy’omu maaso .

Enkyukakyuka mu nsengeka y’ebisale: Ekitundu ky’ebisale by’ebintu byeyongera okuva ku bitundu 45% okutuuka ku bitundu 60%, naye okukendeera kw’omuwendo gw’okulemererwa kwakendeeza ku nsaasaanya yonna.

Enkula y’okuvuganya: Elesa, NBK ne kkampuni endala ezikulembedde ziyanguwa okutegeka entegeka y’emidumu egy’omu ngalo egy’omugatte, era omugabo gw’akatale gusuubirwa okutuuka ku bitundu 38% mu 2024.

Policy Drive: Omutindo gwa EU EN 16740 gulimu obulamu bw’obukoowu obw’okwogera ng’ekiraga nti olina satifikeeti ekakatako.

6. Appendix: emmeeza y’okunoonyereza ku kunoonyereza ku makolero .

Mu bufunzi:

Ekizibu ky’ebisibo ebimenyese eby’emidumu egy’omu ngalo ebigumu byetaaga okulongoosebwa mu bitundu bina: ebikozesebwa, dizayini, enkola, n’okuddaabiriza. Olw’okutunda ebintu eby’amaanyi ebya waggulu-eby’amaanyi ne tekinologiya ow’amagezi ag’okulondoola, amakolero gajja kukyuka okutuuka ku kwesigika okw’amaanyi n’obulamu obuwanvu. Ebitongole byetaaga okwanguya okuddiŋŋana kwa tekinologiya okusobola okugumira omutindo gw’obukuumi bw’amakolero ogweyongera okukakali n’okuvuganya ku katale.
