Question


I am attempting to set up a model for a suspension on a mass of 100kg with k=17kN/M and a damping ratio of 0.5. The system is modelled as a simple spring damper system.
The model below is attempting to model a base excited spring damper system. I feel like the issue is that the initial sinusoidal...

Question


I need to find the displacement and velocity characteristics of a suspended mass on a boat. I am struggling to develop a state space expression that can take a sinusoidal input, and then to plot graphs of displacement and velocity from this.
clear t=0:0.1:10; %time peroid Y0= input('wave amplitude ') ; ...
