1. Multi-objective Suspension Optimization of a 5-DOF Vehicle Vibration Model Excited by Random Road Profile

Mohammad Hasan Shojaeefard; Abolfazl Khalkhali; Pedram Safarpour Erfani

Volume 7, Issue 1 , March 2014

Abstract
  The vehicle driving comfort has become one of the important factors of vehicle quality and receives increasing attention. In this paper, optimal points of vehicle suspension parameters are generated using modified non-dominated sorting genetic algorithm (NSGA-II) for Pareto optimization of 5-degree of ...  Read More

2. Optimal control with adaptive weighting coefficients for integrated vehicle dynamics control

naser esmaeili; S. Hamed Tabatabaei Oreh; Reza Kazemi

Volume 7, Issue 1 , March 2014

Abstract
  Abstract: In this work, an optimal control scheme with adaptive weighting coefficients is presented which coordinates different vehicle dynamics control objectives, thus ruling out possible conflicts among them. In a new approach, the weighting coefficients in optimal control are adjusted according to ...  Read More

3. Design Enhancement of EGR System for Improved Vibration Performance on Truck Diesel Engine

Karthikeyan Subramanian

Volume 7, Issue 1 , March 2014

Abstract
  In the diesel engine Exhaust Gas Recirculation (EGR) components, valve and connecting pipes are the critical components and fails often during new engine development. These components are important for meeting NOx emissions norms. Therefore design of these components should remain robust. But the challenge ...  Read More

5. Application of Different Hill’s Yield Criteria to Predict Limit Strains for Aerospace Titanium and Aluminum Sheet Alloys

Milad Janbakhsh; S. M. R. Loghmanian; Faramarz Djavanroodi

Volume 7, Issue 1 , March 2014

Abstract
  More recently, Titanium and aluminum alloys are gaining more interests to be implemented in hydro-forming applications. It is necessary to predict forming limits for these sheet alloys. Forming limits play an important role in metal forming processes. Forming limit diagrams, present the limit strains ...  Read More

6. Nonlinear vibration and instability of embedded viscose-fluid-conveying pipes using DQM

Mohammad Mehdi Ghaitani; Ali Ghorbanpour Arani; Hasan Khademizadeh

Volume 7, Issue 1 , March 2014

Abstract
  In this paper, nonlinear vibration and instability response of an embedded pipe conveying viscose fluid is investigated. The pipe is considered as a Timoshenko beam embedded on an elastic foundation which is simulated by spring constant of the Winkler-model and the shear constant of the Pasternak-model. ...  Read More

7. Design and performance evaluation of Tuned Vibration Absorber for the vibration control of a centrifugal pump

Anant Jitendrakumar Sheth

Volume 7, Issue 1 , March 2014

Abstract
  With the prolonged use of domestic centrifugal pump, due to erosion, corrosion and an unbalance the sever vibration of the pump are resulted. An erratic sound coming out of pump makes the user uncomfortable. Here, Tuned Vibration Absorber (TVA) is used as a vibration controlling device. It is designed ...  Read More

8. Process Parameters Optimization to Improve Dimensional Accuracy of Stereolithography Parts

sadegh Rahmati; Farid Ghadami

Volume 7, Issue 1 , March 2014

Abstract
  Stereolithography process limits wider applications due to low dimensional accuracy comparing with CNC. To improve accuracy and reduce part distortion, understanding the physics involved in the relationship between the setup input parameters and the part dimensional accuracy is prerequisite. In this ...  Read More
