Design, Modeling and Simulation of a Reconfigurable Wheelchair with Stand-sit-sleep Facilities

[摘要] Standing feature of the wheelchair allows the disabled to be able to reach different heights and thus gives enhanced navigations in different conditions. Wheelchair with back seat adjustment helps in health preservation as well as daily living activities including trunk positioning, functional enhancement stability and gait balance. Thus, paper presents the design, modeling and simulation of a reconfigurable wheelchair with stand-sit-sleep facilities. Key areas focused on maximizing safety, optimizing the size with minimizing cost and weight of the newly designed wheelchair. The contribution of paper are (i) Kinematic concept of the reconfigurable wheelchair (ii) Synthesis of the proposed wheelchair mechanism (iii) CAD modeling using the Top down modeling approach (iv) Multi-body dynamics Simulation and stress simulation of model. Wheelchair design has been analyzed and verified by using MSC ADAMS and ANSYS simulation tools. The developed model will help in improving the functional capabilities of wheelchair users allowing enhanced independence and quality of life (QoL).
