Abstract:

The energy decomposing profiles used in cars and placed on the tampon are connective elements with the ability to deform the kinetic energy arising from the front and the back in collapse accidents. The failure of energy disruptor profiles to dissolve the impact forces they are exposed at an instant accident will lead to the transfer of these forces directly to the passenger section within the vehicle. The work was carried out in the framework of the fourth and circular cutting with different geometric characteristics of ten energy disconnector designs and the energy disconnector performance under loads in different angles was studied by the method of final elements. Energy deforming profiles have been deformed for 120 mm with a rough plate with angles of 0°, 15° and 30°. With the analyses made, the specific energy decomposition and decomposition power efficiency values for each energy decomposition profile have been studied. According to the results obtained, it has been found that in all cases, circular cut energy disruptors provide higher performance.
