Carries on the planetary transmission dynamics analysis using the finite element Based on elastic theory, in order to simplify the solution of the problem, the establishment of a finite element model,the following assumptions were done: first gear materials isotropic; second gear materials is a continuous, uniform; three is ignored when the gear tooth surface friction on[2]. 2.1 Create geometric model Gear parameter as shown in Table 2-1, planetary transmission full-scale mockup as shown in Figure 2-1.

The same accuracy requirement applies to material properties.
All methods rely on the material properties derived from experiments or material design criterion.
In the simplest case, fatigue properties for a smooth parent material subjected to fully reversed loading are available.
Carbody structure is subjected to random loading, which can be very difficult to correlate to constant amplitude material properties.

It is found that flap-twist coupling effect is only related to the laminated materials, not sensitive to the geometry shape.
Based on the previous study [5], the bend-twist coupling parameter is analyzed first in this paper, then the coupling effect is proved to be only related to the laminated materials by carrying out the spar cap of bend-twist coupling design.
The reason is that the transverse modulus of carbon fiber is similar to that of the glass fiber, there is no much difference in twist stiffness between two materials.
