In order to solve the problem that the weight of large scale theodolite's casting or steel plate welded structure is too heavy
lightweight design of large scale turntable based on topology optimization of continuum structure is investigated. Topology optimization could have better optimization efficiency because it can provide the optimized distribution of material and gain optimized structure in conceptual design phase of the structural design. In order to obtain lightweight and high stiffness structure
a truss turntable based on topology optimization of continuum structure is presented
and the validity of this lightweight structure is examined by finite element analysis. Comparing to the traditional welding steel turntable
the lightweight turntable
without changing the static displacement
can lose 386.48 kg(lightweight ratio is 26.7%)
and its first-order natural frequency raises from 167.02Hz to 173.71Hz. Meanwhile
in other aspects this turntable also has better performance than traditional structure. 2012 IEEE.

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.

A kind of small space telescope with 1m focal length was designed. By adopting finite element analysis technique
the structure of the space telescope was analyzed. The analysis results indicate that the surface profile accuracy of the mirrors reach to RMS 8.0nm with the working circumstances 4C uniform temperature change and space micro-gravity
the base frequency of the structure was 115 Hz. It shows that the designed structure has sufficiently high dynamic and static stiffness and thermal dimensional stabiLity. This space optical telescope is very suitable for little satellite application. 2011 IEEE.
