Kuinka laskea Pressure Vessel

Mikä on Pressure Vessel?

Pressure vessel stress depends on pressure, geometry, and material. Proper design prevents catastrophic failure; all vessels require rigorous analysis.

Kaava

Thin-walled hoop stress: σ = (P × r) / t
P
P value — Variable used in the calculation

Vaiheittainen opas

  1. 1Thin-walled hoop stress: σ = (P × r) / t
  2. 2Thin-walled longitudinal: σ = (P × r) / (2t)
  3. 3Thick-walled uses complex formulas; pressure determines stress

Ratkaistut esimerkit

Syöte
Cylinder r=200mm, t=10mm, P=5 MPa
Tulos
Hoop stress ≈ 100 MPa
Governs failure mode

Yleisiä virheitä vältettäväksi

  • Neglecting stress concentration at nozzles
  • Under-sizing vessel wall thickness

Usein kysytyt kysymykset

Why is hoop stress higher than longitudinal?

Hoop stress acts in two directions around vessel; only half the stress resists longitudinal loading.

How are vessel codes applied?

ASME Section VIII governs U.S. pressure vessel design; requires rigorous calculations and inspections.
