Support Plate Fretting Wear
Figure 4 - Outline of the finite element model used in the support plate investigation. Variable coil positions simulate the pull-through of a remote field probe. Each exciter area consist of a 3.2 x 3.2 mm (0.13 x 0.13 in.) region through which a total of 300 mA is carried.
Figure 5 - Zoom in of the mesh in the top region of the model. The region has been divided into three different areas, each shown separately. The total model consist of 9,500 triangle elements (10,000 is the maximum the solver can handle).
Figure 6 - Time averaged Polynting vector calculated at the pipe-plate interface. The pipe has no defect; the air gap is 0.476 mm (0.02 in.) wide. The exciter is located at 46.4 mm (1.86 in.) from mid plate, at the position shown, and carries 300 mA at 200 Hz. The figure shows a 40 x 40 mm (1.6 x 1.6 in.) zoom in. The widths of the arrows are proportional to the logarithm of the local Polynting vector.
