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...

V-Band Clamps are manufactured using a cold roll forming process consisting of six passes which plastically deform an initially flat strip by bending to produce the band’s V-section. In this paper a new method of validating numerically predicted plastic deformation in a cold formed metal strip is presented. Tensile testing of samples of the band’s material was used to obtain a direct link betwe...

Abstract In continuous casting of steel, the strand is cooled in upper part secondary cooling zone with water sprayed by nozzles towards surface. The accumulates nip lower roll a pair, forming pool which then drains off ends roll. present work, open channel hydraulics was applied for computation height between and slab casting. differential equation describing change spatially varied flow incre...

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...

Springback and longitudinal bow are two major shape defects in gradual forming processes like chain-die roll forming. In this study, the springback of AHSS hat U profiles investigated through experiment finite element simulation. The disparity along direction signifies complex deformation during Based on simulation forming, process realized by sequential die blocks causes bending reverse-bendin...

To determine the force and energy parameters of cold roll-beating external splines, characteristics deformation zone in are analysed. The geometric dimensions position change with movement roller, contact arc, reduction very small, there is an incomplete initial stage roll-beating. A discrete analytical method for calculating unit pressure proposed, process discretized into infinite number cold...

Abstract Roll forming is a continuous manufacturing process designed for large batch sizes. In order to economically produce roll formed parts with smaller sizes, the setup times have be reduced. During setup, profile defects and especially deformation caused by release of process-inherent residual stresses, also known as end flare, counteracted. However, knowledge regarding creation stresses l...
