Energieverlust des Vibrationssystems

Sie hängt allein von der Geschwindigkeit (v) des schwingenden Körpers ab. Die andere Energieform hängt allein von der Auslenkung (y) des schwingenden Körpers ab. Wir

Why are vibration energy harvesters used in vehicle regenerative based suspensions?

Among various vibration energy harvesting structures, the electromagnetic harvesters have gained popularity in vehicle regenerative based suspensions because of the high-energy conversion efficiency, quick response, strong controllability, and capability in energy recovery , , .

What is the theory of vibration of continuous systems?

The vibration of such systems is governed by partial differential equations which involve variables that depend on time as well as the spatial coordinates. In this chapter, an introduction to the theory of vibration of continuous systems is presented.

What is vibration harvesting system?

While in other applications as in automobiles, the vibration harvesting system is considered as a subsystem in which the power recycling is not the sole purpose but it should provide acceptable dynamic performances (road holding, and ride quality) comparing to the traditional suspensions. Fig. 34.

Why is Energy conserved during a free vibration?

As discussed in Chap. 2, the fact that the energy of the system, during the undamped free vibration , is conserved can be utilized to derive the equations of motion. To this end, one can write

Does free undamped vibration conserve energy?

Recall from the analysis presented in the preceding section that in the case of free undamped vibration , the energy associated with any mode of vibration is conserved. The sum of the kinetic energy and strain energy of a mode remains constant and equal to the maximum kinetic energy or equal to the maximum strain energy.

How can vibration mitigation and energy harvesting be realized?

Vibration mitigation (VM) and energy harvesting (EH) can be realized by the VI DEO and the proposed RVI DEO. The transient dynamics and harmonic forced dynamics are investigated. The VM and EH performances of the two DE oscillators are investigated for diverse parameters.
