Apparatus for electromagnetically isolating an automobile
First Claim
1. An apparatus for electromagnetically isolating an automobile having road wheels from an environment surrounding the automobile, comprising:
- a first chamber for the automobile;
a second chamber disposed adjacent said first chamber;
means for shielding said first and second chambers from passing of electromagnetic wave between said first and second chambers and environments around said first and second chambers;
a wall disposed between said first and second chambers to cover said second chamber;
road simulator units mounted within said second chamber;
dynamometer means mounted within said second chamber in driving relation with said road simulator units;
blowers mounted within said second chamber;
a controller disposed outside said first and second chambers to prevent electromagnetic wave from entering said first and second chambers;
conductors connecting said controller with said dynamometer means and said controller with said blowers;
first filters disposed in said conductors to filter electromagnetic noise propagated from said controller to said dynamometer means; and
second filters disposed in said conductors to filter electromagnetic noise propagated from said controller to said blowers.

Abstract
An electromagnetic compatibility simulating apparatus for an automobile including an electromagnetically shielded cell having a wall dividing the interior of the cell into a first chamber for the automobile and a second chamber. Road simulator units are mounted within the second chamber. Dynamometers are mounted within the second chamber in driving relation with the road simulator units. The wall has windows for allowing driving contact of the road simulator units with the road wheels, and blower openings for allowing air feed from blowers. Electromagnetic wave absorbers and reflecting wall portions are disposed on the windows. Expanded metals cover the blower openings or metal pipes are disposed between the blower and the blower openings. The wall has inspection windows with shutters on which electromagnetic shielding net is disposed. A controller is disposed outside the first and second chambers. Conductors connect the controller with the dynamometers and blowers. First and second filters are disposed in the conductors.
