A Review on the Composite Material-Based Mano Leaf Spring using ANSYS

Abstract

The suspension system is essential for providing protection and strength to the vehicle's structure. However, the suspension system is an area of concern for manufacturers in order to reduce the load of a car by decreasing its suspension weight. Suspension system weights account for 16-21% of unsprung weight. Furthermore, automotive suspension systems constantly evolve to protect against impact loads and avoid chassis deformation and damage. The leaf spring suspension systems are critical for lowering car weight and boosting fuel efficiency and ride comfort. The advantages of leaf springs are their simple and low-cost design. However, several leaf springs are utilized in cars depending on the vehicle's gross weight. The form of a leaf spring distinguishes it from other varieties. The quantity of leaves heaped together in the parabolic and conventional leaf springs is different. Automobile manufacturers want to replace steel leaf springs with composite leaf springs to reduce weight. This is a significant step toward energy conservation, lowering the vehicle's overall fuel consumption. Therefore, this study is intended to be a comprehensive resource for designing a leaf spring using various composites. Some writers utilize software such as CAITA, Creo, etc., to design leaf springs, and ANSYS software is used to analyze leaf springs. Numerous studies have suggested composite leaf springs are superior to ordinary mono and multi-steel leaf springs in terms of weight, stress, vibration, expanding strength, exhaustion life, and riding comfort.
