This paper describes the results of an extensive study on the seismic behavior of a structure with damper and without damper under different earthquake acceleration frequency like Earthquake Altadena, Earthquake Lucerne and Earthquake New Hall. It is observed through nonlinear time history analysis that maximum displacement, maximum base shear and maximum acceleration can be effectively reduced...

The planetary flywheel can significantly reduce the weight of flywheel, allowing inerter to be lightweight. When a ball screw inerter-based active actuator is used in vehicle suspension system, nonlinear features affect performance. actuator’s dynamic model constructed this study based on and electromagnetic torque generating mechanism permanent magnet synchronous motor. impact screw–nut fricti...

The aim of this study was to validate different theoretical performance models using subscale wave tank tests. The device modeled is a heaving point absorber working against a submerged reaction plate. This type of device has been pursued by a number of commercial and is therefore relevant as a benchmark for future efforts on similar devices. A set of model tests were carried out at 1:33 scale ...
