Example calculation

Calculation of eyelets

(in accordance with DIN 28086, November 1977)

Input data

  Eyelet head radius r1   mm (see Attachment 1)
  Hole center height h   mm
  Hole diameter d   mm
  Eyelet thickness s1   mm
  Eyelet connection weld thickness a1   mm
  Shackle bolt diameter ds   mm
  Reinforcing ring thickness sR   mm (two rings welded at both sides)
  Reinforcing ring outer diameter DR   mm
  Vessel shell thickness se   mm
  Reinforcing plate thickness s2   mm
  Reinforcing plate corner radius r2   mm
  Reinforcing plate width b   mm
  Reinforcing plate length l   mm
 
  Tension load Fe   kN
  Inclination angle β   °
  Stress load horizontal component Fx   kN
  Stress load vertical component Fy   kN
 
  Elastic modulus E   N/mm²
  Allowable pressure according to Hertz po all   N/mm²
  Allowable stress in the eyelet σall   N/mm²
  Allowable stress in connection weld σaV all   N/mm²
 
 

Calculation

  Pressure according to Hertz po   N/mm²
  Maximum stress due to bending load σM   N/mm²
  Maximum stress due to tension load σF   N/mm²
  Maximum stress in the eyelet at the hole σtot   N/mm²
  Maximum stress in eylet at weld due to bending load σM   N/mm²
  Maximum stress in eylet at weld due to tension load σF   N/mm²
  Maximum shear stress in eylet at weld τ   N/mm²
  Maximum stress in eylet at weld σ   N/mm²
  Maximum stress in connection weld due to bending load σaM   N/mm²
  Maximum stress in connection weld due to tension load σaF   N/mm²
  Maximum shear stress in connection weld τa   N/mm²
  Maximum stress in connection weld σaV   N/mm²
 

Results

  Pressure according to Hertz   po =  N/mm² po all =  N/mm²
  Maximum stress in the eyelet at the hole   σtot =  N/mm² σall =  N/mm²
  Maximum stress in eylet at weld   σ =  N/mm² σall =  N/mm²
  Maximum stress in connection weld   σaV =  N/mm² σaV all =  N/mm²
