Mode Transition Phenomenon of Herringbone Gear Power-split Transmission System by Jincheng Dong, Sanmin Wang

“…The mode transition will bring about the dramatical changes of the dynamics characteristics of the herringbone gear power-split transmission system， so the mode transition phenomenon must be analyzed in the process of the transmission system dynamic design. The torsional vibration model and the free torsional vibration differential equations of the herringbone gear power-split transmission system are established， and the torsional vibration models are classified to two kinds of the coupled vibration mode and the branch gear vibration model by calculating the torsional vibration natural frequency and vibration mode. …”

Research on isolated-forwarding technology oriented polymorphic network by Aihua LIU, Hanguang LUO, Jianzhong WEN, Zhiguo ZHAN

“…The polymorphic network adopted the idea of “separation of network technology system and supporting environment”, and through innovative network development paradigms, various existing or future network technology systems dynamically load and run on a fully dimensional and definable network environment in the form of network polymorph.The “self-directed and self-sustainable development” of diversified network technology systems was realized in the same physical facility.Based on the study of polymorphic network architecture, the technology of mutual isolation between network polymorphs was mainly proposed in polymorphic forwarding processing, and in the current Ethernet physical facilities, the Ethernet physical layer technology was used to realize the hard isolation function of polymorphic network forwarding, so as to achieve the effect of physical isolation of polymorphic network in the same Ethernet interface and switching medium, then provided independent forwarding environment support for network polymorph.…”
