THE SYSTEMS APPROACH TO CONTROL AND INSTRUMENTATION 2
Figure 2.10
Graph of Force Transmitted by the Tire
Figure 2.11. In this illustration, four separate responses are shown for four
different shock absorber damping constants. For very low damping coefficient
D (weak damping or defective shock absorber), the response becomes very large
for frequencies near the resonant frequency (i.e., f ):
o
M u
f = -------
o
K
This situation is depicted by the uppermost dotted curve in Figure 2.11.
For a somewhat larger damping, the response is large enough near resonance
to absorb the road force, transmitting relatively little of this force to the car body.
