1. Flow Balance of an Extrusion Die for Production of a U-Shaped Profile

Abbas Zolfaghari; Amihosein Behravesh

Volume 2, Issue 4 , September 2009

  The main objective of an extrusion die is flow balancing as an unbalanced flow causes a distorted product together with residual stress. In this paper a strategy is presented for flow balancing a U-shaped profile with different wall thicknesses. For this purpose, a choker bar is provided at thicker wall ...  Read More

2. Investigation of Process Parameters, Gate Position and its Shape Effect on Dimensional Accuracy of Injected Plastic Part

Payman Shahi; AmirHosein Behravesh; Behrouz Arezou; Mehdi Mahmoudi

Volume 2, Issue 4 , September 2009

  Injection molding is the most widely used process for producing plastic parts.In this process, an important issue is to predict and optimize the warpage before manufacturing. In this paper, a simulation with MOLDFLOW software is proposed to optimize the injection molding process. The optimization process ...  Read More

MohamadHosein Navidfar; Saeed Ziyaee Rad; Mohamad Esfahanian; Amir Khorram

Volume 2, Issue 4 , September 2009

  In this paper the interior noise level of a vehicle due to structural vibration, named structure borne noise, as a part of NVH analysis has been investigated. First structural analysis is performed and vibrational behavior of structure carried out due to power plant excitations. Then interior acoustic ...  Read More

4. Laboratory Investigation of Austenitic Stress Relieved Spring

Yaser Moghani; Crus Aghanajafi; Mehdi Ahmadi

Volume 2, Issue 4 , September 2009

  Springs are the  mechanical parts which have many application in industries. Static and dynamic forces cause relaxation in these parts so that they lose some of their free length and reaction force. Springs constant are very important in airplane and vailway industry since constant and variable ...  Read More

5. Multi Purpose Optimization for Design of Circular Hydrostatic Axial Bearings Using Genetic Algorithm

Mohsen Dashti; Asghar Dashti

Volume 2, Issue 4 , September 2009

  In this paper, a multi purpose function is presented for optimum design in circular hydrostatic axial bearings. One or more parameters that are directly or indirectly dependent on given data are optimized. Usually in the local optimization methods, it is not possible to optimize several parameters simultaneously. ...  Read More
