Angular Natural Frequency Two Masses Axial Equations and Calculator

ωn+ = [ ( (1/2) ( ( kt1/ I1 ) + ( kt2 / I2 ) ( 1 + ( I2/I1 ) )

+ ( ( kt1 / I1 + ( kt2 / I2 ) ( 1 + I1 / I1) )2 - ( (4kt1 kt2 ) / (I1 I2 ) (1/2) ] (1/2)


ωn- = [ ( (1/2) ( ( kt1/ I1 ) + ( kt2 / I2 ) ( 1 + ( I2/I1 ) )

- ( ( kt1 / I1 + ( kt2 / I2 ) ( 1 + I1 / I1) )2 - ( (4kt1 kt2 ) / (I1 I2 ) (1/2) ] (1/2)

Where:

kt1, t2 = Torsional Stiffness of Shaft ( lb-in/rad )
I1, 2 = Rotary Mass Moment of Inertia of Mass ( lb-in-sec2 )
ωn+, n- = Angular Natural Frequency ( rad/sec )
