This paper introduces a kind of comprehensive evaluating method combined qualitative with quantitative analysis - analytic hierarchy process which is based on the provision of China Evaluation Standard for Green Building on comprehensive evaluation index system on Green building. Through examples, we will provide specific algorithm of this method for the purpose of more scientific and reasonable evaluation results.

For research on comprehensive performance of crankshaft in piston compressor, multi-body dynamics model was built to get mechanical boundary conditions of the crankshaft, and the fatigue strength was verified; Finite element model (FEM) of the crankshaft was established, and the 1st 6 modal of the crankshaft was obtained. The results showed that fatigue strength and dynamic characteristic of the crankshaft was qualified. Theoretical basis could be provided for optimize the crankshaft’s structure by fatigue strength and modal analysis.

In order to improve the durability of reinforced concrete member, fiber reinforced polymer (FRP)-reinforced concrete member is introduces. Monotonic loading was applied to a reinforced concrete beam and FRP-reinforced concrete beam, in order to investigate the failure progress and characteristics of FRP-reinforced concrete beam.. The presenting study provide a basis for improving the design method for FRP-reinforced concrete member.

In order to achieve higher speed and better efficiency of the plastic buckle molding, Imageware, the reverse design software, was adopted in this paper to process the point cloud data of the plastic buckle, mesh feature lines and reconstruct the surface,and then the reconstructed plastic buckle model was imported into UG and saved in STL format with the powerful surface repair function of UG to suture discontinuous surfaces. Mold Wizards of UG, the mold design module, was used to create mold assembly model, design parting surface, generate three-dimensional solid model of molding parts according to STL format saved previously and eventually the injection-molded plastic buckle was analyzed with Moldflow / MPI. As was indicated, the optimized design parameters tally with the experimental results basically.

Through exposure test of FRP-reinforced concrete member in littoral test area of temperate marine zone, the durability and constructional measures of FRP-reinforced concrete structure are investigated. The test results show that FRP shell on the surface of FRP-reinforced concrete member is effective in avoiding wave flush, freezing and thawing damage, preventing chloride ion corrosion and improving durability. On the other hand, reliable measures should be taken to protect concrete structures with no FRP shell on the surface. Based on above, the provided reference for evaluation durability of FRP-reinforced concrete structure, and proper constructional measures for FRP-reinforced concrete structure are presented.
