In the literature, some studies apply the impulse excitation technique to characterize the elastic properties of isotropic materials [7], although the ASTM E1876-21 standard also applies it to anisotropic materials [6].
Halpin-Tsai materials may be transversely isotropic, orthotropic, or isotropic, depending on the geometry of the material reinforcing the matrix [10].

The steady-state operating heat conduction equation, which is resulted from the heat transfer theory, in direct-angle coordinates[4] is shown in the following (1) where T is the stator temperature in ℃. λx, λy and λz the material thermal conductivity in the x,y and z directions respectively, W/(m·K). qv the heart source density in W/m3. 2.3 Heat source in losses A number of the synchronous machine losses are the heat source[5] that results in the synchronous machine temperature rise.
(3) The thermal properties of all insulated materials are considered to be identical

Test principle of sensitivity The rate of material resistance is determined by (1) Where is the rate of resistivity.When the silicon crystal axis has a deviation with cubic crystal axes, the rate of resistance is expressed as (2) Where πl denotes longitudinal piezoresistance coefficient; πt denotes transverse piezoresistive coefficient; σl denotes longitudinal stress; σt denotes transversal stress[2]
Conclusion In order to improve the sensitivity of the sensor, the structure can be innovated and optimized,in addition to using high strain coefficient materials.In this paper, three different placement of varistor are designed, modeling and simulation are conducted by Ansys software, and the sensitive axial and transverse sensitivity are analysised and evaluated in Matlab software.The results show that the placement along with the direction parallel to the cantilever beam can inhibited the transverse sensitivity greatly, simultaneously the sensitivity of the sensitive axis is very high.
