A turbine aerodynamic optimization design system for marine gas turbines has been investigated to accelerate the turbine aerodynamic design process and perfect the research and development platform. The data can be conversed automatically with the self-compiling programs which integrate the 1D, S2 module of Concepts NREC, three dimensional modeling, analysis, and optimization of NUMECA. At the same time, the system can satisfy multilevel optimization design easily for different requirements. And the system has been used in the optimization design of a marine gas turbine. The results show that the design period can be reduced; after optimization the efficiency is improved about one percent; and the off-design performance is improved due to the rear loading technology.

ABSTRACT Herein, we phenotypically and enzymatically characterize the theoretical mutation Q579I in helix K and the already described clinical mutation K805Q in helix P of cytomegalovirus DNA polymerase for susceptibility to foscarnet. Q579I and K805Q recombinant viruses were hypersusceptible to foscarnet (respective mean 50% effective concentrations [EC50] of 0.12- and 0.19-fold that of the wild type). Three-dimensional modeling analysis suggested that both mutations favor the closed conformation of the enzyme to which foscarnet binds with a higher affinity.

Flying shear is the equipment that steel enterprises make shearing process on metal preform body for further processing. Crank flying shear has the advantages of high efficiency and good shearing quality, which makes it widely applied. The paper analyzes and studies crank rocking flying shear evolved from IHI rocking shear. And the paper makes kinetic analysis on crank rocking flying shear, applies Solid works software to make three-dimensional modeling, assembly and animation of working process on crank rocking flying shear, and makes optimized analysis and design on spare parts of flying shear combined with kinetic analysis results.

In the drive of market demand, postpress equipments developing rapidly. Because of environmental protection and energy saving, pre-coating technology has broad application prospects. But in China, the design of the machine are mostly generic and doesnt have a set of perfect design theory. There is no design innovation from the source. Using virtual prototype technology, the structural design of the key components of the pre-coated laminating machine to the paper feed mechanism is improved. Through the three-dimensional modeling, assembly and disassembly, adjustment mechanism simulation, motion simulation of mechanism, the physical, mechanical performance analysis, simulation, prediction, realizes fast implementation and optimization design, improves the processing and assembly technology.
