The onboard monitoring of the wheel-rail forces of heavy-haul freight cars is critical to the derailment evaluation due to in-train stability issues. In this paper, a wheel-rail force indirect measurement method is proposed based on the transfer characteristics of wheel-rail force and strain testing technology. Experimental and simulation results show that this wheel-rail force indirect test method has high identification accuracy, greatly reduces the test cost and the method is suitable for long-term safety monitoring of long and heavy load freight train.
