Homework 02
ANSYS:
Problem 1: (The system in Homework 01C- Problem 5)
Problem 1: m1=5.8 kg, m2=3.2 kg, k1=4325 N/m, k2=3850 N/m, k3=3500 N/m, c1=37.2 Ns/m, c2=33.5 Ns/m, c3=32 Ns/m.
m2
f2 x2
k3 c3
m1
f1 x1
k2 c2
k1 c1
In the system as shown in the figure, f1 and f2 are the inputs, x1 and x2 generalized coordinates. Find undamped natural frequencies of the system by ANSYS in Hz. In Homework 01C- Problem 5, the mathematical model is established by using Lagrange equation and the following results are found by MATLAB.
f1=4.6549 Hz, f2=8.4979 Hz
Compare the results with the results found by ANSYS.
