[Abstract]:In order to solve the problem of temperature drift caused by temperature change in the working process of strain gauge pin shaft sensor, a temperature compensation model of Drosophila algorithm for optimizing RBF neural network is proposed. The expanded parameters of neural network are optimized globally by Drosophila algorithm, and the temperature compensation model is trained by using the measured parameters of stress test platform and the nonlinear mapping ability of neural network. In order to verify the compensation effect and training efficiency of the temperature compensation model, the sensor was tested at 35 鈩，
