ANALYSIS OF FRICTION JOINING OF PRESSED GRATING FLATS
Journal Title: Tribologia - Year 2018, Vol 278, Issue 2
Abstract
The aim of the paper is to analyse the friction forces in joints of pressed platform flat and transverse bars. Actual friction forces could have been determined based on the diagrams of force changes in the process of removal of a transverse bar from a groove in a flat bar. The paper presents diagrams of pressing and removing forces of transverse bars. The measurement of forces has been done for three distances between grooves in flat bars, i.e. 11.1 mm, 22.2 mm, and 33.3 mm. A significant variation of force values has been observed during both pressing and the extrusion of the bars. It has been assumed that one of the main causes of variation is the groove geometry. On the groove, walls there are stamp material shearing areas and breaking areas. The shearing area determines the friction force values.<br/><br/>
