“…In the case that the suspension deflects completely, this will lessen the impact load that is passed to the chassis. [2] Nishant Varma, Ravi Ahuja, T Vijaykumar, C Kannan Issued October 2020 This paper tells that it devises to take up, hold, and discharge energy. By switching out metallic leaf springs for composite leaf springs, a significant amount of sprung and weight is typically reduced to enhance ride comfort.…”

The leaf spring's purpose is to stabilize the vehicle because it’s an essentially required element for the suspension systems and assists in supporting the entire load on the vehicle. Hence, the design and analysis of leaf springs are the main focus of this study. To that aim, the CATIA V5 software is used to construct the model, and Ansys Workbench is used to perform static structural analysis. First, the solution is verified using the analytical method and the finite element analysis for structural steel, and then the static structural analysis of structural steel and composite material (CFRP) is compared for the same design. Here, we find that the deformation and stress values of the Composite material are less than that of structural steel.

“…The results show that the load-bearing capacity of composite leaf springs is related to the laying angle and volume content of the fiber, and the type of matrix has a significant effect on the stiffness. Nishant Varma et al 10 showed that the natural frequency of composite leaf spring is 93% higher than that of leaf spring. Chavhan et al 11 prepared E-glass fiber epoxy resin composite leaf spring, and studied its mechanical properties.…”

Lightweight design of leaf springs is conducive to reducing fuel consumption and improving vehicle comfort. The weight of leaf spring can be reduced obviously by using composite material. Stiffness and damping are the key factors that affect the properties of the leaf spring. The influence of the glass fiber laying angle and volume content on the stiffness and damping of the composite leaf spring was analyzed through experiment and simulation. The results show that the stiffness and damping properties of the leaf springs are related to the fiber laying angle and the fiber volume content. When the volume content and the number of layers are constant, the stiffness shows a nonlinear decreasing relationship with the laying angle, and the damping coefficient increases linearly with the laying angle. When the laying angle and the number of layers are constant, the stiffness increases linearly with the fiber volume content; the damping coefficient has a nonlinear decreasing relationship with the fiber volume content. The type of research can provide theoretical basis and reference for the design, analysis and optimization of composite leaf spring.

“…leaf spring contributes to the vehicle to the higher load-bearing capability and capacity to absorb road vibration. In addition to absorbing vibrations, it bears lateral loads, braking torque, and engine torque [6][7][8][9].To manufacture leaf springs, IOP Publishing doi:10.1088/1757-899X/1259/1/012024 2 Composite materials are increasingly widely used to replace the conventional materials components in the vehicle industry. Automobile manufacturers' key concerns in the current situation are power efficiency and weight reduction.…”

In the current era, an automobile vehicle company’s major focus is now on conserving natural resources, reducing consumption of fuel, and reducing the weight of vehicle components. To reduce greenhouse gas emissions and fuel consumption and mitigate global warming, an electric vehicle will be a viable option. However, the EV’s main issue is the vehicle’s battery longevity. More power is necessary to drive a vehicle. The best solution to the issue is to reduce the vehicle component weight. Electric Vehicle suspension systems are another sector in which these developments are performed on a regular basis. Substantial steps are being taken to improve the vehicle ride quality. In this study, static and dynamic analysis has been carried out by finite element analysis at Ansys workbench and taken structural steel material for mono leaf spring. In composite material, carbon fiber and glass fiber have been considered as reinforcement and resin epoxy has been taken as matrix for mono leaf spring. The composite material fabrication has been accomplished layer by layer at Ansys ACP. After analysis, this study has revealed that by using composite material a magnificent amount of weight reduction has been achieved without sacrificing load-bearing capability, strength, and rigidity.
