The Earthquake Response Analysis of Isolation Structure with Piezoelectric Friction Damper
A new intelligent isolation system combining a piezoelectric damper with laminated rubber bearing is proposed. and used in a practical example in this paper, LQR and GPC chose as the control algorithm according to the damper. The characteristic of these two kinds of algorithm is analyzed and is used in the civil engineering vibration controlling. The results of the analysis show the performance...
متن کاملFriction and the Inverted Pendulum Stabilization Problem
Abstract We consider an experimental system consisting of a pendulum, which is free to rotate 360 degrees, attached to a cart. The cart can move in one dimension. We study the effect of friction on the design and performance of a feedback controller, a linear quadratic regulator, that aim to stabilize the pendulum in the upright position. We show that a controller designed using a simple viscou...
متن کاملEarthquake Analysis of Spatial Rod Systems
A master element to be employed as a general spatial rod finite element is presented. This spatially curved and pretwisted element can have variable cross-section and variable curvature change. It may also be resting on an elastic foundation. Also, a finite element formulation for a general earthquake analysis of spatial rods is presented. The theoretical foundation has lead to a general-purpos...

objective: to investigate the friction of rabbit’s knee joint with designed pendulum friction tester to diagnose and evaluate different pathological and therapeutic conditions following haemarthrosis, osteoarthritis, and other joint disorders. materials and methods: friction coefficient of 10 adult male albino rabbit’s joint (5 right and 5 left knees) weighted 1.59 ± 0.27 kg, after designing a...
متن کاملEarthquake Response of Adjacent Structures with Viscoelastic and Friction Dampers
We study the seismic response of two adjacent structures connected with a dry friction damper. Each of them consists of a viscoelastic rod and a rigid block, which can slide without friction along the moving base. A simplified earthquake model is used for modeling the horizontal ground motion. Energy dissipation is taken by the presence of the friction damper, which is modeled by the set-valued...
