Forced oscillations with continuum models of atomic force microscopy
(2012-12-01)
The dynamics of the AFM-atomic force microscope follows a model based in a Timoshenko cantilever beam with a tip attached at the free end and acting with the surface of a sample. General boundary conditions arise when the ...
A load cell for grain-propelled ballistic rocket thrust measurement
(2005-12-01)
A 1000-kgf resistive strain-gauge load cell has been developed for quality testing of rocket propellant grain. A 7075-T6 aluminum alloy has been used for the elastic column, in which 8 uniaxial, 120-Ω strain gauges have ...
A nonlinear model and force control of a robotic claw
(Amer Inst Physics, 2014-01-01)
The objective of this work is to obtain and analyze a simple representative mathematical model for a robotic claw. The claw is represented here through the interaction between two simple pendulums and a sub-system composed ...

Experimental soil dynamic force: An improvement of Standard Penetration Test (SPT) interpretation
(2013-01-01)
The Standard Penetration Test (SPT) is widely used for geotechnical subsurface investigation. It is intended to provide soil properties and foundation design parameters. Schnaid et al. (2009) proposed a rational method to ...
Influência da geometria do martelo na determinação da força durante o ensaio de impacto Charpy-V
(2003-12-01)
The instrumentation applied to the Charpy test machine allows the accompaniment of the specimen answer front the impact load, in form of a sign characteristically dynamic representative of the deformation process and it ...
Vocal folds vibrations with a three-dimensional deformable model
(2006-12-01)
In this work a computational method is presented to simulate the movements of vocal folds in three dimensions. The proposed model consists of a mesh free structure where each vertex is connected its neighbor through a group ...
A semiconductor strain gage tactile transducer
(Institute of Electrical and Electronics Engineers (IEEE), 2001-01-01)
This paper describes the development of a semiconductor strain gage tactile transducer. It was designed with the goal of measuring finger forces without affecting the hand dexterity. The transducer structure was manufactured ...
Influence of nonlinear effects on the acoustic levitation of small spheres
(IEEEChicago, Illinois, 2014-09-03)
This paper presents the nonlinear characterization of a single-axis acoustic levitator and the analysis of the influence of nonlinear effects on the acoustic levitation of small spheres. First, the nonlinear characterization ...
Determination of the maximum force due to skull impact in fights between sheep of the Ovis aries species
(Wit Press, 2002-01-01)
The present article presents a means of determining the maximum impact force between two bodies from the determination of the involved impulse in the impact and the sound emitted by the shock of the bodies during this ...
