PROJECT 7: Matlab Programming
Solution of 2 dof homogeneous system
Problem Statement
1.Solve the 2 degree of freedom problem for the unforced motion of the
system of Project 7, for the following initial conditions:
-
both initial velocities = 0
-
lower displacement = 1 ft
-
m1=1;
-
m2=9
-
k1= 1;
-
k2= 1;
-
c1= .2;
-
c2= .2 ;
Suggest using
-
function B=solver(t)
-
A=amatrix;
[V,D]=eig(A*t); B=V*diag(exp(diag(D*t)))*inv(V);
or
B=expm(A*t);
to obtain a solution
2. Calculate & plot the response curves.
Submit
standard report including:
-
source codes
-
input files
-
printout of the pertinent matrices
-
2 plots of the solutions, displacements on one plot, velocities on the
other. Use a time span of 50 seconds
.
