Wood–wood friction is an ancient subject, and its related mechanisms have been elucidated. However, the tribological mechanism of wood–wood friction at a high speed is still unclear. In this paper, an experimental equipment of wood friction welding was designed and fabricated. The influences of welding equipment and wood parameters on frictional force, normal force, and welding interface temperature were studied. Results show that the speed of welding into wood has a significant effect on interfacial force and normal force. Increase in wood moisture content reduces frictional and normal forces, and increase in fiber angle increases frictional force, normal force, and welding interface temperature. This study provides theoretical and technical basis for the study of wood friction welding.

木木摩擦是一门古老的学科，其相关机制已被阐明。然而，木-木高速摩擦的摩擦学机制仍不清楚。本文设计并制作了一种木材摩擦焊实验装置。研究了焊接设备和木材参数对摩擦力、法向力和焊接界面温度的影响。结果表明，焊接到木材中的速度对界面力和法向力有显着影响。木材含水量的增加会降低摩擦力和法向力，而纤维角度的增加会增加摩擦力、法向力和焊接界面温度。该研究为木材摩擦焊的研究提供了理论和技术依据。
