1. Xaqiijinta mabda'a jireed ee caanaha asaasiga ah
Sharciga Ilaalinta Mass
Dhammaan qaacidooyinka waxay ku saleysan yihiin dabeecadda jireed ee m=ρ×V (cuf = cufnaanta × mugga)
Qiimaha cufnaanta
Cufnaanta aragtida aluminium saafi ah: 2,698 kg/m³ (20℃)
Qiyaasta qiimaha 2,700 kg/m³ waa macquul xisaabinta warshadaha (khalad <0.1%)
2. Xaqiijinta Adagnimada Foomamka Joomatari
2.1. Qaaciddada mugga joomatari ee caadiga ah
Xayiraadaha qaaciddada tube square:
Tani waa run marka dhumucda gidaarka tuubbadu ay lebbis tahay oo xagasha guduhu ay tahay xagal toosan (tuubada labajibbaaran ee dhabta ah waxay leedahay wareejin wareegsan, qaladka aragtiduna waa qiyaastii 1-3%).
3. Xaqiijinta Joogteynta Nidaamka Cutubka
Baaritaanka dhibicda halista xisaabinta-cutubyada
4. Wax ka Beddelka Ku-habboonaanta Injineerinka
4.1. Magdhawga arrimo aan habboonayn
4.2. Tirada saamaynta dulqaadka
Dulqaadashada dhumucda ± 10% → leexashada miisaanka ± (8% ~ 12%) (Qaybaha dhuuban ayaa aad xasaasi u ah)
Xalka: W dhabta ah = W aragti × (1 + Δt / t) ( Δt: leexashada dhumucda)
5. Imtixaanka Xaalada Xuduudka
Xaqiijinta kiis aad u daran:
Cufnaanta xaalad aan caadi ahayn
7xxx Alloy (7075): Cufnaanta la qiyaasay 2.810 g/cm³ → Haddii 2.7g/cm³ si qalad ah loo isticmaalo, khaladku waa +4.1%.
Miiska caanaha
4t(A + B)- 4t² waa xisaabinta injineerinka caadiga ah kaas oo lagu dhufto wareegtada qaybta dhumucda gidaarka ka dibna laga jarayo afarta gees.
Tusaalaha xisaabinta:
1.6061 saxan aluminium(1000 × 500 × 10 mm, dhererka 2 m): W = 1000 × 500 × 2 × 0.0027 = 27 kg
2.7075 tube wareegsan(dhexroorka dibadda 50 mm, dhumucda gidaarka 3 mm, dhererka 1.5 m): W = [(50-3)×3×3.1416×1.5]×0.00283 ≈ 5.65 kg
3. Tuubbada labajibbaaran(40×40×2mm, dhererka 3m): W = [2×2×(40+40-4)×3]×0.0027×0.98 ≈ 2.42 kg
Socodka Shaqada ee lagu taliyay
1. Dooro cufnaanta → 2. Cabbir cabbirka dhabta ah → 3. Dooro qodobka magdhowga → 4. Ku xisaabi qaacido
