Investigation on Effect of Vibrational Distribution and Reduction Analysis on Mercedes Benz City Bus

Abstract

The Research Examines The Impact Of Vibrations On Passenger Comfort In Mercedes Benz City Buses, Which Use Passive Suspension Systems. It Highlights The Importance Of Vibration Control For Enhancing Passenger Satisfaction And Overall Bus Performance, Particularly In Improving Health And Comfort. The Study Employs Ansys Transient Multi-Body Dynamics And Matlab Simulink To Analyze The Vibrational Dynamics Of The Bus, Comparing Existing Models With Modifications To Rubber Sealing Positions Between The Engine And Chassis, The Bus Body And Chassis, And Passenger Seats. The Results Indicate That The Full-Sealed Model (Besrc) Offers Superior Vibrational Performance, Achieving A Passenger Comfort Factor Of 8.35, Significantly Higher Than The Existing Model (Wr) At 3.07. The General Bus Comfort (Gbc) Also Showed Improvements Across Different Models, With Besrc Achieving A Score Of 7.84 Compared To Wr's 6.75. Matlab Simulations Confirmed These Findings, With A Gbc Quality Factor Of 7.3, Deviating By 8% From The Transient Analysis Results. The Study Concludes That The Besrc Model Represents A High-Quality Passive Suspension System That Effectively Enhances Both Bus Body Stability And Passenger Comfort During Operation.
