Comfort Improvement of a Pick Up Truck via Partially Mounted Differential Suspension

The comfort of the passengers during normal vehicle ride can be affected depending on the speed of the vehicle and road profile, yet the control of the vehicle is also compromised if the parts in motion deliver high amounts of energy. This document discusses the improvement made on a pick up truck that shows questionable ride and poor control when driving over soft and rough roads at several speeds. A different rear suspension proposal helped to alleviate the problem partially via kinetic energy reduction on a rear live axle. Further tuning opportunities were detected as a result of Subjective/Objective assessments and modeling.
