In view of the residual velocity of inspection mass release of the spatial inertial sensor,a prediction method based on Kriging surrogate model is proposed.The Kriging surrogate model,RBF surrogate model and SVM surrogate model are respectively applied for test data fitting,and the correlation coefficient R is adopted as the indicator of model accuracy for evaluation of these 3 kinds of surrogate models.Through comparison,it is found that the Kriging surrogate model has the highest prediction accuracy for residual velocity of inspection mass release of the grabbing positioning and release mechanism.
