The wheel-rail contact forces measurement system used to measure the railway vehicle’s derailment criteria still comes from China. This measurement system is an opportunity to start the wheel-rail contact forces measurement system in Indonesia. The objective of this study is to design the wheel-rail contact forces measurement method based on wheel strain. This study expected to be a starting point in design a wheel-rail contact forces measurement system. The wheel modeling in this study utilizing SolidWorks 2020 software, based on previous field observation and standards. The wheel finite element model and static load simulation were conducted using ANSYS software. The simulation results were then used to determine the strain measurement points on the wheel web. After the strain measurement points were determined, the calibration matrix can be constructed using strain data from various static load simulations. The calibration matrix then got tested to determine the calculation error for each parameter that has been measured. In this final project, the wheel strain characteristic due to static load has been analyzed. An optimal strain measuring points including the strain gauges configuration on the wheel web and Wheatstone Bridge has been determined. The calibration matrix also constructed successfully with the calculation error for each contact force is under 1%.
