Numerical simulation based on finite element method and experiment of aerostatic bearing system;

The shortcommings of locally manufactured supports for IPB crossover sections are discussed, simultaneously pointing out the necessity of using floating supports.

In this paper,on the base of analysing multi-level helical gear transmision Of the reducer gear in central drive,making use of the founded dynamic model with torsional flexuable vibration,the stiffness and damping of suspension bearing are researched with The influence of gear transmision dynamic characteristic.

Using new technologies of static pressure bearing, static pressure guide and gas bearing, the mold of fresnel lenses mirror was precisely manufactured.

A vertical hard bearing two-plane dynamic balancing machine,based on gas bearing technique,was designed,and corresponding mathematic model was established.

Based on the analysis of one type high-speed gas bearing working principle, the bearing diameter of axle static carrying force model was set up, and the relationship between bearing clearance gas flow rate, intensity of pressure and orifice radius were analyzed, along with the diameter of axle movement tracking under the centrifugal force in the low rotating speed was found.

Dynamics analysis of air bearing with ultra-precision in vertical direction;

A new method based FEMLAB was developed to predict static performance of air bearings.

Based on air bearings,a ground experiment system for optimizing the 3-DOF space manipulator reaction is set up.

The practice on optimizing the magnetic suspension bearings of minimum weight staler shows that it is effective to minimize problems with CSDS method.
