Abstract

Inertial sliders are positioning devices and are used to a position with a resolution ranging from few hundred nanometres to few millimeters. The inertial sliders are used in microprobe applications as they allow precise positioning, high resolution, practically unlimited travel range and can be made very compact. This work presents a finite element model to study the displacement due to friction model on stick-slip principle. In this work, finite element analysis involves mechanical and electro-mechanical coupled model. FEA of Lead Zirconium Titanate (PZT) plate is carried out under the mechanical model. The maximum displacement obtained for exponential input waveform. Finite element modeling of inertial slider subjected to different input waveforms such as linear, quadratic, cubic and exponential waveforms is carried out under the electro-mechanical coupled model and the results obtained are compared with semi-analytical results obtained by solving the differential equations derived from the lumped model, the results are directly compared to obtain good agreement.
