An efficient analytical solution for nonlinear vibrations of a parametrically excited beam
An efficient and accurate analytical solution is provided using the homotopy-Pade technique for the nonlinear vibration of parametrically excited cantilever beams. The model is based on the Euler-Bernoulli assumption and includes third order nonlinear terms arisen from the inertial and curvature nonlinearities. The Galerkin’s method is used to convert the equation of motion to a nonlinear ordin...
متن کاملPull-In Instability and Vibrations of a Beam Micro-Gyroscope
Gyroscopes are used as rotation rate sensors. Conventional gyroscopes are heavy and bulky, which creates important problems regarding their usage in different applications. Micro-gyroscopes have solved these problems due to their small size. The beam micro-gyroscope is one of the popular types of inertial sensors. Their small dimensions and low energy consumption are key reasons for their popul...
متن کاملAmplification, Attenuation, and Integration
9 have long been used to model networks of interacting neurons (Er10 mentrout, 1998; PHASE PLANE ANALYSIS OF NEURAL NETS). The 11 activity of neuron i is represented by a single dynamical variable 12 xi, and its input-output characteristics by a single transfer function 13 f. There are more biophysically realistic descriptions of neural net14 works that include many dynamical variables per neur...
متن کاملNonlinear parametric amplification and attenuation in a base-excited cantilever beam
This work investigates the nonlinear behavior of a representative parametrically amplified macroscale structure. Specifically, the effort examines the effects of structural and inertial nonlinearities on the near-resonant response of a base-excited, flexible cantilever beam driven by a combined (simultaneously parametric and direct) excitation. The prototypical structure is modeled using classi...
متن کاملRobust attenuation of direct-drive robot-tip vibrations
This paper suggests and employs a method for reducing vibrations at the tip of a robot. The vibrations, caused by structural flexibility, are detected using accelerometers. The robot control system consists of two complementary sub-systems: a nominal motion controller and a vibration compensator. The former one realizes joint motions in accordance with a prescribed tip trajectory. The latter on...
