Abstract: The nonlinear dynamic model of a gear-shaft-housing system is established by using finite element method FEM. The nonlinear dynamic response of the coupling system under gear tooth time-varying stiffness, manufacturing error and other internal excitations is analyzed.
Displacement, velocity and acceleration response of the coupling system and meshing stiffness and bearing support stiffness influences on vibration response of the coupling system are studied. The results show that the vibration amplitude near housing bearing seat is largest, secondly is the top of the housing and the vibration response at the sides and bottom of the housing are the smallest.
As meshing stiffness and bearing support stiffness increase, vibration velocity and acceleration of the housing increase gradually. But bearing stiffness influence on the vibration response of the coupling system is significantly larger than that of meshing stiffness. Abstract: This paper studies coupling between localized surface plasmons in metal nanoparticle waveguides of different materials and sizes, and then discusses another nanostructure, nanoshells, that support localized plasmons, and closes with conclusions in a variety of situations.

Abstract: Brushless electric excitation synchronous machine is a new kind of AC machine. There are two sets of windings with different pole numbers on the stator. It eliminates the brushes and slip rings.
The air gap magnetic density of brushless electric excitation synchronous machine is achieved based on Ansoft. And the influence of stator windings with different pole numbers on coupling capability is analyzed.

Optical Properties and Band Structure of Semiconductors
Published by Butterworth About this Item: Butterworth, Published by Cambridge University Press, Cambridge Making an inventory of my research, I think that my most significant works are related to the broadening of the working frequency of semiconductor devices from 10 to 10 GHz. Experimental studies and measurement techniques related to electron heating in microwave frequency 10 GHz electric fields. New phenomena caused by hot electron heating: thermo and photo electromotive force, emission, current fluctuations, generation and recombination of carriers, non-linear conductivity, negative absolute resistance, non-inertial current saturation and impact ionization in high electric fields [1—4].
