The chassis and rear swingarm are made out of high-grade,high-tensile 25CrMo4 steel.The tubes are CNC bent and cut while the sheet-metal parts are CNC laser-cut.All parts are welded on a custom-made jig in order to assure quality and tight tolerances.All the stressed-parts are FEM analyzed and stress-tested on benches.
·Web view2 Faculty of Mechanical Engineering and Computing,University of Mostar,Bosnia and Herzegovina.E-mail [email protected] In laser welding and material 25CrMo4,the maximal hardness values range from 509 HV2 to 562 HV2,and in material 42CrMo4 they range from 679 HV2 to 694 HV2.In both welding procedures lower hardness values were obtained
