The objective of investigations was to determine rigidity and strength of temporary joints applied in cabinet furniture. In particular, the authors intended to determine the distribution of ordinary stresses in wood, metal and plastic connections of temporary joints and in parts of boards in direct contact with these fastenings. The performed laboratory investigations and numerical calculations showed that trapezoid temporary joints with metal construction were characterised by the most advantageous rigidity-strength properties, while wood dowels in these joints were found to play a significant role supporting their strength.
Stifness modelling of semi-rigid furniture joint with eccentric connector. The aim of the presented study was to model semi-rigid furniture joint with eccentric connector. In the range of investigations was modeling particleboards in three cases, one layer, three layer and five layer. Furniture corner joint with eccentric connector was model as Hettich Rastex 15, with twister DU 644 screw-in dowel and socket number 100. Particleboard was modelled as linear orthotropic material. For modelling SolidWorks Simulation 2011 package was used. Results shown that, increasing the number of layers increases the accuracy of simulation, and the model brings to the real density profile.
