“…Automobile manufacturers have placed decreasing weight. Because of its advantageous strength-to-weight ratio, the automotive industry has shown interest in converting from steel springs to composite leaf springs [16].Due to composite materials' outstanding resistance to corrosion and high strength-to-weight ratio, the automobile industry is becoming more and more interested in substituting steel leaf springs with composite ones [17][18].‖Steel, the material chosen for modern leaf springs, has some disadvantages, including increased weight, increased corrosion, and increased noise. When stress is applied, the properties of the material change, leading to low natural frequency similarly for other examples [19][20].…”

Vibration-related failures more frequently occur than material failures, analysis is crucial to the design of composite leaf springs. It must also have an outstanding fatigue life and be lightweight. To minimize vertical vibrations, hits, and bumps caused by irregular roads and to ensure a comfortable ride, springs are essential suspension components in automobiles. Hence, the material with the highest strength and lowest longitudinal elastic modulus is ideal for use in leaf springs. In the automotive business nowadays, composite materials primarily replace metal elements. Consequently, it is important to use a hybrid composite leaf spring that evenly distributes graphite, carbon, and glass fibers throughout the resin matrix and has a lower spring rate. Hybrid composite materials offer many advantages over conventional composite materials because they use glass and carbon fibers instead of them. These advantages include maximum strength, minimum longitudinal modulus of elasticity, reduced weight as well as vibration, better packaging, enhanced durability, cost savings, fatigue life, and strain energy capacity. The first use of modal analysis is to determine Eigen-vectors, or mode shapes, and Eigen-values, or natural frequencies. Moreover, random vibration analysis is used to distinguish between smooth and rough vibrations, and harmonic analysis is used to determine the response’s amplitude.

“…In studies on leaf spring design to reduce vehicle weight, it is concluded that this can be achieved by using composite materials. By compiling these studies, they analyzed the problems in reducing the total weight of the vehicle by using the springs produced from the composite material and concluded that the contribution of composite springs to the weight reduction according to the steel springs is positive (Sharma and Bergaley, 2014).…”

The automotive industry has been growing steadily and paying attention to develop technologies and production processes in the world. Automotive companies are facing great competition due to the increasing number of companies and the rapid increase in customer expectations as a result of developing technological products. In order to compete, automotive manufacturers need to meet the expectations of customers and governments, such as vehicle weight, collision safety, fuel emissions and vehicle comfort. In order to ensure that competition is sustainable, companies should design lighter and more efficient parts that require less processing costs with more precise operations. Recently, concerns about fuel consumption and air pollution have been reported. Meta-heuristic optimization methods have been widely used for optimization of vehicle component over the past three decades. In this paper, differential evolution (DE) algorithm is used for optimization of the coil spring design, which is one of the suspension spring types. Using the DE algorithm, the mass of the coil spring decreased by about 29.3 %. The results show that the DE algorithm provides better solutions as previous methods in the literature.
