Static Balancing of Four-Bar Linkages with Torsion Springs by Exerting Negative Stiffness Using Linear Spring at the Instant Center of Rotation
(ASME, 2020-08-19)
A design approach for the quasi-static balancing of four-bar linkages with torsion springs is proposed. Such approach is useful on the design of statically balanced compliant mechanisms by setting the stiffness of the ...
On the undamped free vibration of a mass interacting with a Hertzian contact stiffness
(2011-12-01)
Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...
A numerical solution and evaluation of dynamic stiffness of pile groups and comparison to experimental results
(Elsevier, 2017)
A number of solutions and computer programs are already available to determine the dynamic stiffness of complete pile foundations, assuming linear elastic soil behavior and perfect bonding between the piles and the surrounding ...
A numerical and experimental study of bearing stiffness of drilled shafts socketed in heterogeneous rock
(Brasil, 2012)
The objective of this study is to evaluate the effect of spatial variability of rock elasticity on the tip resistance of drilled shafts using experimental tests, finite element analysis (FEA) and geostatistical principles. ...
High-static-low-dynamic-stiffness vibration isolation enhanced by damping nonlinearity
(2018-01-01)
High-static-low-dynamic-stiffness (HSLDS) nonlinear isolators have proven to have an advantage over linear isolators, because HSLDS nonlinear isolators allow low-frequency vibration isolation without compromising the static ...
Implicit, semi-analytical solution of the generalized Riemann problem for stiff hyperbolic balance laws
(Elsevier, 2015)
We present a semi-analytical, implicit solution to the generalized Riemann problem (GRP) for non-linear systems of hyperbolic balance laws with stiff source terms. The solution method is based on an implicit, time Taylor ...
