Assertion (A): For an underdamped system with damping ratio ξ, the maximum overshoot is e-ξ p /(1-ξ 2) 0.5. Reason (R): Peak time of a second order under damped system = p /ω d where ω d is frequency of damped oscillations. Both A and R are correct and R is correct explanation of A Both A and R are correct but R is not correct explanation of A
(i) Using the R-H criterion, calculate the range of values of K for the system to be stable.

Thus the equivalent viscous damping ratio is half of the loss factor, and this factor of 2 is often used when plotting flutter damping plots (see Chapter 10). An alternative way of considering hysteretic damping is to convert Equation (1.28) into the frequency domain, using the methodology employed earlier in Section 1.4.1 , so yielding the FRF ...
The amplitude A and phase d as a function of the driving frequency are and Note that the phase has the opposite sign for ω
Nov 02, 2007 · Secondly the damping "rate" requirements are different at high speed vs low speed and again for bump vs rebound. Also, my thoughts about high damping ratios on aero cars are that you have to add the aero load into the "mass". I think that once you recalculate the damping ratio with downforce you'll find a much smaller (reasonable) damping ratio.
