Abstract:
In this paper, we introduce certain models which arise in investigating some vibration problems of bio-inspired, vibrissa-like sensor models. Some approaches to the modeling of the biological paragon vibrissa use rigid body models in which a rod-like vibrissa is supported by a combination of spring and damping elements modeling the viscoelastic properties of the follicle-sinus complex. However, all the rigid body models can only offer limited information about the functionality of the biological sensory system. Therefore, we deal with bending problems of continuous beam systems. We present various beams with different supports (clamped and pivoted with discrete viscoelastic couplings) which are to model the biological tissues. This is new in and different from literature. We focus on investigations of the natural frequency spectra of various systems. The knowledge of dynamical characteristics is important for the design of artificial sensors. A close examination of vibrissa-like beam models with boundary damping exhibits features which are unlike in comparison to classical vibration systems.
