Solenoid under current load

QuickField simulation example

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

Problem Type
Axisymmetric multiphysics problem of DC magnetics coupled to Stress analysis.

Geometry
Inner radius R1 = 1 cm, outer radius R2 = 2 cm.
Solenoid under current load Calculate the mechanical stress distribution in the solenoid coil carrying current Winding R1 R2

Given
Current density j = 4 MA/m²,
Coil Young modulus E = 107.5 GPa, Poisson ratio ν = 0.33.

Task
Calculate the mechanical stress distribution.

Solution
In this example, we ignore the end effects and model the central part of the solenoid only.

Result
Flux density and mechanical stress distribution in solenoid under current load:
solenoid expansion under magnetic forces
