Vibration Characteristics Analysis of Convalescent-Wheelchair Robots Equipped with Dynamic Absorbers
Figure 3
A comparison of the dynamic responses calculated from the vibration models of the convalescent-wheelchair with DA and without DA: (a) the wheelchair body RMS acceleration versus the running speed u; (b) the convalescent RMS acceleration versus the running speed u; (c) the TDD RMS versus the running speed u; (d) the wheelchair body acceleration PSD versus the frequency f; (e) the convalescent acceleration PSD versus the frequency f; (f) the TDD PSD versus the frequency f.
