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...

Despite numerous methods to optimise their operation and parameters, anilox rolls are subject rapid wear during use due improper cleaning processes. Therefore, regular diagnosis is needed. In this study, X-ray fluorescence (XRF) analysis based on Fe Cr was used determine the elemental compositions of raster cylinder coatings. Due layered composition roll, where Cr2O3 coating applied iron core, ...

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...

ti-6al-4v titanium alloy has great application in medicine and military industries due to its capabilities, namely high strength to weight ratio and corrosion resistance. in the current research, the effect of aging treatment on microstructure and wear behavior of ti-6al-4v titanium alloy was investigated. pin on disk wear test was applied to assess the wear behavior. specimens were first solut...

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...

In this paper, a manipulability analysis of a new parallel-type rolling mill, named ‘‘paramill,’’ in its conceptual design stage is investigated. The paramill considered uses two Stewart platforms (SPs) in opposite directions for the generation of 6 degree-offreedom motions of individual work-rolls. The objective of this new approach is to pursue an integrated control of the strip thickness, st...
