  1. More on the deflect-o-meter results 6-30-06

  2. Test case is 36.5 kamps/turn Model does not account for the overstocked condition of the winding form/tee. Legs in this model are simple extrusions from the casting Node 76307 How Deflection is measured (known location) X direction Mounting location Locked post Node 76898

  3. Results revisited with the updated location of the deflect-o-meter Real Pad updated model showing the deflect-o-meter path

  4. Restraints Again Deflect-o-meter prediction = .32 mm Deflect-o-meter prediction = .54 mm One post fixed, three posts sliding on a plane All posts fixed in all directions In both cases, the left front leg (north-west when viewed from above) is treated as always touching the floor. What if that leg actually moved up and the coil was essentially supported on a tripod. The magnetic field tends to want to push that leg off the floor (see the red area on the figure on the right). By supporting it as I have here, I am forcing the coil to move and bend to accommodate my displacements, an unwanted effect.

  5. Picture of how leg is held vertically It is unclear from this view how the top plate, which is intended to restrict lateral movement, is touching the support vertically or if there is a gap of some size. Even if the leg is touching the plate, the plate is probably not suitable to restrain all vertical movement Leg Top lateral support plate

  6. Letting the north-west leg go (400 µE) Northwest leg wants to move up and the coil is then supported by three legs The leg moves up 4-5 mm (vertical) For 400 uE, the deflect-o-meter ANSYS reading is 0.28 mm 400 µE

  7. Letting the north-west leg go (0 µE) Northwest leg wants to move up and the coil is then supported by three legs The leg moves up 4.5-5.5 mm (vertical) For 0 uE, the deflect-o-meter ANSYS reading is 0.21 mm 0 µE

  8. New Updated Table Using a simple linear trend (obviously more points are needed), the results tend to suggest that differential strain may be less than 400 uE.
