Design of Electromagnetic Vehicle Suspension System

Abstract

Suspension Systems Serve A Dual Purpose Contributing To The Vehicle's Road Holding/Handling And Braking For Good Active Safety And Driving Pleasure, And Keeping Vehicle Occupants Comfortable And Reasonably Well Isolated From Road Noise, Bumps, And Vibrations. The Shock Absorbers Duty Is To Absorb Or Dissipate Energy. In Conventional Suspension There Is Oil Inside The Shock Absorber Which Produces Heat And Friction During High Compression Is Exist. The Traditional Approach Is Incapable Of Improving Vehicle Control And Passenger Safety, Particularly In The Event Of A Serious Car Accident Caused By Rollover. This Thesis Has, An Objective Of Design Of Electromagnetic Vehicle Suspension System Which Replaces The Current Suspension System. To Develop The Goal Of The Thesis Theoretical Design Case And Analytical Methods Were Used. Analytical Modeling Method Were Preliminary Used To Obtain The Basic Electromagnetic Constraints Such As; Normal Force, Electromagnetic Field Density, Electromagnetic Field Strength, Length Of The Wire And Total Number Of Amperes Turns. Geometric Dimension And 3d Modeling Of The Components Has Been Defined By Using Catia Software Simulation By Ls Dyna For Existing Shock Absorber And Ansys Maxwell For Modified (Electromagnetic Shock Absorber) Software. The Driving Force That Represented The Dynamic Force Acting Of Shock Absorber When The Moving Car Meets The Bump Or During Acceleration Of Pavement Road Was Assumed F=11175 N. From The Electromagnetic Simulation Of Shock Absorber, The Dynamic Condition Of Electromagnetic Transient Type Simulation Result Has Been Generated And The Existing Shock Also Simulate. The Performance Of The Electromagnetic Shock Absorber Obtained From Simulations Was Compared With Traditional Shock Absorber. Energy Absorption Is 360j And 422.4j For Existing And Modified Shock Absorber When Compare With Analytical 1.8% And 15% Error Respectively So The Design Is Safe. Force Analysis Is 10990n And 13200n For Existing And Modified Shock Absorber When Compare With Analytical 1.6% And 18% Error Respectively So The Design Is Safe. More Force Occur On Modified Shock Absorber Therefore Electromagnetic Suspension Best.
