TEST DEVICE

摘要

[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 in a small 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, anda magnetizing device 40, which is disposed on 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 in which an air pressure of the air bearing 34 is high, the magnetizing force to the slipping floor 12 of the magnetizing device 40 is strong, andin the non-operating state in which an air pressure of the air bearing 34 is low, the magnetizing force to the slipping floor 12 of the magnetizing device 40 is weak.

主权项

1. A test device according to a driving operation of an operator to simulate a driving state, comprising:
a base plate, which can be moved on a slipping floor in directions of X-Y by an air bearing, and is disposed so that the base plate can be moved freely to rotate around a Z axis, a platform, which is connected on the base plate by a movement connecting mechanism, and in which a part to be driven is provided, and a magnetizing device, which is disposed on a lower surface of the base plate to face the slipping floor, and in which a magnetizing force to the slipping floor can be changed, wherein, in an operating state in which an air pressure of the air bearing is high, the magnetizing force of the magnetizing device to the slipping floor is strong, and in a non-operating state in which the air pressure of the air bearing is low, the magnetizing force of the magnetizing device to the slipping floor is weak.
