“…However, it was compared with somewhat matching work. Birhan Alemu Tadesse and O. Fatoba Tadesse [11] worked with the Theoretical and nite element analysis (FEA) of coated composite leaf spring for heavy-duty truck application and found similar results for heavy vehicles with higher maximum equivalent stress518.29 MPa in parabolic composite leaf spring. Stress and deformation were compared with Tridedi Achyut V.…”

Leaf spring is designed to bear load as well as shocks in automotive vehicles. Two leaves of glass fibre-reinforced composite (GFRC) of various shapes sandwiched between steel plates have been analysed for application in a minitruck. Computer-aided engineering analysis was done for five different types of GFRC material leaf springs: both flat leaf, flat and parabolic leaf, both parabolic leaf, both parabolic leaf springs with aluminium alloy bush at eye-end and spring steel multi-leaf springs. A silencer pad was used in the parabolic leaf spring to reduce delamination and vibration at contact points of the mating leaf. Various shapes and combinations of leaf, provided varying parameters of deformation, maximum equivalent strain, maximum equivalent stress and fatigue life. CAE results show that the flat leaf and parabolic leaf combination provided maximum equivalent strain, maximum equivalent stress and fatigue life as compared to other cases.

“…Compared with traditional steel leaf springs, composite leaf springs (CLSs) with service cycle, sound noise reduction, strong design ability, and good safety fracture (Shamsaei and Rezaei, 2004;Kueh and Faris, 2012;Soner et al, 2012;Ke et al, 2019). It is reported that the CLS can replace the traditional steel leaf spring and have better fatigue performance (Tadesse and Fatoba, 2022a;Tadesse and Fatoba, 2022b). According to the installation mode, CLSs can be divided into horizontal and vertical springs.…”

The thermal failure mechanism of sliding composite leaf springs (SCLSs) is examined in this research. Bench fatigue testing is used in the experimental investigation of the thermal failure temperature and mode. The findings demonstrate that after 20 min, when the temperature reaches the glass transition temperature, cracks start to form around the bolt hole of the composite body. The findings from bench experiments indicate that thermal fatigue failure of SCLS can be divided into three main forms: delamination failure of the resin-rich layer, the resin-fiber interface, and fibre pull-out failure. The utilization of finite element simulation has demonstrated that when subjected to thermal load, the leaf spring’s internal defects can lead to localized stress concentration. The structure of the spring end is optimized using the insulating panel scheme and the metal joint scheme. The thermal fatigue issue with SCLS is best addressed by the heat dissipation approach, according to bench tests.
