Abstract

En 中文
In the present study the vibration analysis of a functionally graded porous nanobeam mass sensor carrying multiple mass-spring-damper attachments has been performed using an analytical method. A nonlocal strain-gradient theory is utilized in conjunction with a unified Higher-Order Shear Deformation Beam Theory (HSDT) to give the governing equations of the motion of the nanosensor. Effect of various parameters and theories on the frequencies of the nanobeam have been studied comprehensively and illustrated graphically. It has been shown that if the attached particle has a degree of elasticity, modeling it as a lumped rigid particle, directly attached to the sensitive frequency based micro/nano sensors can result in considerable error. Therefore the attached particles should be modeled as mass-spring systems in vibration analysis of nano mass sensors.
