Problem Definition:
I was tasked to develop a dynamic model for the Ride Dynamics of a vehicle. I employed an 11 degrees of freedom model, which included the sprung mass vertical displacement, unsprung mass vertical displacement at all 4 tires and the yaw pitch and roll at the center of gravity. The stiffness and damping parameters of the suspension and tires were taken out of literature and checked for the trend.
INPUT:
INPUT:
The input to the model is the road profile at each individual tires. There is a small delay provided in between the road profile at the front and back tires to simulate longitudinal motion. The road profile is the data from the Smart Road at VTTI, Blacksburg.
