Maxwell transient simulation of electromagnetic gun with external circuit
Since the ANSYS external circuit editor is not mentioned in many tutorials, the blogger writes it here so that everyone can learn from each other. Maxwell simulation electromagnetic gun external circuit
This tutorial will not teach basic operations. You can go to station B to find basic tutorials for basic operations. This blog focuses on the basic application of Maxwell circuir editor.
1. Create a new 2D simulation and select transient as solution type
2. Build the model as shown below and set the calculation domain, but you need to add a motion domain
The parameters of the aluminum bullet are inner diameter 10mm, outer diameter 15mm, and length 20mm.
The drive coil has an inner diameter of 20mm, an outer diameter of 36mm, and a length of 30mm.
3. Set up materials
4. Set up the finite element mesh of the bullet and the drive coil
The aluminum spring grid is 2mm and the drive coil is 4mm.
5. Set up incentives:
Add 60 turns of coil and add winding
Add the coil to the winding (there is only one winding, just confirm it)
6. Write the external circuit
Open the circuit editor
Find components in the area to connect the circuit
To set up MODLE, the process is as follows:
The setup process for the diode is the same as for the diode
Setting the winding
Export the circuit as an sph file
7. Import external circuit
Then determine it directly (because there is only one coil corresponding to the winding, if it is a motor simulation, the external circuit and multiple windings need to correspond separately)
8. Add force to the bullet
(Just confirm it directly)
9. Motion domain settings
Select the motion domain:
10. Set up Analysis
11. Add conditions to consider the eddy effect of the bullet
12. Check and analyze the results
Set the area to view the bullet vortex
13. Use animation to view the movement of bullets and changes in vortex
