this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...

To facilitate the damping matching of dampers for vehicle passive suspensions, this paper proposes an analytical matching method of the optimal piecewise linear damping characteristics curve. Based on the vehicle vibration model, taking the suspension dynamic deflection as the constraint, by the vibration acceleration and the wheel dynamic load, an objective function about the relative damping ...

Toward the general goal ofpreventing ankle injuries in snowboarding accidents, the E. Wang objective of this project to develop a dynamic system model of a snowboarder and Assistant Professor, assess which model parameters, particularly those attributed to the boot, most Department of Mechanical Engineering, strongly influenced ankle deflections during a forward fall. To satisfy this objective,...

This paper presents dynamic modelling of a two-link flexible manipulator system. The kinematic model is based on standard frame transformation matrices describing both rigid rotation and modal displacement, under small deflection assumption. A two-link flexible manipulator incorporating structural damping, hub inertia and payload is considered. An explicit, complete, and accurate nonlinear dyna...

Epsilon-near-zero nanoantennas can be used to tune the far-field radiation pattern due their exceptionally large intensity-dependent refractive index. In this study, we propose a hybrid optical antenna based on indium tin oxide (ITO) enable tuning of deflection radiation, specifically structure ITO and dielectric material, which makes angle changes 17∘ as incident intensities increase. Moreover...

This paper analyzes the usability of different dynamic moduli of elasticity and wood density for the prediction of mechanical properties – static modulus of elasticity and modulus of rupture – in samples with grain deflection from the longitudinal direction. Five tropical hardwoods (Afzelia bipindensis, Intsia bijuga, Millettia laurentii, Astronium graveolens and Microberlinia brazzavillensis) ...
