Fluid Damper

Magnetic fluid damper is a kind of shock absorber which based on the principle of second-order buoyancy of magnetic fluid. In this paper, the structure of magnetic fluid damper is analyzed firstly, and then a variety of structural parameters on the damping effect are tested. Focusing on the different gasket angles in the damper, we found that gasket angles play a key role in the damper to influence on the damping effect. A corresponding model is put forward to analyze the inherent reasons.

Foam Metal

A new kind of damper with magnetic fluid(MRF)/foam metal designed by us is introduced, and it’s damp model is established. Semi-active controlling shock absorber with the damper is designed, and it’s dynamic module is established. Fuzzy control on chatter system is designed by fuzzy controlling theory. Finally, simulation on it is done by matlab /simulink. It is shown that the control system can restrain the chatter very well.

Tissue from the hood and sarcophagus regions were fixed in 6% glutaraldehyde in 1 M.cacodylate buffer and washed in buffer. Tissue for SEM was partially dried, attached to aluminium targets with silver conducting paint, carbon-gold coated(100-500Å), and examined in a Kent Cambridge Stereoscan S4. Tissue for the light microscope was post fixed in 1% aqueous OsO4, dehydrated in acetone (4°C), embedded in Epon 812 and sectioned at ½u on a Sorvall MT 2 ultramicrotome. Cross and longitudinal sections were cut and stained with PAS, 0.5% toluidine blue and 1% azure II-methylene blue. Measurements were made from both SEM and Light micrographs.The tissue had two structurally distinct surfaces, an outer surface with small (225-500 µ) pubescent hairs (12/mm2), numerous stoma (77/mm2), and nectar glands(8/mm2); and an inner surface with large (784-1000 µ)stiff hairs(4/mm2), fewer stoma (46/mm2) and larger, more complex glands(16/mm2), presumably of a digestive nature.
