Abstract :
Many factors, such as environmental temperature and material elasticity, can affect the output of resistance strain gauge force transducers used in vehicle traction force measurements. A data fusion method based on radial basis function (RBF) neural network is proposed to reduce the negative effects and compensate the measurement error. A multiquadrics kernel is utilized as the kernel function for the RBF neural networks. It fuses the environmental temperature in the force measurement while realizing an accurate compensation of errors. Tests have been carried out within temperature ranging from -10deg C to 60degC and the results show that the maximum error with load 80000N is below 0.5 % after compensation while it is greater than 6 % before compensation.
