The ebook is the second one quantity of a set of contributions dedicated to analytical, numerical and experimental suggestions of dynamical structures, offered on the foreign convention "Dynamical platforms: thought and Applications," held in Łódź, Poland on December 7-10, 2015.
The stories supply deep perception into new views in research, simulation, and optimization of dynamical structures, emphasizing instructions for destiny study. largely defined subject matters coated comprise: bifurcation and chaos in dynamical structures, asymptotic tools in nonlinear dynamics, dynamics in existence sciences and bioengineering, unique numerical tools of vibration research, keep an eye on in dynamical structures, balance of dynamical platforms, vibrations of lumped and non-stop sytems, non-smooth structures, engineering structures and differential equations, mathematical ways to dynamical structures, and mechatronics.

The measuring circuit scheme of the MFC system is presented in Fig. 6. The output current 32 M. Borowiec et al. Fig. 5 The equipment of measuring stand measurement of piezoelectric circuit was realized by voltage measuring on resistor RP and ampliﬁed by Analogue Device AD620. Finally the signal was introduced to the acquisition card with DSP module. 5 Experimental Results At the beginning of the experimental measurements, the ﬁrst and the second resonance zones at 1g and 2g level of excitation have been estimated.
The values of the plots are normalised by the maximum value of acceleration amplitude at the open electrodes of each case piezoelement changes the stiﬀness of the beam while it is oﬀ or on. The numerical results provided, the dynamics of the MFC system can be controlled by included load subsystem. 4 Experimental Set-Up The laboratory experiments have been performed using electromagnetic shaker system TIRAvib 50101 presented in Fig. 5, which reproduced environmental conditions over a required frequency band.
