Question:
In order to transport sensitive equipment a crate is installed inside a truck on damped springs, as shown in Figure 11.23. The suspension system of the truck, including the tyres, may be modelled as a damped spring. The various spring and damper constants are indicated in the figure. The masses of£the crate and truck are M1 and M2 respectively and their displacements from equilibrium are respectively x1(t) and x2(t). The vertical displacement of the truck as it traverses a bumpy road may be modelled by applying a force u(t) to the truck.
Show that the motion of the crate and truck may be modelled by the differential equations
Using an appropriate software package, such as MATLAB/SIMULINK, the model developed may be used as the basis for simulation studies of various scenarios.
