In recent decades, with the increase of energy demand and the development of wireless and micro-electro-mechanical technology, research in the field of energy recovery has been paid more and more attention. Because of piezoelectric materials can transform mechanical strain energy into electrical charge, therefore, piezoelectric materials are the major method of energy scavenging. The research status of piezoelectric energy harvesting devices at domestic and overseas is presented in detail. This paper includes four aspects: Asingle-degree of freedom system, piezoelectric cantilever beam, energy harvesting circuit and topology optimization of energy harvester. The development perspective of the piezoelectric vibration energy harvester was summarized. The study will be helpful for the researchers who are engaged in the studying on the piezoelectric vibration energy harvesting.

Boring bars are widely used in deep hole machining. Due to the low stiffness of the long cantilever boring bar, vibration often occurs in the boring process. Vibration suppression can permit higher productivity and a better surface finish. To improve the performance of boring operations, a variable stiffness dynamic vibration absorber (DVA) is added inside the boring bar to reduce the vibration. The stiffness of the DVA is provided by two rubber bushes placed inside the DVA. By changing the axial compression, the stiffness of the DVA can be adjusted to accommodate different excitation frequencies. By establishing the relationship between the stiffness of the DVA and the axial compression of the rubber bush, the optimal stiffness for different excitation frequencies can always be found. A boring experiment is conducted, and the results show that, by selecting a reasonable axial compression, the vibration of the boring bar can be effectively suppressed.

“…Recently, Omidi and Mahmoodi (2016) proposed a robust method which can suppress the vibration even if the observer could not successfully estimate the vibrational behavior, by devising an electrical circuit controlling the piezoelectric elements. Moreover, hybrid methods that combine passive and active methods (Matsubara et al, 2014;Yamada et al, 2014), have been investigated. The investigated methods could suppress vibration stability by a passive damping method, and simultaneously provide a highly effective suppression of the vibration by application of an active damping method.…”

This study demonstrates a novel method for vibration damping using a piezoelectric element. A piezoelectric transducer excited by ultrasonic vibrations is placed in contact with a vibrating object in a direction perpendicular to the vibration. In conventional methods, piezoelectric elements attached to vibrating objects are excited in the same direction as the vibration direction of the object. Such methods require complicated control and measurements for maintaining the vibration of the transducer in the phase opposite to the object's vibration, to exert the damping effect. In contrast, the proposed method does not require adjustment of the transducer's vibration phase according to the object because this method manipulates a friction loss between the transducer and a vibrating object for damping. This study confirmed a damping effect with the proposed method by conducting hammering tests on a cantilever. Furthermore, the parameters influencing the damping effect and the damping principle were considered. The damping ratio obtained from these tests was approximately 10 times the value when a non-excited transducer was statically pressed to the cantilever. Moreover, the test results suggested that the magnitude of the damping effect could be estimated by measuring the current flowing in the transducer, and that an optimal current to achieve the highest damping effect exists. The damping effect by the proposed method is considered to be triggered with a slip between the transducer and a vibrating object by suppressing the transverse oscillation of the transducer using the inertia effect caused by the transducer's excitation. Furthermore, the increase of the impact force applied to the object by the excitation improves the damping effect. By measuring the stress waves in a long bar based on the one-dimensional elastic wave propagation theory, the impact force caused by the excited transducer was measured. The impact force had a peak at a specific current and changed with the same tendency as the damping ratio. The results suggested that both suppressing the transducer's transverse oscillation and increasing the impact force cause the high damping effect by using the proposed method.
