University NAGOYA (Japan) 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 |
