Solenoid under current load

finite element analysis of the mechanical stress in solenoid, magnetic forces in the solenoid

This is an example of the solenoid under current load simulation, performed with QuickField software.

Problem Type:
Axisymmetric problem of magneto-structural coupling.

Geometry:

Given:
Inner radius R1 = 5 mm;
Outer radius R2 = 10 mm;
Current density j = 4·10⁶ A/m²;
Coil Young modulus E = 1.075·1011 N/m²;
Coil Poisson ratio ν = 0.33.

Problem:
Calculate the stress distribution.

Result:
