Air-bearing is a core component of air-bearing rotary stage. The weakness that the air-bearing has the low load capacity and stiffness has been concerned about by domestic and foreign scholars. So how to improve the load capacity and stiffness has become a serious problem. In order to improve the load capacity and stiffness of the air-bearing rotary stage
in this paper
we improved structure of Zhang Wenjie and others' high-precision direct-drive air-bearing rotary stage. The gas film of air-bearing has been meshed by GAMBIT software
and we use FLUENT software to obtain the carrying capacity features of the gas film. Finally
the structural static force of the precision air-bearing rotary stage will be analyzed by ANSYS software. The analysis results show that: the structural design of the precision air-bearing rotary stage is reasonable
and this structure can provide a larger range of loads. Even in heavy load conditions
a larger deformation will not occur any more. It has a good practical value
and also can be widely used in high precision equipments. (2012) Trans Tech Publications.

Space membrane reflector is very promised for optical quality application with the merits of ultra-lightweight and flexible. In order to improve the surface precision of membrane reflectors
the formation and surface shape error of a membrane at uniform load are studied based on the henky-cambell equations of circular membrane. The ANSYS software is used to build an optimization model of membrane reflector surface shape
in which the yield strength is the state variable
the surface load on ten concentric annular regions of the mirror is the design variable
and the minimum RMS between ideal surface and mirror surface is the target function. and the theoretical and experimental result show that RMS and PV of the optimized surfaces are reduced respectively than those before optimization. In a word
this paper offers the theoretical and experimental basis of the polyimide membrane reflector. 2011 IEEE.

Studied the transient thermal transfer analysis method due to a kind of supersonic ellipsoidal dome
which is a conformal dome. Illuminated the principle of transient thermal transfer analysis. Accomplished the transient thermal analysis based on the model of ellipsoidal dome
and studied the influence about the different material and the different velocity. Considered three materials consist of MgF2
Al2O3
and ZnS
and meanwhile
the velocity was Mach2.5
and the time consists of 10s
20s and 60s. The temperature initial loads were from FLUENT thermal simulation. The thermal conduction analysis and the thermal convection analysis were finished in software ANSYS
in which the entire transient thermal analysis consists of modeling
meshing element
calculating and getting the results. The different temperature distributions based on varied time were gotten about the different materials. The results from analysis showed the temperature distribution of the structure of ellipsoidal dome
which could help the following coupled thermal-structure analysis. 2011 IEEE.

Mathematical models of structural optimization were established for the cam wave generator
then a conceptual model
by integrally taking its static and dynamic performance into consideration
which satisfied the model acted by four concentrated forces
while the dynamic optimum design was carried out. The topology optimization of the cam wave generator was performed based on artificial material density method
was obtained. And the size optimization of the cam wave generator was also executed based on the zero-order method in software Ansys after setting up its parameterized model. The optimized results indicate that its final volume declines to 1284.217mm3 from its 1397.830mm3
which reduced by 42.18% than the original volume of cam (2221.224mm3). Simultaneously
the static analysis and modal analysis were implemented
and the results show that the static and dynamic performance complies with the design requirements
proving that the results of dynamic optimum design are reasonable. The optimized results in paper are realizable in engineering. And the study method provides not only a reference to decreasing design mass and lowering inertia of the cam wave generator
but also an important basis of lightweight design of harmonic gear drive. 2011 IEEE.

In order to realize miniaturization and light weight of the strap-down inertial navigation system
and then to make sure that it works well under random loads
optimal design is applied to the strap-down inertial navigation support with the methods of topology optimization and size optimization. Firstly
based on the installation requirement of devices and connection requirement of the support and the carrier
the initial structure of the support is designed. Topology optimization with FEA software ANSYS is adopted on the initial structure to get the basic one. Then 5 critical sizes are chosen as design variables
and the support structure is optimized by means of size optimization to reach light weight with satisfying the requirement of dynamic stiffness. Finally
random vibration analysis is applied to the initial structure. In the mean time
random vibration test is carried out to qualify the analysis method. After the qualification
a random vibration analysis is applied to the optimized support structure to get the rms of displacement response and acceleration response of the support to validate whether the optimized structure is appropriate. The results indicate that the dynamic stiffness of the optimized support structure satisfies the design requirements
and its weight is lighter 49.38% than that of the initial one. This research can be a reference to the structure design of supports under random loads
and the result has been applied to the development and manufacture of a prototype aerocraft. 2010 IEEE.

The poison's ratio of plane plate samples taken from AM60 magnesium alloy was tested in this paper. A number of strain controlled fatigue experiments were also carried out on MTS to investigate the stress-strain behavior under different temperature conditions. The finite element analysis software ANSYS was employed to simulate impact process of shot blasting. Results indicated that at the specific temperature condition the residual stress and plastic strain increased with impact velocity increasing. At the specific impact velocity
residual stress reduced and plastic strain increased with temperature increment.
