【Abstract】 To address the low efficiency and unstable quality issues of the existing grinding methods for fuel assembly springs, a flexible force-controlled grinding technique for fuel assembly springs based on a BP-PID control strategy is investigated, aimed at enhancing the stability of the grinding process and the grinding quality. The effectiveness and superiority of the method in improving grinding accuracy, efficiency and quality are demonstrated through simulation and experimental verification. The results indicate that compared with the traditional PID control, the accuracy of the BP-PID-based control strategy is increased by 10.53% and 15.97%, respectively, and the actual grinding efficiency is also improved by 97.99% on average. This research provides new technical support for high-precision surface treatment of fuel assembly springs, and also demonstrates the potential for further promotion of automated grinding technology in this field.更多还原
