Authors, first, analyse the transient response and steady-state one using theoretical inputs developed by Fourier series and the analytical outputs when input waveform is sinusoidal or quasi-impulsive.
When the input is quasi-impulsive and the value r(= τ/T) is smaller than 0.005, it is shown that there are characteristics of input waveform and of output one .
Second, they examine the mechanism of collision theoretically and experimentally the characteristics by a Hammering Oscillation Mechanism (HOM).
Loads, impulses, and accelerations are almost in proportion to the initial heights.
On the other hand, the duration times are most in proportion to the weights.
Finally, they also examine the frequency distributions of experimental accelerations under some conditions.
They consider that the distribution reflects the dynamical properties of the experimental object. |
