Modeling and Analysis of Wire Rope for Transmission Line under Various Loading Conditions
International Journal for Research in Applied Science and Engineering Technology
Wire ropes are considered and applied to industrial applications that includes mining, off-shore oil production, and towing or mooring ships. Wire ropes are also used extensively in such diverse transportation applications as ski-lifts, cable cars, bridges, cranes and elevators. Premature failure of ropes can be costly in any application. In mining, the human costs due to the premature failure of a rope can be devastating. The wire rope considered in present research is IS 398, ACSR Conductor,
... 8, ACSR Conductor, Theoretical calculations are performed to calculate sag and slack for the rope. Distance between poles is taken as considered 30480mm. Thermal elongation with temperature variation is calculated and also simulated and analyzed with ANSYS design software. Aeolian vibration frequency is calculated to obtain frequencies with different wind speed, Software results for frequencies are found similar to theoretically calculated results. Experimental analysis is performed in IIT Indore to conduct tensile. It is found that breaking load is approximately 28KN and software simulation results for tensile test are approx. 30KN. Present research ultimately tried to focus on the modeling and analysis of wire rope for transmission lines considering the pole distance and sag of the wire rope, further comparing the simulated results with the theoretical, and trying to make a common set up for the test and validation of results experimentally.
