Abstract: In this paper, puts forward a kind of design method of multi-disciplinary engineering education for product design and development. In educational globalization era, higher education has paid more and more attention to cultivate innovation type of talents, who should receive interdisciplinary education. Mechanical design is an integrative subject. Every student should have a basic ability to finish a product design or plan. As a good mechanical engineer or product designer, should know different kinds of knowledge such as mechanical, materials science, industrial design, economics and so on. Along with the development of higher education popularization, the universities pay more and more attention to the talent cultivation and fusion. Followed by many scholars at home and abroad for interdisciplinary teaching research, its essence is expounded. But although the concept of education that interdisciplinary described the basic form, but to carry out interdisciplinary education in college education environment is not easy even if everyone knows it is very important. In order to solve this problem, the first thing is to break through the traditional education ideas, the second is to set an interdisciplinary teaching organization, the third one is to build a set effective incentive mechanism. So in the paper, puts forward a design method of multi-subjects amalgamation during the education of product design and development.

Abstract: Product is divided into four types which are hardware, software, processing material and service. Processing material is one typical kind of product among them. The hardware produced in several steps could be divided into single independent unit which is called “working process”. However, the flow is continual and there is no independent “working procedure” during the production of processing material. So how to evaluate and improve process achievement in the manufacture process of processing material becomes the study goal of this paper. This paper aims to explore the method for the process capacity evaluating of processing material as well as improving by researching a case on super-higher molecular weight polyethylene porous plastic. Statistical technology and knowledge are used together to improve the comprehensive ability of process.

Abstract: The optimal output speed of ESPCP system is caused by the coupling of multi-factors and it is a typical nonlinear optimization problem. A genetic neural network model for output speed, which takes the three factors of the content of oil viscosity, pressure difference of the pump two ends, magnitude of interference between stator and rotor as the input variables of this model, has been built with the help of Matlab (Matrix Laboratory) software. The model using genetic algorithm optimize the weights and thresholds of neural network, so the convergence and prediction accuracy of the network were improved effectively. After the simulation through samples study and by combining field data, it shows that the predicting results is basically in accordance with the observation data, and acquire satisfactory results. The research fruit provides a new approach and a route for optimal output speed optimization of ESPCP system when more factors are considered.

Abstract: In order to solve problems of long product development cycle, low collaborative work efficiency in complex product manufacturing firm, the approach of PLM-oriented collaboration digital process planning is put forward. The state of arts on PLM-oriented collaboration process planning and business requirements in complex product manufacturing firms are analyzed. The advantages and needs of PLM-oriented collaboration process planning workflow in complex product manufacturing firm are described in detail. Technology architecture on PLM-oriented collaboration digital process planning is founded also. Based on the development of a PLM-oriented collaboration digital process planning system (PLM-CDPP) in an aircraft manufacturing firm, the architecture of PLM-CDPP system based on the integration of CAPPFramework and Windchill is founded. Key technologies of PLM-oriented collaboration digital process planning system framework, business pattern, workflow and integrated model are discussed in detail. PLM-CDPP system has been applied in an aircraft manufacturing firm and good effect has been shown in practical engineering application.

Abstract: In order to solve arching and air leakage problems of sintering machine, based on the mechanical analysis to arching phenomenon, the hydraulic torque-loading device was designed, the simulation to the device was made using AMESim software, finds the reasons that system generating vibration and noise when running. By adjusting the structure parameters of hydraulic components, adding accumulator and damping system, solve the vibration problem of the system effectively, and can run smoothly in accordance with design requirements, the research provides a new method for solving arching and air leakage problems.

Abstract: Rub of roll and strip has effect on the texture form of surface strip, in IF steel rolling. The <110>//ND density decreased in surface strip in good lubrication condition rolling, the rolling texture become evenly in thickness direction, {111} texture is dominant, so that r-value increased. Otherwise, the {111} texture become unevenly and r-value decreased. It is must better lubricated for r-value rise, the conclusion is verified by the rolling text and texture analysis.

Abstract: Based on the ANSYS Software the hammer mill’s hammer applied lasers coating is feasible analysis. At first the paper describes the overall body hammer mill and hammer of traditional materials. Then the hammer is applied with lasers coating. Then simulate it and Fatigue calculation by ANSYS Software. By analysis of the coating hammer is found that the hammer’s life can develop well. So it has a nice economic Potential.

Abstract: Optimization method was applied to obtain optimal television packaging cushion for reducing drop impact response on television. At first, by establishing the parametric finite element model of television with packaging, the drop simulation was performed, and the equivalent stress distribution, acceleration response curve and other related parameters were obtained. Simulation shows that maximum acceleration is overload. Then, structural optimization of television with packaging was performed. The equivalent stress distribution and acceleration curves of optimal packaging and without optimal packaging for the independent components were studied. The results show that maximum acceleration is reduced and the cushioning performance is enhanced.

Abstract: With the purpose of clothing thermal-wet comfort, this paper chooses clothing materials to be the object of study. The research focuses on how performances of clothing materials and parameters which affect performances of clothing materials influence on clothing comfort. And this paper is proposed that "Fiber - Yarn - Fabrics - Clothing" can be made as the research system for the first time in the field of clothing thermal-wet comfort studying. According to the experiments, it analysis that these three variables— “fibers”, “yarn properties” and “fabric performance”— affect clothing thermal-wet comfort. Based on the contrastive analysis of test result, it can gain the effect of these three variables on clothing comfort. The result is, 1, in these three variables, the effect of yarn fineness on thermal insulation is the highest level of significance, and the second one is fibrousrawmaterials. 2,under the situation which other two ones among these three variables are constant in chosen laboratory samples of this paper, the knitting fabric which is with the cotton fabric, 14.6tex, jacquard weave is the best comfortable.
