| Abstract: | 3D electromagnetic fields FE analysis of a magnetic valve used in the electronically controlled diesel engine was carried out by using ANSYS. At certain air gap and current, static electromagnetic characteristics of the electromagnet were analyzed. Some factors such as working area, coil turns, core number, armature depth and iron material that influence the magnet force were discussed in detail. Experiment result indicates that the calculation is correct, and the finite element model can direct the design of magnet valves because of its relatively high precision. |
