The sliding door with the retractable handrail examined in this study can be installed in hospitals and nursing facilities for helping the elderly and disabled to walk independently. This provides the prospect of restoring their declining walking abilities. In this study, wood is not used as building construction, which is common usage, but as mechanical structure. Though the strength evaluation is required, there is no clear standard for the fatigue strength of wood. Hence, this study shows the method of calculating the yield strength and fatigue limit of wood by investigating the methods of calculating allowable stresses in ASTM and AIJ, which are intended to be used for building construction. Using the result, the maximum tensile stress σ max T and the maximum compressive strength σ max C on the installation part of the handrail bar mounting plate where the risk is the highest are obtained by the finite element method (FEM). It is shown to be safe for the static strength and fatigue strength above. [ABSTRACT FROM AUTHOR] |
