Abstract: Green Building and Information Model are the focus and developing tendency in the future. Therefore, the combination of the two will push and accelerate the progress of Chinese Green Construction forward. Thus this paper attempts to introduce the idea of GBIM, which takes information flowing technology as the nucleus, is the compound of data integration of BIM and integral management, is also the integration of information exchange and concordance for the tool software at different phases and in different professions with green construction process and tasks. At last, this information flow technology is applied to information flow model building in the green construction planning and designing.

Abstract: Manufacture process parameters will be obtained from experiments in research. Molding technology determines the mechanical properties and performance of the product. The influence of molding temperature and time are significant on the performance of water lubricated bearing, the plastic alloy is based on latex material, synthesized with different fillings, accelerators and other matters, and displays great mechanical and friction properties. The main performance included peel strength, tensile strength and wearing capacity. Optimization of manufacture process parameters and the orthogonal experiments on them were carried out by integrating the results of experiments and finally the optimal manufacture process was achieved. In the experiment, three-leveled orthogonal tests were conducted for the three systems to test the tensile strength, tearing strength, stress at definite elongation, hardness and tensile rate. The impacts of the respective systems were analyzed and the content of each component are determined to get the optimal formula.

Abstract: Water lubricated plastic alloy bearing molding technology determines the mechanical properties and performance of the product. The influence of molding temperature and time are significant on the performance of water lubricated bearing. The experiment selected five vulcanization temperatures from 110°C-190°C, and five time points from 5-25min to assess their influence on the tensile strength, stretching strength and abradability of bearing material. The corelation between temperature and time is analyzed and a vulcanization curve of plastic alloy production in the situation of 170°C (vulcanization temperature), 2Mpa (vulcanization pressure). The curve realizes a long vulcanization induction period at a fast vulcanization speed with a broad vulcanization plateau that reduces the vulcanization time in the production process and enhances efficiency massively.

Abstract: It is more difficult relatively of inflatable wing structure form-finding and molding. Baffles are the major control factors of wing aerodynamic shape maintaining. The article analyzes the limitations of span-wise baffles structure. Afterward, inflatable deformation of chord-wise baffles structure has been analyzed, applying finite element method, the lofting size of the baffles material has been calculated, and the inflatable wing molding technology has been identified according the principle of aerodynamic shape accuracy – the lightest weight.
