Embodiment
Below in conjunction with accompanying drawing and embodiment, patent of the present invention is further elaborated:
The present embodiment simulated earthquake carrys out provisional school's earthquake scene, seismic motion analog platform has totally nine induction zones, 1--induction zone, induction zone 9: this virtual earthquake simulating scenes escape analog demenstration platform Demonstration table is made up of earthquake virtual scene simulator and earthquake simulation motion platform (1).Earthquake virtual scene simulator sets up into by earthquake virtual scene simulator framework (2) presentation space that three are the U-shaped three degree of rear projection screen, is provided with short focus projector (4) after each rear projection screen.Earthquake simulation motion platform (1) is arranged in the middle of presentation space.Earthquake simulation motion platform (1) pedestal is underlying basis platform (6), the upper mounted motor (23) of underlying basis platform (6), motor (23) is connected with bearing 2 (31) by shaft coupling (22), bearing 2 (31) is arranged on (6) on underlying basis platform by bearing seat 2 (27), and bearing 2 (31) is connected with electromagnetic clutch 2 (20) by synchronous pulley 1 (24).Bearing 2 (31) is connected with bearing 1 (30) by gear (29), bearing 1 (30) is connected with electromagnetic clutch 1 (20) by synchronous pulley 2 (25), and bearing 1 (30) is arranged on underlying basis platform (6) by bearing seat 1 (26).Electromagnetic clutch 1 (19) and electromagnetic clutch 2 (20) are arranged on bearing (32), bearing (32) is arranged on underlying basis platform (6) by bearing seat (12) and goes up and be connected on reducer casing (21) with shaft coupling (22), reducer casing (21) is connected on screw mandrel (14) by synchronous pulley 3 (28), and reducer casing (21) is by being arranged on underlying basis platform (6).Screw mandrel (14) is installed ball wire bar pair (15), ball wire bar pair (15) is arranged on top layer basic platform (11), underlying basis platform (6) is provided with proximity switch 1 (16) and proximity switch 2 (17), proximity switch inductive head (18) is installed in top layer basic platform (11) position of proximity switch 1 (16), proximity switch 2 (17) top.Underlying basis platform (6) is connected with top layer basic platform (11) by several optical axis carrier bases (7), optical axis support (8), straight optical axis (9), slide block (10).Top layer basic platform (11) is provided with 1--induction zone, induction zone 9, installation infrared sensor (13) in 1--induction zone, induction zone 9.
