“…Los edificios sin estos dispositivos sobreviven el sismo severo disipando energía en sus elementos principales, los que finalmente sufren el mayor daño. Si la estructura es sometida a deformaciones que puedan llegar a ser excesivas, esto se podría reflejar en un desempeño estructural deficiente, que podría conducir a situaciones altamente indeseables, tal como los elevados costos de rehabilitación por los daños en los elementos no estructurales [31].…”

Las cargas que generan los eventos sísmicos y los fuertes vientos son fuerzas de la naturaleza que someten a las obras civiles a situaciones extremas, lo que provoca eventualmente la falla de las estructuras y en muchas ocasiones, la pérdida de vidas humanas. Para enfrentar estas fuerzas de carácter aleatorio y de difícil predicción, la ingeniería estructural plantea normativas de diseño y construcción de obligatorio cumplimiento en la mayoría de los países del mundo, que permiten que las estructuras puedan resistir de manera adecuada las fuerzas impuestas. Y como la historia lo ha demostrado, algunas veces un buen diseño no es suficiente, por lo que la ingeniería sismoresistente desarrolla nuevas metodologías y dispositivos que ayuden a proteger aún más a las estructuras cuando se ven sometidas a acciones como los sismos y los vientos. Para afrontar estos retos, aparecen mecanismos como los amortiguadores y controladores, agrupados como dispositivos pasivos, activos, semiactivos e híbridos, con diseños innovadores que contribuyen en gran medida a dar mayor seguridad y confianza a nuestras obras civiles. En este artículo se presenta una visión general de los amortiguadores de masa sintonizada, su desarrollo histórico, modelos mecánicos y analíticos, alcances, fortalezas y debilidades. The loads generated by seismic events and strong winds are forces of nature that subject civil works to extreme situations, generally causing the failure of structures and in many cases, the loss of human lives. In order to face these forces of random character and difficult to predict, structural engineering proposes design and construction regulations that are mandatory in most countries of the world, which allow the structures to adequately resist the imposed forces. And as history has shown, sometimes a good design is not enough, so seismic-resistant engineering develops new methodologies and devices that help to further protect structures when they are subjected to actions such as earthquakes and winds. In order to face these challenges, mechanisms such as shock absorbers and controllers appear, grouped as passive, active, semi-active and hybrid devices, with innovative designs that greatly contribute to give greater safety and confidence to our civil works. This article presents a general overview of seismic dampers and controllers, their historical development, mechanical and analytical models, scopes, strengths and weaknesses.

“…For example, magnetorheological dampers [ 27 ], which incorporate magnetic particles suspended in a viscous liquid, can alter their rheological properties by the application of an external magnetic field [ 28 , 29 ]. In other cases, the application of external energy to a motor acting on the suspension allows the appropriate damping characteristic to be achieved [ 30 ]. Recently, studies on energy recovery dampers have shown that it is possible to change the comfort characteristics by varying the electrical parameters of the generator [ 13 ].…”

Energy harvesting shock absorbers (EHSA) have made great progress in recent years, although there are still no commercial solutions for this technology. This paper addresses the question of whether, and under what conditions, an EHSA can completely replace a conventional one. In this way, any conventional suspension could be replicated at will, while recovering part of the wasted energy. This paper focuses on mimicking the original passive damper behavior by continuously varying the electrical parameters of the regenerative damper. For this study, a typical ball-screw EHSA is chosen, and its equivalent suspension parameters are tried to be matched to the initial damper. The methodology proposes several electrical control circuits that optimize the dynamic behavior of the regenerative damper from the continuous variation of a load resistance. The results show that, given a target damper curve, the regenerative damper can adequately replicate it when there is a minimum velocity in the damper. However, when the damper velocity is close to zero, the only way to compensate for inertia is through the introduction of external energy to the system.

“…In Karnopp’s study (1989), a linear permanent magnet machine that can be used as a variable damper was presented, but it did not go deep into the semi-active suspension system operation. Some other references explain aspects of semi-active damping systems without specifying the type of shock absorber, for instance, Ezeta et al (2013) and Jalili (2002) discussed semi-active suspension systems but did not mention electromagnetic dampers. Paulides et al (2006) used analytical and numerical resources to recommend a design of tubular linear damper for semi-active suspension systems.…”

Purpose Semi-active suspension systems with electromagnetic dampers allow energy regeneration and the required control strategies are easier to implement than the active suspensions are. This paper aims to address the application of a tubular linear permanent magnet synchronous machine for a semi-active suspension system. Design/methodology/approach Classical rules of mechanics and electromagnetics were applied to describe a dynamic model combining vibration and electrical machines theories. A multifaceted MATLAB®/Simulink model was implemented to incorporate equations and simulate global performance. Experimental tests on an actual prototype were carried out to investigate displacement transmissibility of the passive case. In addition, simulation results were shown for the dissipative semi-active case. Findings The application of the developed model suggests convergent results. For the passive case, numerical and experimental outcomes validate the parameters and confirm system function and proposed methodology. MATLAB®/Simulink results for the semi-active case are consistent, showing an improvement on the displacement transmissibility. These agree with the initial conceptual thoughts. Originality/value The use of linear electromagnetic devices in suspension systems is not a novel idea. However, most published papers on this subject outline active solutions, neglect semi-active ones and focus on experimental studies. However, here a dynamic mechanical-electromagnetic coupled model for a semi-active suspension system is reported. This is in conjunction with a linear electromagnetic damper.
