DESIGN AND EXPERIMENTAL TESTS ON NEW ADAPTIVE CONTROLLED ELASTICITY & DAMPING (ACED) MECHANICAL DEVICES

摘要

The paper presents the concept, design, manufacture and experimental tests of new adaptive controlled elasticity & damping (ACED) mechanical devices. The two types, ACED-B and ACED-I devices, provide the control of structures behaviour during dynamic and especially seismic loadings. The technical solution is part of a Romanian invention. In order to highlight the possibility of making ACED devices with the desired stiffness and damping properties, a series of experimental tests have been conducted with different setups of the elastic sandwich structures and several geometric shapes of the device deforming parts.
