E. Homaei; K. Farhangdoost; M. Akbari

Volume 6, Issue 1 , Summer and Autumn 2016, Pages 1-9

http://dx.doi.org/10.22061/jcarme.2016.516

Abstract
  The aim of the study was to find the optimum combination of materials and thicknesses to provide a tough, damage resistant multi-layer system with numerical methods to restore the damaged teeth. Extended Finite Element Method (XFEM) was used to assess the critical loads for the onset of damage modes ...  Read More

M. H. Ghasemi; A. H. Korayem; S. R. Nekoo; M. H. Korayem

Volume 6, Issue 1 , Summer and Autumn 2016, Pages 11-20

http://dx.doi.org/10.22061/jcarme.2016.517

Abstract
  Recording the variation of joint angles as a feedback to the control unit is frequent in articulated arms. In this paper, magnetic sensor AS5045, which is a contactless encoder, is employed to measure joint angles of 6R robot and the performance of that is examined. The sensor has a low volume, two digital ...  Read More

3. Hydraulic anti-lock, anti-skid braking system using fuzzy controller

M. Maghroory; A. Farhadi; P. Naderi

Volume 6, Issue 1 , Summer and Autumn 2016, Pages 21-37

http://dx.doi.org/10.22061/jcarme.2016.518

Abstract
  To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have ...  Read More

4. Optimization of the injection molding process of Derlin 500 composite using ANOVA and grey relational analysis

S. Khalilpourazary; N. Payam

Volume 6, Issue 1 , Summer and Autumn 2016, Pages 39-50

http://dx.doi.org/10.22061/jcarme.2016.519

Abstract
  Warpage and shrinkage control are important factors in proving the quality of thin-wall parts in injection modeling process. In the present paper, grey relational analysis was used in order to optimize these two parameters in manufacturing plastic bush of articulated garden tractor. The material used ...  Read More

Research Paper Control
5. A new strategy for controlling wind turbines against sensor faults and wake effects to harvest more electrical energy

Seyed Vahab Shojaedini; Armin Parsiannejad

Volume 6, Issue 1 , Summer and Autumn 2016, Pages 51-64

http://dx.doi.org/10.22061/jcarme.2016.520

Abstract
  This paper describes a new method for harvesting maximum electrical energy in wind farms. In proposing technique, the stochastic process principles are applied for detecting fault measurements of sensors. On the other hand, the wind farm is modeled by using fuzzy concept. Thereby the turbines are controlled ...  Read More

6. Resonant frequency of bimorph triangular V-shaped piezoelectric cantilever energy harvester

Rouhollah Hosseini; Mohsen Hamedi

Volume 6, Issue 1 , Summer and Autumn 2016, Pages 65-73

http://dx.doi.org/10.22061/jcarme.2016.521

Abstract
  The concept of “energy harvesting” is to design smart systems to capture the ambient energy and to convert it to usable electrical power for supplying small electronics devices and sensors. The goal is to develop autonomous and self-powered devices that do not need any replacement of traditional ...  Read More

7. A truly meshless method formulation for analysis of non-Fourier heat conduction in solids

Isa Ahmadi

Volume 6, Issue 1 , Summer and Autumn 2016, Pages 75-89

http://dx.doi.org/10.22061/jcarme.2016.522

Abstract
  The non-Fourier effect in heat conduction is important in strong thermal environments and thermal shock problems. Generally, commercial FE codes are not available for analysis of non-Fourier heat conduction. In this study, a meshless formulation is presented for the analysis of the ...  Read More
