Q5: Fig. Q5 is a simplified model of car (Quarter car model). It is assumed that (1) the vehicle is constrained to one degree of freedom in the vertical direction, (2) the spring constant of the tires is infinite, that is, the road roughness is transmitted directly to the suspension system of the vehicle, and (3) the tires do not leave the road surface. Assume a trailer has 1,o00 kg mass fully loaded and 250 kg empty. The spring of...
The single degree of freedom model of a vehicle shown below will
be used to obtain a first
approximation of the dynamic behavior of the entire vehicle. The
mass m of the vehicle is
1200 kg when fully loaded and 400 kg when empty. The spring
constant k is 400 kN/m and
the damping ratio ζf is 0.4 when the vehicle is fully
loaded. The vehicle is traveling at 100
km/h over a road whose surface has a sinusoidally varying...
