Design and Analysis of Composite Mono Leaf Spring for Toyota LHD Hilux Double Cabin

Abstract

In This Research Project, Design And Analysis Of Leaf Spring Using Epoxy E-Glass Ud, Epoxy S Glass Ud And Epoxy Carbon Ud (395 Gpa) Prepreg Composite Materials Have Been Performed And Compared With The Conventional Steel Leaf Spring Which Is Used By Light Vehicle (Toyota Pickup). The Main Objective Of This Research Project Analysis Is To Design, Static And Dynamic Analysis Of Leaf Spring Using Epoxy E-Glass Ud, Epoxy S-Glass Ud And Epoxy Carbon Ud (395 Gpa) Prepreg Composite Material For Light Vehicle By Using Finite Element Analysis Without Changing Of The Dimension And Load Carrying Capacity Of The Existing Conventional Steel Leaf Spring. The Main Investigation Of This Project Was To Reduce Overall Weight Of The Leaf Spring With The Same Strength Of The Existing One. To Solve This Problem In This Case Composite Materials Have Play An Important Role. The 3d Modeling Of Both Conventional And Composite Mono Leaf Spring Was Done On Solid Work 2013 And Analyzed Using Ansys 19.2 Workbench Software. Analysis Results Of Stress, Weight, Natural And Harmonic Frequency Of Existing And Mono Composite Leaf Spring Was Compared. Through Analysis It Has Been Observed That Mono Composite Leaf Spring Has 35.29 % Less Stress, 2.96 % Less Deflection And 67.9 % Weight Reduction Than Conventional Leaf Spring. The Ranges Of Natural Frequency Of Composite Leaf Were 8hz-400hz. This Project Has Also Been Determined Which Material Is Best To Design Leaf Spring For Light Vehicle (Toyota Pickup). Finally In This Research Project Researcher Has Designed And Analysis The Epoxy E-Glass Ud, Epoxy S-Glass Ud And Epoxy Carbon Ud (395 Gpa) Prepreg Composite Materials Leaf Spring And Conventional Steel Leaf Spring And Compared Their Performance. It Has Been Observed That E-Glass Ud, Epoxy S-Glass Ud Composite Material Leaf Spring Has Better Performance Than The Epoxy Carbon Ud (395 Gpa) Prepreg Composite Mono Leaf Spring And Conventional Steel Leaf Spring.
