The purpose of this program is to perform modal analysis for a two-degrees of freedom tractor suspension system. Galerkin's method over "ne" individual elements of time domain [t1,t2], was used to numerically solve the two uncoupled resulting 2nd-oder ODEs.
Original suspension model:
xs(t1 )=xs1 , xs(t2 )=xs2,
xw(t1 )=xw1 , xw (t2)=xw2
Boundary conditions in modal coordinates:
The output of this program:
1- The solution of Etta1(t), Etta1'(t), Etta1"(t)
2- The solution of Etta2(t), Etta2'(t), Etta2"(t)
