| Abstract: | The work examines the effects of frequencies of vibrations at different amplitudes on friction force, axial force transfer, and lock-up force of buckled rod constrained in a horizontal cylinder for different media under normal and high temperature environments. Studies have shown that vibrations induced in the rod have significantly reduced friction force, improved axial force transfer and deferred the initiation of critical buckling and lock-up forces for all media in normal temperature environment. Similar trends were observed at higher temperature environments; however, vibration parameters were less effective particularly on very high temperature. Results have also shown that frequency has a particular relationship with the friction force and axial force transfer and employing higher frequency would not improve the results. |
