Abstract: The purpose of this paper was to investigate the internal liquid sloshing and its effects on the ship motion. A mechanical model of ship motion under sloshing impacts is described. The lateral sloshing forces are included in the model. The nonlinear dynamical system is introduced to describe the sway motion of the ship. The results of the numerical simulation and the effects of the internal sloshing loads are analyzed. The feasibility of the approach is thus verified.

Abstract: This article mainly studies about the stamping processing of the tapered bearing retainer which mainly presents the finite element simulation of the tapered bearing retainer stamping process using Deform software. The author put forwards that how to analyze the stress and strain distribution laws, the shear stress, the stamping force and their influence law, also analyzes the influence the main parameter has on the stamping process and make the optimized selection.

Abstract: In this paper we have discussed the antinomies that can be identified in the development process of EDA tools for electromagnetic modeling. Namely the dichotomies between the usage of specialized modeling techniques and the need of synthetic methods, between the development of sophisticated methods and its integration in industrial frameworks, between the implementation of closed environment and the User request of an open simulation framework have been analyzed.

Abstract: Based on the Hu Lu Shan Wan crossing sea bridge, this paper calculated the temperature inside and outside the mass concrete while pouring. Besides, this paper presents the process of calculating and designing of the water-cooling method which could decrease the inside temperatrue of the mass concrete in the aspect of design principle. Thereby, it could solve the crack of concrete from one facet

Abstract: To construct warning model for technology patent can effectively get rid of the R&D trap, transaction trap as well as piracy trap. The warning model for technology patent on environmental engineering includes information collection, information regulation, information analysis, warning analysis, countermeasures provision and crisis management. According to the shift of warning evaluation index, it can raise the alarm at different degrees, and help to standardize, scientific and standardize the environmental engineering, so as to guarantee the profit of investment on environmental protection in China.

Abstract: This paper analyzed the current China market of numerical control machine, discovering that there was seldom consideration about Ergonomic, and also lacked the necessary experiment with study. This paper mainly analyzed Ergonomic about numerical control machine, and for project design example of numerical control machine to analyze its importance of Ergonomic in numerical control machine design. This project is going to considering more about the coordination between human and machine, joining the humanized design into the numerical control machine, letting the person also feel the concern of the design in work.

Abstract: From the basic concept of knowledge unit, with the efficient combination of axiomatic design and knowledge unit, using the hot runner system design of injection mold as the carrier, this article presents an information modeling method for concept product based on axiomatic design and knowledge unit as well as establishes corresponding model.

Abstract: Using the powerful parametric features of Pro/E modeling for the assembly of the track board, and building up Three-dimensional solid modeling. Finite element analysis with the simulation of mechanical motion to simulate the track through the soft ground of the forest were carried out. It can significantly reduce the design costs and speed up the development cycle to adapt of the requirements of the modern forestry industry.

Abstract: This experiment used high temperature short cycle hot-pressing process suppress the single composite straw, found that the density decided single composite straw bending capacity, inside combinative strength and bibulous ply the inflation rate important factors, among which the effect of internal bond strength is more obvious.

Abstract: Using the automation production mode of modern manufacturing industry for reference, a new industrialized PL-ISEE (product line based integrated software engineering environment) model was proposed by us in reference [8]. The middle part of the PL-ISEE architecture is data layer which is composed of the software components bus and core assets database platform to achieve the storage and managements of product line core assets data. In this paper, the architecture and its implementation mechanism of the PL-ISEE database platform is further researched. Whole platform architecture consists of core asset objects management service and assets database system. The data model and database schema as well as database views of the database platform are designed and created by using united product line concept model and data model. So, the database supporting platform’s functions and configuration also well satisfy the requirements of interfaces, tools and data integration as well as product line assembling production in the PL-ISEE. Therefore, the design and realizing ideas of the PL-ISEE database platform will be valuable to research product line engineering and methodology in future.
