The invention discloses a magnetic suspension
supergravity vibration table, and relates to the field of
engineering anti-seismic research
test equipment, and the vibration table comprises a test cavity which is formed by the downward sinking of the ground, a first annular permanent
magnet guide rail is fixedly arranged on the inner side wall of the test cavity, and a second annular permanent
magnet guide rail is fixedly arranged on the bottom surface of the test cavity. The vehicle body
model test chamber is provided with a superconducting block, the rotation
radius of the vehicle body
model test chamber is greater than 20 meters, the
rotation test chamber is arranged in the vehicle body
model test chamber and is rotatably connected with the vehicle body model
test chamber through a pivotal bearing, and a vibration table is arranged in the
rotation test chamber; underground rock serves as a carrier of the first annular permanent
magnet guide rail and the second annular permanent magnet guide rail, the rotation
radius of the vehicle body model
test chamber is larger than 20 m, the
system error is reduced to 1% or below, and the test precision can be effectively improved. The volume of the rotary
test chamber is increased, the vibration table has sufficient three-direction vibration space after being placed in the rotary test chamber, and the requirement of an
earthquake simulation test is met.
