J. Appl. Mech 83(5), 051003 (Feb 19, 2016) (9 pages) Paper No: JAM-15-1679; doi: 10.1115/1.4032500 History: Received December 16, 2015; Revised January 12, 2016

We investigate continuous axial rotation as a mechanism for extending the reach of an elastic rod injected into a horizontal cylindrical constraint, prior to the onset of helical buckling. Our approach focuses on the development of precision desktop experiments to allow for a systematic investigation of three parameters that affect helical buckling: rod rotation speed, rod injection speed, and cylindrical constraint diameter. Within the parameter region explored, we found that the presence of axial rotation increases horizontal reach by as much as a factor of 5, when compared to the nonrotating case. In addition, we develop an experimentally validated theory that takes into account anisotropic friction and torsional effects. Our theoretical predictions are found to be in good agreement with experiments, and our results demonstrate the benefits of using axial rotation for extending reach of a rod injected into a constraining pipe.

Each data point represents an average of Ω for five full revolutions, and the error bars are the associated standard deviation.

Apparatus used to measure the transverse friction coefficient, μt. A polymeric rod (1) is inserted into a 40 cm length of borosilicate tubing (2) and connected via rod clamp (3) to a servomotor (4) which provides axial rotation. The borosilicate tubing is mounted in a rotary air bushing (5) to allow complete transmission of torque through a tubing-mounted reaction arm (6) to a laboratory scale (7) placed below the apparatus.

The transverse friction coefficient, μt, is experimentally found to be independent of the rotation speed, ω, and the rod length, l, which is inserted into the constraint. The solid and dashed horizontal lines correspond, respectively, to the average and standard deviation of all the data; μt = 0.21 ± 0.01.
