| Abstract: | This article introduced the transfer matrix method about the natural frequency calculation of the multi-degrees freedom rotor system,as well as inferential reasoning process about Prohl law and theRiccatilaw.Using formidable cartography and computation function of the Matlab as well as the good value stability about improved Riccati law,it avoided the losing of the natural frequency and enhanced the precision of entire rotor system further analyze.The value stability of various algorithms areanalyzed with Matlab in the paper too. |
