SimulationEstimation or determination of model parameters for discrete element method (DEM) is an area of growing interest with the objective of providing robust methods combining single particle and bulk measurements.DEM simulation is implemented by a spring-dashpot model from the contact model,which ...
The Kelvin model, a spring and a dashpot used in combination with a gap element, is used in SAP 2000 program to simulate the pounding phenomenon. The pounding effects are first studied. The study concerns adjacent structures having ... W Viviane 被引量: 7发表: 2007年 Effect of soil-struc...
Together with analytical-empirical models, a vibrational spring-dashpot model is presented, which characterizes the impact force, contact time, and damping ratio/coefficient of polishing media upon impact; as well as the effects of damping on contact parameters: stress, deformation, and area of ...
This model has extremely simple mathematical structure and has very clear physical meaning. It can capture the features of dynamics of elastomer in wide range, from linear to nonlinear. This model has been used to analyze and explain the nonlinear dynamic behavior of an unfilled cured rubber ...
Continuous contact modelThe soft-sphere model design of the discrete element method is based on types of dynamic systems for determining the contact forces. These forces are computed considering the solution of equation of motion for the overlap between the particles during the contact. The dynamic ...
continuous contact model•It is proposed the use of a continuous damping force model for DEM simulations.•New relations for damping coefficient and contact duration are presented.•The continuous contact model is applied in gas-solid and granular flows....
Different combinations of dampers in different positions were employed to study the effects of multiple dampers in an individual plate model to examine the energy flow phenomenon in the presence of many dissipative elements. The structural intensity of plate structures connected by loosened bolts ...
A time history analysis of a sway-rocking model is conducted. The seismic responses based on acceleration response have a little underestimation compared with those by the time history analysis.M. IibaK. MiuraY. UmemuraO. Kurimoto
Numerical simulation of a drag-reducing turbulent channel flow due to polymer is performed. The beads-spring-dashpot chain model is employed as a model of polymer. The model consists of beads, springs, and dashpot to represent polymer dynamics. Energy exchange between the polymer and the fluid...
