SINGLE LAYER PARABOLIC LEAF SPRING PRODUCTION AND PHYSICAL VERIFICATION FOR HEAVY COMMERICAL VEHICLES

In this study, single-layered parabolic leaf spring production and physical verification has been performed for heavy commercial vehicles. In this context, the raw material, manufactured from 52CrMoV4, was formed according to the design requirements (in the case of the full load of the front arm length 925 mm, full length 1850 mm). After the forming process, martensite structure was obtained by heat treatment and shot peening was performed. Before the fatigue tests of the produced samples, strain measurements were carried out with the help of strain gauges and correlation with the analytical findings. As a result of the analytical results’ correlation based on stress measurements, fatigue tests have been carried out successfully
