Evaluation of the Factors Affecting Opening-Closing Performance of Wooden Cabinet Doors

Abstract

This study determined the deflection performance of wooden cabinet doors during opening and closing by using different material types, opening-closing angle, and load force. The independent variables consisted of material type, opening-closing angle, and load force, and the dependent variable was determined as deflection value. Medium density fiberboard (MDF) and particleboard (PB), both melamine faced, were used as two different material types. Opening and closing angles and directions of forces were performed as directed in BS EN 16122 (2012) and TSE EN 9215 (2005) and the doors were loaded by forces of 300N, 375N and 450N. The factors affecting deflection value and the interaction between them were investigated by multivariate analysis of variance. The results showed that the material type, angle, load force, and the mean between the material type and load force was significant. As the loading force increased, the deflection value increased. As the moisture increased, the deflection value increased, and as the material density increased, deflection value decreased. The adequacy of models was evaluated by the R-square (R²) and Adjusted R-square (Adj-R2) values. The results for these values were 88.23 % and 86.58 %, respectively.
