Ubushakashatsi kuri Compressive Elastic Modulus Yipimisha Uburyo hamwe nubuhanga bwo Gukoresha Amashanyarazi ya Laminated

Muri umuhanda munini wububiko, reberi yamashanyarazi zikoreshwa cyane hagati yimiterere nuburinganire bwikiraro. Bafite uruhare runini muri kohereza imitwaro ihagaritse, kwakira imiterere yimiterere , na gutanga vibration kwigunga no kugabanuka.

Urebye muburyo bwa mehaniki, iyi miterere yuburyo irahuye cyane hasi yinyeganyeza, byoroshye reberi , na Subgrade yamashanyarazi , Bisanzwe ubwubatsi bwa rubber vibration ibicuruzwa . Sisitemu zose zishingiye kuri imyitwarire yo guhindura ibintu hamwe nubushobozi bwo gukwirakwiza ibikoresho bya reberi munsi uburyo bwo kwikuramo no gukata ibintu.

Mubisanzwe, gushimangira ibice bya reberi yamashanyarazi bigizwe na ibyuma byinshi byoroheje cyangwa ibyuma byicyuma . Munsi yimbogamizi zibi bishimangira, the reberi ihagarikwa neza, bityo igatezimbere cyane imbaraga zo kwikuramo na muri rusange gukomera ya reberi.

Igihe kimwe, mugihe byemeza hejuru ubushobozi bwo kwikorera umutwaro , birahagije ubushobozi bwo guhindura ibintu munsi ya horizontal yimurwa irashobora kugerwaho. Ibiranga birakomeye muburyo bwo gushushanya Subgrade yamashanyarazi na byoroshye reberi.

Uwiteka uburyo bwo gupima ibintu byoroshye ni bumwe mu buryo bwibanze bwo gusuzuma i imikorere ya mashini Bya reberi yamashanyarazi . Hamwe nogushira mubikorwa ibipimo bigezweho, byombi uburyo bwo kubara na uburyo bwo kwipimisha Byahindutse.

Binyuze mubushakashatsi bwubushakashatsi, ubu bushakashatsi burasesengura buri gihe ibintu by'ingenzi bigira ingaruka ku kizamini n'urwego rwabo rwo kugira uruhare, rutanga gihamye ishingiro rya tekiniki yo kubaka ikiraro no kugenzura ibishushanyo mbonera.

1. Incamake yuburyo bwo Kwipimisha Elastic Modulus Uburyo bwo Kwipimisha

1.1

Mu 1981, Lindley PB yatanze icyerekezo cyerekana kubara i guhagarikwa gukomeye kwa reberi , bishingiye ku gitekerezo cya imyitwarire idahwitse yimyitwarire yibikoresho bya reberi . Kuva ubu iyi nyigisho yakoreshejwe cyane mubikorwa byubuhanga.

Munsi vertical compressive imizigo ibikoresho bya reberi ntibigaragaza gusa umubyimba-icyerekezo cyo kwikuramo ibintu , ariko kandi urwego runaka rwa guhindagurika kuruhande . Iyi myitwarire yubukorikori nayo irakoreshwa kuri hasi yinyeganyeza na byoroshye reberi in kubaka sisitemu yo kugenzura ibinyeganyega.

1.2 Kubara

Kuri reberi irimo reberi , tuvuge ko ibikoresho bya reberi bidashoboka kandi bikorerwa kwikuramo neza , i guhagarikwa ni Kubara Nka:

Kv = E1⋅A0n⋅t1K_v = \ frac {E_1 \ cdot A_0} {n \ cdot t_1} Kv = n⋅t1E1⋅A0

Aho:

E₁ — Longitudinal elastique modulus ya rubber

A₀ — Agace keza ko kwikorera imitwaro

t₁ — Ubunini bwurwego rumwe

Iyi formula ifite agaciro gakomeye kuri reberi yamashanyarazi, Subgrade yamashanyarazi , na vibration kwigunga reberi ikoreshwa muri sisitemu yo gutambutsa gari ya moshi.

2. Igishushanyo mbonera cya Automatic Compressive Elastic Modulus Ikizamini

Uwiteka sisitemu yo kwipimisha elastike modulus yo kugerageza ahanini bigizwe na:

Imashini igerageza

Gusimburwa nimbaraga za sensor

Ikizamini cyumwuga hamwe na software isesengura amakuru

Mugihe cyo kugerageza, sisitemu irashobora ubudahwema kubona umutwaro uhagaze hamwe na compression deformasiyo yamakuru , mu buryo bwikora guhangayika , no kubara i compressive elastike modulus hamwe na gusesengura gutandukana.

Ikoreshwa rya sisitemu:

Igabanya cyane ibikorwa byintoki

Irinde neza amakosa yo gusoma yabantu

Komeza amakosa yo kugerageza mumipaka yemewe

Ubu buryo bwo kugerageza ntabwo bukoreshwa kuri gusa reberi yamashanyarazi , ariko na hasi yinyeganyeza na byoroshye reberi yo gusuzuma imikorere yubukanishi.

3. Kwiga Ikibazo Cyubwubatsi Kugereranya Uburyo bwo Kwipimisha

3.1 Ibisobanuro

A reberi Byahiswemo nkikigereranyo cyikigereranyo hamwe nibipimo bikurikira:

Diameter: Mm 140

Uburebure bwuzuye: 25 mm

Ubunini bwa rubber: 4 mm

Ubunini bw'icyuma: Mm 2

Umubare wibyuma bya plaque: Ibice 3

Agace keza ko kwikorera imitwaro: 15,366 mm²

Imiterere: 7.0

Ubunini bwa rubber: Mm 20

Ukurikije ibipimo bishya ,. igishushanyo mbonera cya compressive elastique modulus ni (303 ± 60) MPa.

3.2 Ingaruka zuburyo butandukanye bwo gupakira kubisubizo byikizamini

Gukora iperereza ku ngaruka za uburyo bwo gupakira , gahunda ebyiri zo gupakira zarateguwe:

Gahunda ya 1 (Ntabwo ari ibintu bisanzwe):

Igipimo gisanzwe cyo gupakurura no gupakurura

Inzinguzingo 3

Gahunda ya 2 (Gupakira bisanzwe):

Kwikuramo intambwe ukurikije amahame mashya

Urwego rwumutwaro rwagumishijwe kuri Amasegonda 120 mbere yo gushaka amakuru

Ibisubizo by'ibizamini byerekana ko:

Gahunda 1 Kugaragaza gutandukana birenze 3%, hamwe bigaragara ingaruka za hystereze

Gahunda ya 2 yerekana gutandukana munsi 3%, gutanga ibisubizo bihamye kandi byizewe

Uyu mwanzuro kandi ukora nkingirakamaro mugusuzuma imikorere miremire ya Subgrade yamashanyarazi munsi y'imizigo irambye.

4. Gupima Isesengura ridashidikanywaho mugihe cyo Kwipimisha

4.1 Ibintu bidashidikanywaho bitigenga kubintu bifatika

Muri byo harimo:

Ibipimo byo gupima ibikoresho byo gupima (imashini yo guhunika, metero zo kwimura, kwagura, n'ibindi)

Amategeko yo gukusanya amakuru

Itandukaniro mubisobanuro bisanzwe no gusoma nabakoresha

Uku gushidikanya kurashobora kugabanuka neza binyuze kwipimisha inshuro nyinshi na uburyo busanzwe bwo gukora.

4.2 Ibintu bidashidikanywaho bifitanye isano nikigereranyo

Harimo:

Amakosa muri ahantu heza ho kwikorera imitwaro

Amakosa yo gupimwa muri ubunini bwa reberi hamwe nuburebure bwicyuma

Amakosa muri gupima uburebure

Ingaruka za ubushyuhe bwibidukikije nubushuhe

Ibintu nkibi birakomeye mugupima kwa byoroshye reberi na hasi yinyeganyeza.

5. Kugenzura Ibipimo Byuzuye Muri rusange

Nyuma yamakosa yose yibipimo byahujwe, a igipimo cyuzuye ni. Ibipimo bifatika byerekana neza ntarengwa byemewe amakosa Kuri Ibyingenzi Ibyingenzi Nka umutwaro no kwimurwa.

Mugukurikiza byimazeyo ibipimo no kugenzura neza amakosa yibyiciro ,. kwizerwa no kumenya neza ibisubizo by'ibizamini birashobora kunozwa cyane.

Umwanzuro

Rubber yamashanyarazi ni ingenzi muri inyubako yikiraro , hamwe na bo imikorere yo kwikuramo bigira ingaruka umutekano wikiraro.

Binyuze mu buhanga bwo gukoresha uburyo bwo gupima ibintu byoroshye , hamwe na gupima isesengura ridashidikanywaho , kwibumbira hamwe birashobora kugenzurwa neza, bikagerageza neza.

Ibyavuye muri ubu bushakashatsi ntibireba gusa ikiraro , ariko kandi utange agaciro ibyerekezo kandi bifatika Kuri gushushanya, kugerageza, no gusaba Bya hasi yinyeganyeza, byoroshye reberi , na Subgrade yamashanyarazi , kimwe n'ibindi ubwubatsi bwa rubber vibration ibicuruzwa.

Muri umuhanda munini wububiko, reberi yamashanyarazi zikoreshwa cyane hagati yimiterere nuburinganire bwikiraro.
