The nonlocal effect is studied for a functionally graded (FG) nanobeam, which is widely used in the Nanoelectromechanical system. First, the higher-order deformation mode is introduced in terms of the generalized displacements defined for the cross section. Generalized stresses and strains are accordingly defined and uncoupled constitutive relations are derived by combining the nonlocal elasticity theory. Next, according to the principle of virtual work, an uncoupled beam theory is established for a FG nanobeam, including governing equations and boundary conditions. The current work shows that, due to the decoupling of bending, tension and higher-order bending, the nonlocal effect can be attributed to the superimposition of equivalent initial generalized stresses. Typical FG nanobeam problems are analytically solved. It is found that the nonlocal effect on the deflection of FG nanobeam is case dependent for different boundary constraints.

Reflector control technology in space laser communication

Meilin Xie, Caiwen Ma, Cheng Yao, Wei Huang, Xuezheng Lian, Xubin Feng, Feng Jing

Proceedings Volume 10605, 106050Z (2017) https://doi.org/10.1117/12.2286414

KEYWORDS: Reflectors, Aerospace engineering, Laser communications, Laser applications

The optical frequencies band is used as information carrier to realize laser communication between two low-orbit micro-satellites in space which equipped with inter-satellite laser communication terminals, optical switches, space routers and other payload. The laser communication terminal adopts a two-dimensional turntable with a single mirror structure. In this paper, the perturbation model of satellite platform is established in this paper. The relationship between the coupling and coordinate transformation of satellite disturbance is analyzed and the laser pointing vector is deduced. Using the tracking differentiator to speed up the circular grating angle information constitute speed loop feedback, which avoids the problem of error amplification caused by the high frequency of the conventional difference algorithm. Finally, the suppression ability of the satellite platform disturbance and the tracking accuracy of the tracking system are simulated and analyzed. The results show that the tracking accuracy of the whole system is 10μrad in the case of satellite vibration, which provides the basis for the optimization of the performance of the space-borne laser communication control system.
