this research is carried out to design and manufacturing of lathe vibration tool and their tests. firstly, one-dimensional vibration tool is designed and made of the bending vibration mode. one-dimensional vibration tool with half piezoelectric rings is considered to excite the bending mode of tool. structure of vibration tool is designed in abaqus software about 20 khz and then is made with re...
ABAQUS can be utilized in the numerical simulation of active feedback control for the purpose of vibration suppression of structural systems. Using the example of active control of a cantilever beam, the Positive Position Feedback (PPF) control algorithm is coupled into an ABAQUS dynamical structural model with the assistance of user-defined subroutines. The transient response of the beam with ...
mechanical damagesin theprocessof harvestingandpost-harvest are the most important reason in cucurbits losses. it causes the tissue destructionand consequentfruits decay. because of difference in the mechanical strength of flesh and skin of cantaloupe, internal bruising are more usual damages with no visibility. this type of injuriesis hard to predict byanalytical methods. in this study,the mec...
The effect of various heights of high-heeled shoes on foot arch deformation: Finite element analysis
Women are interested to wear high-heeled shoes to increase their attractiveness. High-heeled shoes might create harmful effects on the musculoskeletal system. Besides earlier studies proved that the function of foot and lower extremity will change due to wearing highheeled shoes [1,2]. Because of limitations of the experimental methods, direct measurements of internal strains and stresses of th...
Analytical and numerical solutions are presented for viscoelastic lifting surfaces with piezoelectric control devices. Computational protocols in terms of spatial finite elements and temporal finite differences are formulated. ANSYS is used for mesh generation and numerical solutions are carried out in ABAQUS. Because of lack of provisions in ABAQUS for displacement dependent forces (lift), add...
A suitable piece of software is presented to connect Abaqus, a sophisticated finite element package, with Matlab, the most comprehensive program for mathematical analysis. This interface between these well-known codes not only benefits from the image processing and the integrated graph-plotting features of Matlab but also opens up new opportunities in results postprocessing, statistical analysi...
The Taurus has a MacPherson strut type of suspension in the front and rear of the car, as shown in Figure 1. The various types of joints in the suspension are modeled with connector elements. These specialized elements provide an easy and versatile way to model physical mechanisms with point-to-point connections that can exhibit complex kinematic and kinetic relationships. A list of model joint...
During product development, design engineers often have the freedom to modify a number of parameters. However, any design modification requires validation to ensure the satisfaction of requirements for all load cases. With Abaqus for CATIA V5 (AFC), nonlinear finite element technology is made available within the CATIA environment, allowing design engineers to efficiently incorporate accurate s...
Electroencephalography (EEG) is used to obtain information about the electrical activity in the brain and is routinely used to diagnose neurological abnormalities. The inverse problem in EEG refers to the procedure of locating electrical sources in the brain from the extracranial electrical field measured on the scalp. The solution of the inverse problem requires the forward calculation of the ...
The structural analyses contained in this report were carried out under the direction of the National Transportation Safety Board Modeling Group with the participation of Professor Toshio Nakamura through an external contract with the State University of New York at Stony Brook. Added resources and expertise were acquired through a subcontract with Dassault Systèmes Simulia Corporation for assi...
