| Abstract | This experimental research involved the fabrication and development of aprototype to determine rail parallelity; the prototype is mobile in nature andcan easily change the point at which measurements are to be made. Parallelityof BS100A standard rails, with a parallel distance of 459 mm, was measuredusing the developed hydraulic parallel gauge (HPG) along with a pressuretransducer. Experimental results were validated with those obtained using alaser distance meter; the measurement accuracy was noted to be 0.89 mmor 11.13 percent difference. The fluctuation of the internal pressure of thehydraulic cylinder, which was due to the accumulation of the stored pressureduring the change of pressure, was the source of error. Such a fluctuation cannevertheless be reduced by using a spring with higher stiffness value. Basedon the experimental data, the relation between HPG pressure and paralleldistance could be correlated using a fifth order polynomial equation. Themobile HPG developed in this research can be further developed and usedwith the standard gauge rail system after being calibrated with a standardmeasurement device viz. a track gauge meter. This would result in thedevelopment of HPG into practical use in rail parallelity measurement. |
