Stiffness coefficient K which can be selected according to reference[4] depends on the material and structure of contact objects
(2) Where，， The equivalent radius of two gear contact points, are the ratios of the two gears, respectively, are the Young's modulus of the materials of the two gears.
Select the material of the gear 20Cr2Ni4A, its Poisson's ratio is, the Young's modulus is.

According to the material parameters of PVB interlayer, combining with the load capacity tests, a finite element model is established to simulate the tests.
So 3-D solid element solid45 is used to model, which is defined by eight nodes and the orthotropic material properties[4].
Tab.1 Parameters of material mechanical properties Properties Material Elastic modulus （MPa） Shear modulus （MPa） Glass 0.72e5 0.295e5 PVB interlayer 1.31 0.45 In the calculation model, the dimension of glass panel is 1500mm×1500mm with the thickness of 6mm+1.14/2.28mmPVB+6mm.

In this paper, we develop a model for surrounding gate single material TFET with circular cross section view for surface potential using 2-D Poisons equation with parabolic approximation method [26].
The silicon material is considered hence, E2avg is used in Drain Current as done in [27].
The surface potential is reliant on characteristic length of cylindrical gate and gate material work function.

In addition, materials as we know rarely use LCEs in the state identification in the background of strong noise [6]. 2) Current research using the Duffing oscillator for the weak signal detection mainly concentrates on the low frequency case about 1Hz.
