Mechanical Engineering Vibrations & System Analysis Assignment
Spring 2015, MENG 324 Vibration and System Dynamics
HW #8 04/30/2014 (If you finish the simulation parts, I will give you 2 extra credits for final grade)
Problem 1: The modeling equations for a system are
(a) Find the transfer function when output is x1 (hint: write the input‐output equation for x1 first)
(b) Repeat (a) when the output is x2. Comment on the similarities and dissimilarities between the
two transfer function
Problem 2:
(a) Plot the pole‐zero pattern for the transfer function
(b) What is the stability of the system?
(c) Write the general form of the zero‐input response and find the system’s input‐output
differential equation.
(d) Use the transfer function to find the zero‐state responses with the input of a unit step function.
(e) Use the transfer function to find the zero‐state responses with the input of a unit impulse
function.
(f) Construct Simulink Program and simulate the responses for (d) and (e).
