I use apparent mass and accelerance to research human response and compare their graph and resonance . And explain their use place and dynamic meaning. Also I use Frequency Response Function(frf) Model in accelerance research and use the apparent mass, M(f); was calculated by dividing the cross spectral density function between the input acceleration and the force at the oor, Saf(f); by the power spectral density function of the input acceleration, Sa(f) with two models.The one degree of freedom( just structure vibration) and two degree of freedom( combine human and structure) please deeply explain the numerical method of each model with both apparent mass and accelerance. Then I take 10 subjects in experience and take two vibration magnitude 0.5 and 1.
