Sketch the wave shape, and donut

Surface> Extrude the wave,

then Solid > Extrude > Intersect the donut. 

Thicken the washer.

Might help....

Make one, copy twice and move them to where you want them.

I am not totally sure what part is not working.

The attached should be pretty close to what you want.  I made the number of wave parametric, so you can change it via the change parameters dialog box.  you have to fix the final combine if you change the number of waves.
