Question

It is a question of studying the dynamic behavior of landing gear (LG) of a F18 landing.
To simulate the behavior of the system we use the figure below. 


.(t) M plane x plane CLG (t) wheel wheel k. 'wheel wheel y(t) www


The term 'mwheel' denotes the total mass of the constituent members of the wheel. 
We want to know the displacement 'xplane(t)' of the mass 'mplane' for different scenarios.
We consider that the state of the airstrips can be represented by an entry 'y(t)' which simulates the
real geometry of the roadway. The tire is modeled by a linear wheel k and a shock absorber
wheel c.
You are asked to:
1. Establish the dynamic equations of system operation;
2. Model the detailed block diagram of the system;
3. Deduce the expression of the transfer function: H(s)= Xplane(s)/Y(s) , the initial conditions
being assumed to be zero;
