Experimental Investigations and Finite Element Modelling of the Vibratory Comportment of a Manual Wheelchair
This paper presents the comparison between the numerical results provided by the finite element model of a manual wheelchair and the vibration experiments performed on the same actual wheelchair. Two patients having different corpulence participated in this study while sitting on different types of cushions. The tests were carried out using a vibrating table with white noise as the input, in an attempt to simulate the entire vibration spectrum that the user of the chair could undergo. A numerical approach based on the finite element method has made it possible to create a numerical model of the wheelchair that can then anticipate structural problems resulting from these vibratory constraints. The objective of this work is to characterize the structure of the wheelchair as well as the vibration disturbances suffered by the user according to the daily life tasks. This first study will later allow the development of a design strategy oriented towards patient’s comfort with regard to vibrations and also to develop a new type of wheelchair using an adapted structure guaranteeing a longer material life.
