[Problem] The invention is to provide a test device,
in which the weight of the platform that is the moving part is light, and the rigidity is high,
and in which a movement steady with a light base can be achieved,
and in which the simulation up to a high frequency is possible by small power and little space,
and in which it is cheap and compact. [Resolution Approach] The test device of the invention comprising:
a platform 18, which is connected on the base plate 14 by a movement connecting mechanism 16, and in which a parts to be driven 30 is provided, and
a magnetizing device 40, which is disposed to a lower surface of the base plate 14 to face the slipping floor, and in which magnetizing force to the slipping floor 12 can be changed,
wherein, in the operating state at a high air pressure of the air bearing 34, the magnetizing force to the slipping floor 12 of the magnetizing device 40 is a strong state, and
in the non-operating state at a low air pressure of the air bearing 34, the magnetizing force to the slipping floor 12 of the magnetizing device 40 is a weak state. |
