چکیده
Abstract The elastic deformation of the links in robot mechanisms affects precision their motion and fatigue strength. Kineto-elastodynamics (KED)-the dynamics analysis that considers elasticity links-emerged early studies has been subject extensive research applications since. However, there have no reports on effects kinematic pair clearances vibration mechanisms. This is mainly because finite element (FE) model developed for describing KED linkage In this study, an FE was proposed clearances. mass matrix obtained by considering lumped masses pin bearing. stiffness based moduli pin-bearing pair. applied to modeling verified through simulation complementary experiments. results show suitable with small but not those large Our may be useful investigating elastic-body

Determination of long-term slip rates of faults in the eastern part of Iran plateau using finite element kinematic model
Since Iran plateau is located in the Alpine-Himalayan Orogenic belt, it is recognized as a region with a high seismic risk. Thus, investigation of geodynamic activities of the faults, their slip rates and corresponding deformation fields is very important for quantification of possible seismic risk in this region. The aim of this study is to analyze the tectonic features of eastern part of Iran...
متن کاملStudy of Stone-wales Defect on Elastic Properties of Single-layer Graphene Sheets by an Atomistic based Finite Element Model
In this paper, an atomistic based finite element model is developed to investigate the influence of topological defects on mechanical properties of graphene. The general in-plane stiffness matrix of the hexagonal network structure of graphene is found. Effective elastic modulus of a carbon ring is determined from the equivalence of molecular potential energy related to stretch and angular defor...
متن کاملFinite Element Approximations of Nonlinear Elastic Waves
In this paper we study finite element methods for a class of problems of nonlinear elastodynamics. We discretize the equations in space using Galerkin methods. For the temporal discretization, the construction of our schemes is based on rational approximations of cosx and ex . We analyze semidiscrete as well as secondand fourth-order accurate in time fully discrete methods for the approximation...
متن کاملModified Fixed Grid Finite Element Method in the Analysis of 2D Linear Elastic Problems
In this paper, a modification on the fixed grid finite element method is presented and used in the solution of 2D linear elastic problems. This method uses non-boundary-fitted meshes for the numerical solution of partial differential equations. Special techniques are required to apply boundary conditions on the intersection of domain boundaries and non-boundary-fitted elements. Hence, a new met...
متن کاملFinite element analysis of elastic-plastic solids under Vickers indentation: surface deformation
Finite element modeling has been used to study the development of surface deformation during indentation with a Vickers indenter. A wide range of materials with different elastic modulus and yield stresses are examined. Results show that in a pyramidal indentation process, for a perfectly plastic material, sinking-in during loading can change to pile-up in unloading. This phenomenon depends on ...
