A Simplified model to study PORPOISING

From Simulink to simulate this spring-mass equation

From CFD Simulations

Ride Height

Porpoising Motion Analysis using SIMULINK

SIMULINK EQUIVALENT OF THE EQUATIONS USED TO MODEL THE PORPOISING MOTION

Displacement of car's body from mean position (m) vs time (s)

Porpoising starts at this point

Vibrations are damped down due to dampers(controlled by "c" damping co-efficient) used in the model
