STRAIN GAUGING OF ALUMINIUM HOPPER WAGONS

The development of quite serious and unexpected fatigue cracks in a number of aluminum hopper wagons, hauling coal in Central Queensland, led Queensland Railways to a program of investigation in an attempt to define the operating stresses which were affecting the structural integrity of the vehicle. The vehicle is of a complex design and difficult to analyze on paper, and it appeared that the stresses may have been higher in some regions than would be predicted. Practical stress analysis using strain gaging to define the service stresses imposed on the vehicle is presented.
