Abstract An important factor affecting the quality of furniture joints is the value of mounting forces. Most of the research to date described in the literature focuses mainly on the reaction of furniture joints to the static loads. However, there is a lack of knowledge about the properties of these joints under dynamic loading conditions. This study aimed to verify the research hypothesis that mounting forces in L-type furniture corner joints have a significant effect on the amount of energy absorbed during low speed impact. The reasons for the damaged joints and the effect of the material type and load schemes used were explained. Newly designed, innovative furniture fasteners and traditional eccentric fittings were examined. Fasteners were mounted in particleboards and medium density fiberboards. The corner joints were subjected to dynamic tension and compression loads. Appropriate numerical models were developed to simulate the response of joints to dynamic loads. As a result, it was demonstrated that the ability of connections to absorb energy significantly depends on the value of the mounting forces and the type of materials used. Furthermore, a positive correlation between the mounting forces and the stiffness and strength of these joints was confirmed.

L型角接缝与新型创新家具紧固件在人造板中的冲击损伤响应

摘要 影响家具接缝质量的一个重要因素是安装力的大小。迄今为止，文献中描述的大多数研究主要集中在家具接头对静载荷的反应上。然而，缺乏关于这些关节在动态载荷条件下的特性的知识。本研究旨在验证研究假设，即 L 型家具角接处的安装力对低速冲击过程中吸收的能量有显着影响。解释了接头损坏的原因以及所用材料类型和载荷方案的影响。检查了新设计的创新家具紧固件和传统的偏心配件。紧固件安装在刨花板和中密度纤维板上。角接头承受动态拉伸和压缩载荷。开发了适当的数值模型来模拟关节对动态载荷的响应。结果表明，连接吸收能量的能力在很大程度上取决于安装力的值和所用材料的类型。此外，还证实了安装力与这些接头的刚度和强度之间存在正相关关系。
