Dynamic Analysis on Buffer Shaft of CRDM Latch Assembly

This paper conducts a theoretical and experimental dynamic analysis on CRDM buffer shaft subjected to the follow current, the remanence, hydraulic buffer and the final hit during the insertion of the drive rod, and calculates the initial velocity and average hitting acceleration when the buffer is hitting with the preservation magnetic pole, to provide accurate and reliable input parameters for the design and strength check of CRDM buffer shaft.
