Case 5: vibration measuring instrument.

1] Seismic instrument [vibrometer]

outputinput=zy=r2(1r2)2+(2ζr)2

Experimental value

R = 0 to 0.3 un damped accelerometer

R = 0.3 to 0.7 damped

R = 1 velometer

R = 3 to 7 vibrometer.

2] Velometer zy.r=r(1r2)2+(2ζr)2

zy.wwn=r1r2)2+(2ζr)2

Z.wny.w=r(1r2)2+(2ζr)2

zy=r(1r2)2+(2ζr)2

3] Accelerometer zy.r2=1(1r2)2+(2ζr)2

wn2.7w2.y=1(1r2)2+(2ζr)2

zy=1(1r2)2+(2ζr)2
