摘 要：
Both calibration method and static decoupling algorithm were employed to analyze wheel force transducer(WFT).Firstly,the calibration procedure and extraction of sample data were presented in detail based on the self-developed hydraulic bench.Then,three decoupling methods were utilized respectively to quantify the coupling effects.The main findings are as the follows:the linearity of each main calibration channel is notable;the calculated rate of static coupling of the self-developed WFT is equal to the same-type foreign product;the least square support vector regression(LS-SVR)algorithm owns the characteristics of high regression precision,outstanding generalization and excellent algorithm stability;the method to modify the algorithm of the standard OLS-RBF NN(orthogonal least square radial-basis-function neural network)improves the regression performance significantly.
