Damped natural frequency units
WebThe frequency of a harmonic function is the resonance frequency of the unit. This function describes sensor impulse response and its natural vibrations. It is a sum of: convolution of an impulse response of the plate and the component of describing movement of the sensor casing, damped vibrations with the resonance frequency of a sensor plate. Webwhere ω d = 1 − ξ 2 ω n is called the damped natural frequency, and A and B are determined by the initial conditions. This motion, which is oscillatory with decaying amplitude, is called underdamped vibration. In Figure 7 the dotted curves indicate the decay in the amplitude of free vibration, which is controlled by the damping ratio ξ.
