INVESTIGATION A NEW CONSTRUCTION TURBIN FOR AVIATION 
Abstract: After field visits, it is found that an easy use of an object may make users feel very 
positive, which also is a good experience. Therefore, a reasonable size of project is closely related 
to the feeling of user upon using. Ergonomic data is a size design data which is more suitable for 
many people. It works in such way that according to the use procedures of people, it will find 
corresponding data.
Key words: aviation, turbine, Ergonomic data, optimization, motore. 
 
An effective method for 3D lattice 
structure design is proposed using the 
volumetric distance field (VDF) based on 
analytic shape functions. By the innovative 
synthesis of lattice structure and VDF-based 
Boolean operations, a variety of computational 
models with intricate exterior shape and 
arbitrary lattice structure can be constructed. 
The significant advantage is that this design 
method can be easily applied to design highly 
complex lattice structure models. The 
important parameters such as the cell type and 
the size of lattice structure are controllable in 
customized MATLAB program. Design 
results verify that the presented design method 
is efficient to generate 3D models with 
required lattice structure. 
Through the SolidWorks software for 
elevator computer desk 3 d entity modeling, 
and using the ANSYS Workbench software to 
model the stress analysis of meshing and the 
applied load for elevating computer desk 
overall deformation and stress distribution, 
thus carries on the strength, stiffness and 
modal analysis, the model for the first six order 
natural frequency and modal vibration mode, 
the analysis of dynamic performance of the 
model. The analysis results show that the 
strength and stiffness of the computer table 
meet the design requirements, and verify that 
no resonance occurs during the working 
process. 
According 
to 
the 
applicable 
conditions of coating quality of two different 
coating models in the extrusion coating of 
lithium battery, the flow state of the slurry in 
the inner flow channel of the extrusion die is 
In China, traditional manufacturing 
industries are changing into innovative 
industries, and the labels of commodities are 
changing from "made in China" to "created in 
China. The design and production technology 
of the coffee machines have started early 
abroad, which are relatively mature, focus on 
innovative design and development. However, 
market positioning of most domestic coffee 
machines is not clear without innovation, just 
the introduction of foreign design and 
technology. It would cost much to model or 
copy domestic and foreign existing products 
because it would be costly to process with 
heavy dependence on others. Modeling 
functions are mostly stereotyped, which are 
"stiff" and lack a sense of design, and there are 
many shortcomings in the using functions. So 
there is a big space for improvement and 
development. 
The non-repetitive run-out(NRRO) of ball 
bearing critically influences the rotational 
accuracy of a machine tool. The quality of 
manufacturing can be improved by reducing 
the value of NRRO. This article developed a 
new ball bearing measuring system to 
investigate the NRRO caused geometrical 
errors of the bearing parts include inner and 
outer races and balls. The characteristic of the 
proposed measuring system as follows:(1) A 
high-precision hydrostatic spindle is applied to 
drive the inner race of the test bearing to obtain 
the system accuracy; (2) Measurable and 
variable axial preload is adopted to simulate 
the operating condition of bearings; (3) A 2 
degrees of freedom flexure hinge mechanism
