Secondly, when the common pot-type rubber support is used, the adjustment of large displacement can be realized, the anti-pulling function or the vertical height-adjusting function can also be realized independently, but the combination of the anti-pulling function and the vertical height-adjusting function can not be realized, and the transverse torsion-resisting function can not be realized, so that the pot-type rubber support can not be used for a magnetic suspension track bridge. And thirdly, although the common spherical support has a stable and reliable structure, the common spherical support has a single function, can only realize the functions of bearing, turning, displacement or pulling resistance, and obviously cannot meet the design requirements of the magnetic suspension track bridge.
