Vehicle Suspension Analysis
Through Northwestern’s Vehicle Dynamics and Design course, I developed and applied a MATLAB program to perform an analysis of a suspension system, primarily focused on determining the roll center, swing arm lengths, and camber angles as the sprung mass rotates incrementally.
Equation Derivations
Example Application
Consider initial pin locations (in meters):
Left Suspension: x1 = 0.2; y1 = 0.2; x2 = 0.15; y2 = 0.35; x3 = 0.5; y3 = 0.4; x4 = 0.45; y4 = 0.42
Right Suspension: x5 = 1.3; y5 = 0.4; x6 = 1.6; y6 = 0.2; x7 = 1.65; y7 = 0.35; x8 = 1.35; y8 = 0.42
The graph displays the suspension’s original position and the same suspension after a 4 degree counterclockwise rotation of the sprung mass.
The roll center is located at (0.6556, 0.6384).
The camber angle after a 4 degree counterclockwise rotation is 1.9606.
