Leaf spring used for vehicle to support the entire weight of vehicle, to provide passenger comfort by absorbing shocks and vibrations, to control axle damping. But steel leaf spring having higher weight (Up to 10–20% of the overall unsprung weight of the vehicle) and major Challenge is to reduce the weight of leaf spring by maintaining its properties. Hence composite material used instead of steel leaf spring as it is light in weight, its extensive properties like high strength, high stiffness, corrosion resistance, low density, high fracture and good toughness.

Abstract Leaf Springs finds vast applications in different types of mechanical systems. In spite of lot of research, spring steel leaf springs finds a lot of applications in all types of heavy vehicle. Composite leaf springs represent some application of composite materials in the field of automotive lightweight materials. However, the composite material finds limited applications in the form of mono leaf but for multi leaf in heavy vehicles, its application is rare due to certain issues including delamination. Stiffness and damping properties are the critical parameter of composite leaf sprin

Abstract: In commercial vehicles, leaf springs play a major role in designing the suspension system. Leaf springs are the most popular designs having multiple leaves in contact with each other and show hysteresis behaviour when loaded and unloaded. The leaf spring acts as a linkage for holding the axle in position and thus separate linkages are not necessary. It makes the construction of the suspension simple and strong. Because the positioning of the axle is carried out by the leaf springs, it is disadvantageous to use soft springs i.e. springs with low spring constant. Leaf springs are excel

Abstract:

Fish Car Unej (FCU) Mudskip is a car designed with a rural terrain system, especially for fishing transportation. FCU Mudskip uses leaf spring suspension at the rear to support the weight of the vehicle, that is leaning towards the rear. The load of the vehicle is inclined to the rear due to the car carrying system in the form of fish and water. This conveying system can cause leaf spring failure. Therefore, this study aims to determine the value of stress, strain and cycle on leaf springs. Ansys 18.1 software was used to obtain stress, strain, and leaf spring cycle values with a thickness of

Abstract:

Now a day the fuel efficiency and emission gas regulation of automobiles are two most important issues. To fulfil this problem many automobile industries are trying to make new vehicle which can provide high efficiency with low cost. The best way to increase the fuel efficiency is to reduce the weight of the vehicle. By Introducing better material, design optimization and better manufacturing processes, the weight reduction can be achieved. A composite material leaf spring is a very good replacement for conventional steel spring by achieving weight reduction with adequate improvement of mechan

This study has become very necessary because of the current condition of the roads in our country. The study is conducted to come out with an alternative best, cheapest, and available material for the design of leaf springs to prevent or reduce vehicle breakdown due to the breaking of the leaf spring on roads. Weight reduction is one of the main focuses of automobile manufacturers in this modern era. The objective of this study is to model and analyze a leaf spring for a light vehicle suspension system with Plain Carbon Steel (FeC), Chromium Vanadium steel (Cr-V), and Aluminum 7075-T6 as the i

Abstract:

This study describes the effects of bounce, brake, and roll behavior of a bus toward its leaf spring suspension systems. Parabolic leaf springs are designed based on vertical deflection and stress; however, loads are practically derived from various modes especially under harsh road drives or emergency braking. Parabolic leaf springs must sustain these loads without failing to ensure bus and passenger safety. In this study, the explicit nonlinear dynamic finite element (FE) method is implemented because of the complexity of experimental testing A series of load cases; namely, vertical push, wi

A first test case consists of a leaf spring, which was optimized for the use in a small car. A design method made guided by a multilevel numerical modelling is developed to evaluate the influence of the chassis-leaf spring connection on the suspension stiffness. Experimental tests showed good accordance with the numerical prediction, justifying the goodness of the spring design, in terms of both static stiffness and strength. As a second test case

Abstract 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. Consequentl

Commercial vehicles are mostly equipped with pneumatic spring elements which lead to a perfect height levelling and spring rate adjustment under different loading conditions. However, pneumatic springs are not common in light commercial vehicles where passive spring elements, e.g. single- and multi-leaf springs, are still be used. Since those vehicles are covering a wide range of different loads the spring elements frequently exhibit a progressive spring characteristic, i.e. the spring rate is adjusted under deflection as soon as the load is increased.
