Based on the structure of automobile gear shifting manipulator,a general regression neural network is designed to measure the move contrail.It has two inputs,named a、b which stand for angle coordinates.It has two outputs,named x、y which stand for coresponding space coordinates.It adapts radius function as neuron passing function of the middle layer and line function as neuron passing function of the output layer.The smooth coefficient is tested in range between 0.05 and 0.1 and 0.05 was chosen after comparison of effect.The network is trained and simulated with part of experimental data.The validity and precision of the network model have been verified with predicting the other part of experiment data and analyzing the resulting error.The GRNN model method can be applied successfully to this measurement system.
