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.

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.

Space optical remote sensor is very important in many fields of science and military significance. It is widely applied. Space optical remote sensor design and manufacturing require precision and stability. Focusing mechanics is an important component of remote sensors. Focusing mechanics can guarantee the stability of the entire mechanics focusing accuracy  therefore the stability of research focusing mechanics is very important. In order to guarantee the space optics remote sensor focusing mechanics the stability  takes steps the space optics remote sensor focusing organization mechanics characteristic analysis from the classics contact theory. This article uses international general non-linear finite element analysis software ABAQUS to carry on mechanics characteristic analysis to the space optics remote sensor focusing mechanics. First acts according to the focusing mechanics unique feature  carries on the finite element to the structural model the grid division  the material attribute disposition and the boundary condition indeed grades. Then establishment contact non-linear finite element model  and to focusing organization finite element model infliction unit action. Like this contacts the result and the equivalent static analysis result which the nonlinear analysis obtains carries on the contrast and the analysis. This article last count result modality is 90HZ  satisfies the space optics remote sensor structure overall modality to request to be bigger than 50HZ.This article when carries on the dynamic analysis  extracts the structure kinetic energy and the acceleration curve. In the dynamic analysis obtained transient response analysis modality 70.5Hz  this also is bigger than 50HZ. The dynamic analysis indicated the structure dynamic stability has the distinct enhancement  has provided certain foundation for the space optics remote sensor following development work  reduced the overall system development cycle. 2009 SPIE.
