Ibyerekeranye nicyapa kitagira umuyonga: ubu turi gake cyane icyuma cyumwimerere, ariko kubera ubwinshi bwacyo, igiciro cyinshi, ingorane zo gutoragura, ntibyoroshye gutwara nizindi mpamvu, isoko ikunze kugaragara cyane kumuzingo wibyuma bitagira umuyonga. .

Isahani isanzwe ikoreshwa mubyuma bigabanijwemo ibyiciro bibiri:

Ibyuma byerekana ibyuma byerekana ubugari

1, icyuma gikonjesha icyuma cya plaque plaque plaque plaque plaque.
A, isahani yicyuma igabanijemo mo m 1, 1,219 m hejuru yubuso, hejuru ya 1.5 m.
B. Ingano isanzwe yibyuma bidafite ingese ni m 1 * m 2, m 1,219 m * 2,438 m

2, isahani ishyushye isahani yicyuma igabanijwemo isahani ya coil, isahani iringaniye hamwe nisahani ishyushye.
A, isahani yicyuma isahani isanzwe ikoreshwa ni metero 1.5, metero 1.25
B, isahani yicyuma isahani ifite ubunini busanzwe 1.5 * 6 m, 1.8 * 6 m, 1,25 * 6 m.

Bikunze gukoreshwa ibyuma bidafite ibyuma

Inzira yo kubara yuburyo bwa plaque idafite ibyuma:

Uburemere bwa Theoretical (kg) = Uburebure (m) * Ubugari (m) * Ubunini (mm) * Uburemere bwihariye (ubucucike)

Igiciro cya plaque: igiciro coil * ubunini nyabwo / uburebure bwa theoretical + amafaranga yuzuye

Urugero rwibipimo byibisahani:

Umubyimba nyawo wubugari busanzwe bwa mm 2 isahani idafite ibyuma ni 1.8 mm, bityo uburemere bwa theoretical ya toni 2 yibyuma bitagira umuyonga ni toni 1.8.Niba igiciro cyo guhindura ari 11400 yuan / toni, igiciro cyo gupima ni hafi (2 / 1.80) * 11400 = 12650 yuan / toni, (kwihanganira uburemere bubi (1.80-2) / 2 * 100% = 10%, 11400 / (1 -9%) = 12650 yuan / toni) igiciro rusange kirapima, igiciro kiri hejuru;Igiciro cyinama cyahinduwe, kuruta uburemere bwa pound, igiciro kiri munsi yigiciro cya pound..

Ubukonje busanzwe buzunguruka butagira icyuma

Ubusanzwe bikoreshwa bishyushye bizengurutse ibyuma bya plaque

Ubwoko bwo kubara ibyuma

1, ikiguzi = umubyimba nyawo ÷ umubyimba * mugiciro + imizigo + amafaranga yo gutunganya

2, igiciro cya plaque ihinduranya igiciro cyibiciro = igiciro cyubunini * ubunini bukomeye / umubyimba + amafaranga meza 100

3, isahani yibiciro ihinduranya igiciro cya plaque = igiciro cyibibaho * uburebure bwubuyobozi / umubyimba ukomeye - amafaranga 100

4. Uburebure bwa reel = net reel uburemere /7.93/ ubugari bwa reel / ubunini nyabwo

5, algorithm yigiciro hamwe numusoro = uburemere bwibicuruzwa /1.04(1.04 byerekana amanota 4 -1.07 bisobanura amanota 7) urugero: toni 10000 yibicuruzwa /1.04=9615.3846 toni * toni igiciro = ibisubizo urugero: toni 1 yibicuruzwa = 15800 toni /1.04=15192.3077 igiciro nta musoro

6. Urebye uburemere bwibiciro nigiciro, shakisha uburemere bwuzuye bwubunini = uburemere * * igiciro

7, uburebure bwa plaque idafite uburebure χ ubugari χ burebure χ 7.93 nka 2.0 χ 1.22 χ 2.44 χ 7.93 = 47.2kg / igice

8, Umuyoboro wicyuma (OD - uburebure bwurukuta) χ 0.02491 nka (57-3.5) χ 3.5 χ 0.02491 = 4.66kg / m

9, ibyuma bitagira umuyonga ibyuma bya diameter χ diameter 0.00623 nka 18 χ 18 χ 0.00623 = 2.02kg / m

10, ibyuma bitagira umuyonga Inguni yumurongo Χ uruhande Χ Χ Χ nka 40 Χ 40 Χ 7.8 0.000198 7.8 0.000198 = 2,47 kg / m z'ubugari) 1.83 kg / m 3

11, ibyuma bitagira umuyonga uburebure bwa χ ubugari 0.00793 nka 8 χ 80 χ 0.00793 = 5.08kg / m
