Aim at the actuality of badly lag of directive data transmission, badly reality of VRML format transmission, and incapable of modification to concretely structure, this paper develops quadratic exploitation based on Unigraphics soft through UG/Open API, makes it into realism when someone in cooperative net have forwardly modified the materials structure, then the operate instruction which has made...
Smart home is a house that uses information technology to monitor the environment, control the electric appliance and communicates with the outer world. Smart home is a complex technology, at the same time it is developing. A sample house environment monitor and control system that is one branch of the Smart home is addressed in this paper. The system is based on the embedded system and can act as...
The knapsack problem is one of the classical NP-hard problems in operations research. It has been thoroughly studied in the last few decades and several exact algorithms for its solution can be found in the literature. In this paper, we propose a new ant colony optimization (ACO) algorithm for solving the knapsack problem. Comparing with the basic ACO, this improved algorithm combines inner mutation...
Culture is a very important factor in affecting design and promoting its development, only by deeply rooted in culture could design make progress. The development of the Chinese design has to absorb Chinese culture into it. By analyzing the relationship between national culture and characteristics of design in different countries, and the relationship between Chinese culture and design, the current...
This smart sport underwear, where sensors, electrodes, and bus structure are all integrated in the textile material, make it possible to monitor the physiology status of the user. By providing direct feedback to the users, they can act on the level of awareness and allow better control of their own conditions
Recent years production accidents keep appearing in coal-mines of our country. The author analyzes different factors that may cause accident and comes to the conclusion that most of the accidents are related to human factors. Among coal-mine equipments the safety and rescue devices have been responsible for protecting coal-miners against injuries and reducing economic loss of coal-mine corporation...
Why productions are connected with animation and cartoon? An important reason is that the aim of the product design is to design and guide a new way of life, and that animation and cartoon are just good at displaying human lifestyles by telling the story. This kind of display is dynamic, virtual and dramatic. Through animation and cartoon art we can find a better presentation for making product innovative,...
Fitness design fundamental research in the thing class sorting system, is one kind of person's factor consideration standardized method for the purpose of proposing. This article as an example of Pu Tian sorting system from the man-machine work criterion fitness, the man-machine work rhythm fitness, the man-machine working pattern fitness, the man-machine work mood fitness, four aspects carried on...
Design symbol has the fatal meaning to the design works. This paper expatiates the design symbol in the context of culture, demonstrates the emotional experience inspired by design symbols. As one part of culture code system, design symbol system makes its role in keeping and developing the culture. As the medium between people and design works, design symbols excite the affective resonance. In the...
The computer aided engineering (CAE) is aiming at the numerical simulation-the important link in the advanced digital manufacturing. Its second development based on ANSYS platform can be carried out often. In common, the Visual Basic and APDL are important development tools and are applied in the product design at the same time. In the paper, the secondary development flow and method based on ANSYS...
Owing to some problems in their stability of existent building structures, the general software ANSYS is adopted to establish the finite element solid models of rectangular reinforced concrete long columns confined with CFRP sheets under eccentric compression and used to analyze the influence of CFRP sheets to these structural buckling loads. Height of columns, layers of CFRP sheets, concrete grade,...
To solve the problem of hydraulic bumper of a type of large-caliber sniper rifle that its flow gap area can not be adjusted, this article improved its structure with the help of computer. The flow area of hydraulic bumper was redesigned to be a groove which has variable depth. The outline of the groove was created by cubic spline. A set of optimized parameters were got by using the optimization toolbox...
Planetary transmission of ultra-precision planar polishing has crucial effects on polishing path and quality. It studies the PE-1 style of ultra-precision double sided polishing machine. Combining with three-dimensional model in solidworks, the virtual prototype of the planetary transmission system is established based on ADAMS. The veracity of VP is validated by dynamic simulation. It analyses the...
With the fast development of era and the constant progress of social civilization, promoting the fast transition of thinking ideas of people greatly, people become self-respected and pursue individual character life more and more, this makes future product design move towards the pluralism and individualized trend. The individualized products can cater to people's taste even more and possess stronger...
Ontology application for employment or HR management is becoming an increasingly important task with the development of semantic Web technologies. With the expanding scale of online-recruitment, such failures as low search efficiency, precision ratio, and recall ratio emerge and become worse. According to the actual state, we propose an intelligent recruitment platform with a skill ontology-based...
In order to organize the modern R&D enterprises to participate the product commercial development activities, diverse research fields and technology are involved. In this paper, the features of manufacturing enterprises taken part in the enterprises informational plan are analyzed. Then, the method and content about the commercial information expression is proposed. And the detailed analysis is...
Giant magnetostrictive actuator (GMA) is a kind of new-generation actuator. The application of GMA is limited due to the inherent hysteresis and the nonlinearity. And the response speed can not achieve a satisfied effect. To solve the problem, the mathematical model of GMA was established in the paper. According to this model, a PID controller was designed and developed. The effect of the PID control...
First of all the essential procedure of design catalogue is expatriated on. And the methods of function coding and mechanism coding are defined according to the features of function and mechanism. On this base, the function table and mechanism table including evaluation criteria are constructed. Then because different users have different interests in the importance of various evaluation criteria...
Over one century since air-conditioner was invented, people have been using the traditional means of air-conditioning. With the industrialization of human society and improvement of living quality, air-conditioner has been widely used in people's life but at the same time, created a series of problems, for example, waste of energy, air-condition symptoms, damage of ozone layer, etc. Nowadays, people...
Based on object-oriented technology and fully refer biology growth mechanism, starting with the most basal and nonobjective function of part and structure in product, abstracting its function feature, establishes the function structure which likes biology cell, so called cellular structure, defines the structure element of cellular structure which likes biology gene, so called gene element. Taking...
