अवधारणा:

एक द्वितीयक क्रम प्रणाली की अवमंदित प्राकृतिक आवृत्ति को निम्न द्वारा दिया जाता है

\({ω _d} = {ω _n}\sqrt {1 - {\xi ^2}} \)

जहाँ,

ωn = प्राकृतिक आवृत्ति

ζ = अवमंदन अनुपात

गणना:

दिया हुआ-

ωn = 11 rad/sec

ζ = 0.6

अब, प्राकृतिक अवमंदित आवृत्ति की गणना इस प्रकार की जा सकती है

\({ω _d} = {11}\sqrt {1 - {(0.6)^2}} \)

ωd = 11 x 0.8

ωd = 8.8 rad/sec
