Figures & Tables

Figure 1

The model of the system.

Figure 2

Deflection of the structure. An absorber with parameters μ=0.05, κ=1.

Figure 3

Deflection of the structure without an absorber.

Figure 4

Deflection of the structure in the midspan for two absorbers with different κ.

Figure 5

Deflection of the structure in the midspan for two absorbers with different μ.

Figure 6

Deflection of the structure without an absorber in the middle of the beam for three velocities.

Figure 7

Deflection of the structure with the absorber μ=0.05, κ=1 in the middle of the beam for three velocities.

Figure 8

The expected value of deflections in the midspan for different vehicle velocities and also for (a) different parameters μ of the absorbers and (b) different parameters κ of the absorbers.

Figure 9

The variance of deflections in the midspan for different vehicle velocities, and also for (a) different parameters μ of the absorbers and (b) different parameters κ of the absorbers.

Figure 10

Deflections in the midspan for different locations of the absorber: (a) the expected value and (b) the variance.
