1. Kuongororwa kwechimiro chechimiro cheiyo yakakosha formula
Mutemo Wekuchengetedza Misa
Ese mafomula anoenderana nechimiro chemuviri m=ρ×V (misa = density × vhoriyamu)
Density value
Theoretical density yearuminiyamu yakachena: 2,698 kg/m³ (20 ℃)
Iko kukosha kwe2,700 kg/m³ kunonzwisisika pakuverenga kwemaindasitiri (kukanganisa <0.1%).
2. Kuongororwa kweKusimba kweGeometric Formulas
2.1. Standard geometric volume formula
Square tube formula kurambidzwa:
Izvi ndezvechokwadi kana chubhu madziro ukobvu hwakafanana uye kona yemukati ikona yekona (iyo chaiyo square chubhu ine yakatenderedzwa shanduko, uye chikanganiso chedzidziso chinenge 1-3%).
3. Unit System Consistency Verification
Cross-unit calculation risk point research
4. Injiniya Yakakodzera Kugadziriswa
4.1. Muripo wezvinhu zvisina kunaka
4.2. Quantification of tolerance impact
Hukobvu kushivirira ± 10% → Kutsauka uremu ±(8% ~ 12%) (zvikamu zvakatetepa-zvakakomberedzwa zvakanyanya kunzwa)
Solution: W chaiyo = W theoretical × (1 + Δt / t) (Δt: kutsauka kweukobvu)
5. Bundary Condition Test
Kuongororwa kwakanyanya
Density anomaly scenario
7xxx alloy (7075): Measured density 2.810 g/cm³ → Kana 2.7g/cm³ ikashandiswa nekukanganisa, kukanganisa ndiko +4.1%.
Formula table
4t(A + B)- 4t² iverengero yeinjiniya kuverenga iyo inoverengerwa nekuwanza perimeter yechikamu nekukora kwemadziro uyezve nekubvisa makona mana.
Kuverengera muenzaniso:
1.6061 aluminium ndiro(1000 × 500 × 10 mm, kureba 2 m): W = 1000 × 500 × 2 × 0.0027 = 27 kg
2.7075 denderedzwa chubhu(kunze dhayamita 50 mm, kukobvu kwemadziro 3 mm, kureba 1.5 m): W = [(50-3)×3×3.1416×1.5]×0.00283 ≈ 5.65 kg
3. Square chubhu(40×40×2mm, kureba 3m): W = [2×2×(40+40-4)×3]×0.0027×0.98 ≈ 2.42 kg
Yakakurudzirwa Workflow
1. Sarudza density → 2. Yema saizi chaiyo → 3. Sarudza compensation factor → 4. Verenga neformula
