Structural And Modal Analysis Of Shock Absorber Of Four Wheel Small Vehicle.

Abstract

Safety And Driving Comfort For A Car??S Driver Are Both Dependent On The Vehicle?? S Suspension System. Safety Refers To The Vehicle??S Handling And Braking Capabilities. The Comfort Of The Occupants Of A Car Correlates To Tiredness And Ability To Travel Long Distance With Minimal Annoyance. Shock Absorbers Are A Critical Part Of A Suspension System, Connecting The Vehicle To Its Wheels. Essentially Shock Absorbers Are Devices That Smooth Out An Impulse Experienced By A Vehicle, And Appropriately Dissipate Or Absorb The Kinetic Energy. Suspension Systems Consist Of Springs And Dampers, Which Tend To Limit The Performance Of A System Due To Their Physical Constraints. Suspension Systems, Comprising Of Springs And Dampers, Are Usually Designed For Passengers?? Safety, And Do Little To Improve Passenger Comfort. To Meet The Current Demands Of High Speed And Safety There Is A Need To Design And Developed Such A Shock Absorber Which Can Sustain More And More Vibrations And Also Improves The Safety. This Research Explores The Analysis Of A Shock Absorber To Providing By Controlling The Vertical Oscillation Of The Vehicle To Achieve And Enhance Occupant As Well As Driver Safety. The Study Is Conducted Starting From Design Of Different Parts Of Shock Absorbers, Where The Performance Potential Of Different Concepts In Energy Absorbing Elements Is Investigated. The Model Of The Existing And Modified Shock Absorber Is Prepared Using Catia And Solid Works Software. In The Final Phase, The Proposed Shock Absorber Concept Is Implemented In A Solid Work For Motion Analysis. In This Case Before Proceeding Through The Solid Work Analysis Of The Modified Shock Absorber Models, The Static Structural And Modal Analysis Of The Shock Absorber Assembly Is Performed At A Design Load. The Analysis Of The Existing Model In Ansys, Obtained With Different Material Are Compared With Those Of The Modified Model To Illustrate The Deformation, Stress And Energy Absorbing Properties Of The Existing One And The Proposed Concept. The Existing Shock Absorber And Modified Shock Absorber Models Analysis Results Shows At Their Applying Load 5542n And 6020n Respectively, The Total Deformation And Stress Of Existing Shock Absorber Model Is Much Greater Than The Modified Shock Absorber Model Total Deformation And Stress. Thus The Passenger??S Safety, Comfort, And For Better Driving Characteristic Of The Vehicle Can Greatly Be Enhanced By Using The Modified Shock Absorber Model.
