High Capacity Variable Friction Damper based on Band Brake Technology
Implementation of high performance controllable damping devices can ameliorate cost-effectiveness of structural systems for mitigation of natural hazards. However, the applications of these damping systems are limited due to a lack of 1) mechanical robustness; 2) electrical reliability; and 3) large resisting force capability. To broaden the implementation of modern damping systems, a novel sem...
متن کاملVariable Friction Device for Structural Control based on Duo-Servo Vehicle Brake: Modeling and Experimental Validation
Supplemental damping can be used as a cost-effective method to reduce structural vibrations. In particular, passive systems are now widely accepted and have numerous applications in the field. However, they are typically tuned to specific excitations and their performances are bandwidth-limited. A solution is to use semi-active devices, which have shown to be capable of substantially enhanced m...
متن کاملDesign of High Capacity Wireless LANs Based on 802.11b Technology
The availability and low cost of 802.11b wireless networking products have encouraged a rapid growth in deployments of wireless LANs. As the use of powerful portable computing devices (laptops, PDAs) with WLAN adapters becomes a common expectation, the ability of wireless LANs to cater for large numbers of users with high bandwidth requirements is an increasingly important design consideration....
متن کاملAnalysis of Brake-Pad Friction Material Formulation
In the technologically advanced era that we currently live in, there is a growing demand for cheaper and more durable materials for a variety of purposes. The most important safety feature of an automobile is its braking system. The ability of brakes is to provide safe and repeatable stopping, which is related to safety of automobiles and human. Automotive friction materials are multi component...
متن کاملStructural Control Based on Semi-active Variable Friction Dampers
This paper discusses a methodology of semi-active structural control using a variable friction damper. The presented algorithm is quite simple and straightforward, in which only the slip level of the friction damper is controlled in response to the interstory response velocity of the damperinstalled story so as to maintain the target constant ductility factor. In conducting control there is adv...
