Abstract: The paper introduce that composing, principle and application example of a 3D Measuring system. It mainly applies technique of digital image processing, photogrammetry, optical grating measuring technique , in order to measure rapidly and correctly geometric data of a 3D –Object’ surface,Spots clouds data can be processed by ATOS system’s soft. The system supplys a rapid method to product fast measuring.

Abstract: The concept of collaborative design and mobile crane designing are discussed, a method of concurrent engineering technique applied in mobile crane designing within network circumstance has been proposed. And a detailed description is carried on a sort of key technology—the line browsing and revision, which is based on a re-development of the SolidWorks drawing software on the .NET platform, the parametric design module of mobile crane is complete. Besides, with support of digitized coordination design tool, the Mobile Crane coordination design platform is constructed.

Abstract: This paper analyzed the dynamic state of the water ring, which is formed through the exothermic process of steam condensation, and its influence on heat transfer during the operating process of the high speed paper machine’s drying cylinder. The influence of perturbation on the flow condition of the water ring was also discussed. This information was used to design the steam-knife gas supply system in the drying cylinder. This system provides a so-called steam-knife to attack the water ring, which would change the dynamic state of the water ring’s fluid level. This would ultimately improve the heat transfer efficiency.

Abstract: Human design is an inevitable trend and development in product design. To achieve the goal of human design, master's physiology, psychology, design data is key data that must be followed. Among them, the body size of the designer to determine is an important basis for product dimensions. The article first analyzes the characteristics of the body size, application method of body size and application procedures, finally, small kitchen appliances storage cabinets design as an example, analyzing the appliances the body size in the product design.

Abstract: The humanity of coding design for human-machine display interface in the product design is studied by experimental method. During the experiment, three character types, three eye distances from the display interface, five character sizes are adopted. The correct rate and reaction time are chosen as the evaluation indexes. Analyzed by ANOVA, mathematical models of the information coding are established. Mathematical models proposed in this paper can be widely applied for man-machine display interface coding design, and provide theoretical basis for different kinds of products design.

Abstract: The form and structure of Mongolia yurts reflect the quantity relationship beauty, the function beauty and nature harmonious beauty. But in the present, there also exist some problems of making and using. This paper has made some improvements on its material and components on the basis of keeping the traditional appearance and comfort. This new design makes its building more conveniently, living in it more comfortablely by adopting modern high technology and new materials, and also makes it stronger, lighter, and more beautiful. And the completed yurt and trailer united perfectly, so that it may have better moving property.

Abstract: The vibration of the horizontally vibrating conveyor (HVC) is excited by a vibration generator with four shafts which have eccentric quality. HVC makes the lump material to go forward by friction between the materiel and conveying trough. In this paper, a method based on the discreteness of time is adopted, and the influences factors of the transportation speed of HVC are discussed.

Abstract: The outskirts oilfields of Daqing Oilfield have characteristics of deep volcanic reservoirs, compact and complex lithology, and low natural yield of single gas well, so it is necessary to fracture these outskirts oilfields for exploitation. The traditional layer-by-layer fracturing gas test technique has low construction efficiency and poor reconstruction effect. Considering physical properties of compact gas reservoirs, conditions of wells and indexes of downwell tools, this paper studies and designs a layered fracturing string for deep compact gas reservoirs. It comprises high-index fracturing packer and matching downwell tools. The high-pressure compact gas reservoirs can be reconstructed layer by layer and on a large scale without moving string. The field construction shows that this string can meet requirements of formation temperature 180°C and working pressure 100MPa, and it can finish maximum 130m3 layered constructions thereby significantly reducing the field construction.

Abstract: Daqing Oilfield has more than 10,000 million kilograms of oil through tertiary recovery every year. However, eccentric wear of sucker rod and tubing severely impede the implementation effectiveness and large-scale utilization of tertiary oil production when injecting viscoelastic fluids containing polymer. Therefore, a plunger pump lifting viscoelastic fluid is designed based on the analysis of the mechanism of eccentric wear. The principle to reduce eccentric wear is increasing hydraulic and viscoelastic friction, and expanding clearance. Due to make use of the plunger pump lifting viscoelastic, laboratory experiment and field application have demonstrated effective reduction of eccentric wear, extend the life of the sucker rod and tubing, and improve pump efficiency.

Abstract: The “integration” in mechatronics does not concern only the technology but it implies an integration of design methods as well. There is a need for methods to model the functionality in a homogeneous way independently of implementation technology. Interdisciplinary knowledge, methodology and reference models are pointed out as factors that improve the design work of a mechatronic system, and a solution for the methodology and reference models was proposed.
