VAN ZYL, P.J.A.; BURGER, N.D.L.  and  DE WET, P.R.. Verification of a Finite Element Model of a Rotating Tippler Structure by Means of Strain Gauge Measurements. R&D j. (Matieland, Online) [online]. 2006, vol.22, pp.3-15. ISSN 2309-8988.

The complex rotational working of a tippler structure complicates the analytical evaluation of the structure. A further complication is the ever-changing boundary conditions while the structure rotates, together with the weight reduction of the coal in the wagons when the wagons are offloaded. Both these factors need to be taken into account when determining the stress levels in the structure while operational. To verify the accuracy of a finite element simulation of a tipping cycle, strain gauge measurements obtained from the actual tippler structure was compared with stress results obtained from linear static finite element analyses of the structure, simulating different tip positions at set time intervals. The results obtained from the comparison indicated an accurate simulation of the tipping cycle by means of the finite element simulation.
