4.1 Traditional Suspension
See Fig. 5.
4.2 Optimized Suspension
Test for transmissibility is carried out for variable vehicle speeds. Displacement in
Y-direction is measured for bump size of 10 and 3 cm. The transmissibility thus
obtained for traditional and optimized suspension is listed in Table 3. Kinetic and
potential energy is measured at handle bar. For comparison purpose, a superimposed
graph is plotted against time in Figs. 6 and 8. From above graph, it is observed
