Exploration of fatigue and modal analysis on mono leaf suspension made by natural composite materials

Abstract

Leaf Spring architecture is a major achievement in the design and production of the product in commercial vehicles. The most common designs with a multiplicity of leaves are leaf springs which display hysteresis when loaded and unloaded. The approaches often used to evaluate spring strength are time intensive and expensive, such as resilience tests on the field and rough tests. In the early stage of the design cycle, however, simulated ways to measure strength and rigidity offer useful knowledge and save time and cost. They are versatile for the assessment of various design options and for the early shift in design. In this work, mono leaf spring suspension was analyzed on the fatigue and modal with different composite made by E-Glass and natural fibers and the results are compared with the base materials steel (65Si7). The 3D modelling was carried out and analyzed with ANSYS on both a steel and a composites blade spring.
