This paper focuses on vibration suppression and energy harvesting using a non-traditional\nvibration absorber referred to as model B. Unlike the traditional vibration absorber, model B has its\ndamper connected between the absorber mass and ground. The apparatus used in the study consists\nof a cantilever beam attached by a mass at its free end and an electromagnetic energy harvester.\nThe frequency tuning is achieved by varying the beam length while the damping tuning is realized by\nvarying the harvester load resistance. The question addressed is how to achieve the best performance\nunder transient responses. The optimum tuning condition for vibration suppression is based on\nthe Stability Maximization Criterion (SMC). The performance of energy harvesting is measured by\nthe percentage of the harvested energy to the input energy. A computer simulation is conducted.\nThe results validate the optimum parameters derived by the SMC. There is a trade-off between\nvibration suppression and energy harvesting within the realistic ranges of the frequency tuning ratio\nand damping ratio. A multi-objective optimization is conducted. The results provide a guideline for\nobtaining a balanced performance. An experimental study is carried out. The results verify the main\nfindings from the computer simulation. This study shows that the developed apparatus is capable of\nachieving simultaneous vibration suppression and energy harvesting under transient responses.
