Question
The damped harmonic oscillator system
satisfies the equation mx + rx+ sx = 0.
mž +rx +
note: pay attention to the x
The displacement experienced by mass m
can be expressed by x = Ae^-rt/2m cos(w't
+ Ø ). At t = 0, the mass is at x = x0
velocity x (with one point) = v0. On this
system it is known that
wi – w² = 10-6wž.
a. If damping is removed, the mass will
ocillate in simple harmonic motion.
Determine A and Ø in the parameters xo,
vo and wo (the natural frequency of the
oscillator).
b. For this damped harmonic oscillator,
determine A and Ø in the parameters xo,
vo and w'.
c. Calculate the logarithmic reduction
9/11
and quality factor Q.
d. If w, = 10^6 rad/s and m = 10^-10kg,
calculate the spring constant s and =
coefficient r.
