Abstract

Structural analysis was performed for a new type of shower commode wheel chair. The wheel chair structure was modeled for structural simulation, and stresses and deformation were evaluated depending on the presence of stabilizer and lateral bars used to supplement structural safety. Experiments were performed using strain gage rosettes and laser distance sensors to validate simulation results. The experiments showed that the stresses and deformation were within 10% of simulation results. The simulation showed that stabilizers and lateral bars were essential to reduce lateral deformation caused by bending of the plastic lower frame. Thus, the appropriate number of stabilizers and lateral bars needs to be determined to ensure structural safety while minimizing inconvenience in using the shower commode wheel chair.
