this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

In the last few years, several DACs have appeared on the market and sold as “upsampling” DACs. Upsampling DAC manufacturers claim that their products improve the sound quality of standard CDs as compared to conventional DACs and most listeners agree. What can possibility account for the improved sound quality? After all, the digital data on the CD is the same no matter what DAC is used to conve...

In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...

the objectives in the cold rolling process include improved sheet surface quality, enhanced steel mechanical strength, and better solidification operations. given the increasing demand for higher steel surface quality, more rapid production, and thinner steel plates, more attention has been directed toward the parameter of temperature in cold rolling as a means of achieving the above objectives...
