Numerical method for optimizing design variables of carbon-fiber-reinforced epoxy composite coil springs

A Review: Fiber Reinforced Polymer Composite Helical Springs

“…Especially, these parameters are very important issues to design of springs in automotive industry. Related researches show that FRP composite springs are provide ideal characteristics for this aim [1,12,14].…”

“…According to obtained data's of their research study, the estimated shear modulus was in good agreement with their experimental results. Their research shows that coil spring made of CFRP is provide weight reduction about 55% than that of steel [12].…”

“…Nowadays, FRP composite helical spring is attracted the interest of many researchers but there is limited research on it. [12] Literature Survey Choi B.L and Choi B.H investigated on carbon fiber reinforced epoxy composite coil springs considering the static spring rate. In their research study, CFRP coil spring manufactured using the resin transfer molding (RTM) process, as shown in Figure 1.…”

“…Elyaf takviyeli kompozit malzemeden yapılmış yayların kuvvet-şekil değiştirme ilişkisinde G kayma modülü yerine eşdeğer kayma modülü kullanılarak Eş. 11 ile hesaplama yapılabilir [6].…”

Coil Spring for Torque Reduction in Tractor Foldable Rops

“…In order to design the coil torsion springs an electronic spreadsheet model created from equations 4, 5, 6, 7, 8, and 9 was implemented. These equations are adaptations of HOOKE's law (1678) and were also used by several authors (Pöllänen & Martikka, 2010;Choi & Choi, 2015;Yıldırım, 2016) when studying the behavior of torsion springs in a wild variety of applications. The model was solved with the help of Solver (Excel ™ Add-in) software package, mentioned by a number of authors (Dasgupta, 2008;Arif et al, 2012;Ishizu & Yamada, 2017) as a great auxiliary tool for optimizing nonlinear problems involving multiple variables.…”
