Davoud Naderi; Soheil Ganjefar; Mohamad Mosadeghzad

Volume 3, Issue 2 , March 2010

  In this research optimal reconfiguration strategy of the improved SRR reconfigurable mobile robot based on Force-Angle stability measure has been designed using Genetic algorithm. Path tracking nonlinear controller which keeps robot’s maximum stability has been designed and simulated in MATLAB. ...  Read More

2. An Analytical Study on Elastic Flange Wrinkling of Circular Plates in Deep Drawing Process

Farzad Moayyedian; Mehran Kadkhodayan

Volume 3, Issue 2 , March 2010

  Based on two-dimensional plane stress and bifurcation functional from Hill's general theory in polar coordinate the critical condition for elastic wrinkling of the flange of a circular blank ( the wave number in the flange and wrinkled area) during the deep-drawing process are obtained analyticaly to ...  Read More

3. Analytical and Numerical Investigation of the Deformation Length in Roll Forming Process of Circular Tubes

Mehdi SalmaniTehrani; Moslem Bahrami

Volume 3, Issue 2 , March 2010

  Deformation Length is one of the most important parameters in cold roll-forming process, which plays a fundamental role in determining the inter-distance between the stations and rate of deformation. Deformation length was first introduced by Bhattacharyya. He also obtained a closed-form relation for ...  Read More

4. Natural Convection in an Inclined Partitioned Enclosure with Local Heat Source

Parnian Safaei; Behzad Ghasemi; Amir Khorram

Volume 3, Issue 2 , March 2010

  In this paper, free convection in an inclined stepped chamber has been studied. One wall of this enclosure is kept cold and the opposite wall equipped with constant heat source. The remaining walls are maintained adiabatic. There is one adiabatic step on the bottom wall. The aim of the present study ...  Read More

5. Numerical Simulation of Laminar and Turbulent Mixed Convection in Rectangular Enclosure with Hot upper Moving Wall

MohammadReza Safaiy; HamidReza Goshayeshi

Volume 3, Issue 2 , March 2010

  Mixed convection is a fundamentally significant heat transfer mechanism that occurs in selection industrial and technological applications. In this study, first the laminar mixed convection inside rectangular enclosure with moving wall and Aspect Ratio=10 is modeled and then the results are compared ...  Read More

6. Influence of Element Order in Various Aspect of Evolutionary Structural Optimization

Ali GHodousian; Seyfollah Sadodin; Abbas Tabasi

Volume 3, Issue 2 , March 2010

  In recent year, the evolutionary structural optimization (ESO) method, has been applied as an effective tool for structures design. The concept of ESO method is to use the finite element  results in each iteration of process and removal of inefficient material based on These results. In this method ...  Read More

7. Finite Element Analysis of Self Destruction Mechanism in a Mechanical Controller

Kourosh Hasanpour; Mehdi Massah; Mehrdad Poursina; Mehdi Salmani

Volume 3, Issue 2 , March 2010

  In this study, dynamic behavior of a controller's Self Destruction mechanism has been simulated using 3D-FEM in Adams software and investigated. This paper has been concentrated on high acceleration controller's projectiles. This controller is mechanical and has been placed in top of the projectile. ...  Read More

8. The Main Parameters Assessment of Clod and Stone Separation from Potato Crop (Inclined Belt Type) in Potato Harvester

Hosein Mosalanejad; Hosein Mobli; Afsaneh Poursoltan

Volume 3, Issue 2 , March 2010

  Harvesting practices of potato is one of the most difficult, troublesome and sensitive stages. Potatoes enter the machine with huge amounts of clod and stones: In the meantime separation of potato some stone and clod, which are the same size as of that the potatoes, shall be confide red a major problem. ...  Read More
