Uburyo FRP izamura inkingi igana ahirengeye

Fizika inyuma yibikorwa bya pole vault ikubiyemo guhuza imbaraga zingufu zabakinnyi hamwe na pole recoil. Mugihe usimbuka amanuka kumuhanda kumuvuduko ntarengwa, batera inkingi yoroheje mumasanduku, berekeza umuvuduko utambitse hejuru nkuko inkingi yunamye. Kugena igihe "gukuramo" neza birakomeye - kare cyane, kandi inkingi ntizatanga lift ihagije; bitinze cyane, kandi bibitswe ingufu za elastique ziratandukana aho kwerekana umukinnyi mwijuru.

Mugihe injeniyeri yihatira guca inzitizi zimikorere, zinjira cyane mubintu bitagereranywa nko gukomera kwa pole, igihe cyo kwisubiraho, no kugaruka kwingufu. Imikoranire hagati yubuhanga bwumukinnyi nibikoresho byabo birerekana ikibazo cyubwubatsi. Ubushakashatsi nubushakashatsi bwimbitse bujya muburyo bwo gusimbuka hejuru kugirango wohereze ingufu neza bishoboka.

Ba injeniyeri bihatira gushakisha uburinganire bwiza bwimbaraga, guhinduka, kuramba, nubucyo kubikoresho bya pole. Fiberglass ikomeza plastike (FRP) numukandida mwiza, wujuje ibi bisabwa neza. Iyi compte ikomatanya fibre yibirahure kugirango ikomere kandi ikomere hamwe na materique ya plastike ya polymer, bizana guhinduka. Igisubizo nikintu gikomeye ariko cyoroshye kugirango cyeze neza.

FRP itanga imbaraga zingana-kurenza ibipimo byibikoresho byabanje nkibiti, imigano, hamwe na fiberglass kare. Ibirahuri bya macrostructure bitanga imbaraga, mugihe materique ya polymer ya plastike iringaniza imbaraga zipakurura hejuru yazo. FRP irashobora kunama no kurambura kugirango ibike ingufu zidasanzwe mbere yo kwisubiraho vuba bihagije kugirango imbaraga nyinshi zigaruke.

Kuramba ni akandi karusho-inkingi ya FRP ikomeza imikorere ihamye ibihumbi byunamye. Bakomeza kugumana imiterere ihindagurika hamwe no gukomera byashizweho nabakinnyi runaka mumyaka myinshi yimyitozo namarushanwa. Gukomeza kunonosorwa birimo ibyuma bya pulasitiki bigezweho hamwe na fibre yerekanwe neza.

Ubushobozi burahari kuri FRP kugirango itange inkingi hamwe nimbaraga zitigeze zibaho zihuza imbaraga, elastique, imbaraga, nuburemere. Iyi mpirimbanyi irashobora gutanga umutekano wumutekano injeniyeri yifuza hamwe nuburyo bwihariye bwo gusubiza butuma abamotari bakomeye bazamuka cyane. Iterambere mubumenyi bwibintu hamwe na nano-injeniyeri ya matrike isumba iyindi itanga ejo hazaza heza kuri plastike ikomezwa na fiberglass ikozwe mubibuga bya pole vault.
