Design method and device of anti-impact vibration isolation type magnetorheological pier bearing-damper system

ActiveCN104179118AInhibition shiftEnhanced vertical strengthBridge structural detailsElastomerDamping ratio
The invention relates to a design method and a device of an anti-impact vibration isolation type magnetorheological pier bearing-damper system. According to the method, magnetorheological elastomers which are large in vertical stiffness, high in structural strength and adjustable in elasticity modulus are used as bearing bodies, and impact resistance and vibration isolation of a pier-beam structure under the action of large load are realized by adjustment of pier stiffness; a magnetorheological damper capable of providing large damping without medium settlement is used as a damping device, three-dimensional rotation capacity of the damper is improved by using a ball-and-socket joint mode at two ends thereof, and pier-beam displacement is restrained by damping adjustment for further vibration reduction and energy dissipation; magnetorheological elastomer bearings, the magnetorheological damper and a controller jointly form an anti-impact vibration-isolation pier bearing device, the controller intelligently adjusts stiffness and damping of the bearing-damper system by detecting the impact vibration of a bridge, structural strength of the pier-beam structure is improved while damping ratio thereof is increased, and when the bridge is under large-load impact vibration, impact transmission is slowed down or isolated and pier-bean displacement is restrained so as to guarantee structural safety of the bridge.

Castable kiln structure of cylindrical heat rotary equipment

Disclosed is a castable kiln structure of cylindrical heat rotary equipment. The castable kiln structure is characterized in that a kiln body is divided into a low-temperature feeding region, a high-temperature heat reaction region and an outlet and flow port. Retaining rings are arranged on regional boundaries of the low-temperature feeding region, the high-temperature heat reaction region and the outlet and flow port. The retaining rings protrude out of a kiln liner, so that the materials are enabled to turn over and change operation orbits through the retaining function of the protrusion height of the retaining rings when materials enter different temperature regions. The shortcomings that the kiln liner shaking during operation of a traditional bricked kiln liner to be separated from a steel casing to produce slip frequency with the same is free of overall strength, the kiln liner can be loosened and disintegrated instantly and cannot be maintained rapidly in a small range, and the like are effectively overcome, so that service life of the cylindrical kiln liner is prolonged by one to several times as compared with that of the bricked kiln liner, working cavities inside the kiln liner can be optionally changed according to technological requirements, damages to certain parts of the kiln liner do not cause affect to the service life of the whole kiln, and rapid maintenance in the small range can be achieved.
