This paper deals with the aerodynamical problems of rigid flapping wing at low Reynolds numbers with emphasis on investigating the lift generation mechanism of simplified ornithopter. Theoretical analysis and Particle Image Velocimetry (PIV) were conducted to analyze and verify the lift generation conditions. The results revealed that the rigid flapping wing will generate lift under the conditions of both angle of attackαand free incoming flow velocityvwere not zero. With the wings flapped periodically, there were votexes formed, developed and shedding alternately. The calculation of curl demonstrated that the greater of flapping speed, the greater of curl. The statistic of circulation suggested that the circulation generation of flapping down was greater than that of flapping up, the circulation difference contributed to the lift generation. The difference of circulation will increase along with the angle of attackαin the circumstances of free stream velocityvand flapping speedπand flapping amplitudeΦmatched well.

The ACO is studied and improved to be used in continuous domain. The solution space is decomposed into finite grids then the ACO can be used to optimize the contraction and expansion factors of the universes. The reference cable angle is calculated and the helicopter cable-orientation control system is designed. The adaptive fuzzy controller with variable universe based on ACO is adopted to keep the ground velocity of helicopter at zero. Simulation results indicate that the controller designed in this paper has a better performance than common variable universe fuzzy controller.

An experiment was carried out to evaluate the effects of initial phosphorus concentration (0, 0.54, 2.7, 5.4, 10.8and 16.2mg/L) on chlorophyll a (chl-a) contents and extracellular polysaccharides (EPS) contents of Scenedesmus quaclricauda, which was separated and purified from the Three Gorges reservoir (TGR). The different conditions of initial phosphorus concentration have different volumetric meanings. 0mg/L, 0.54mg/L and 2.7mg/L are P-limited, 5.4mg/L is P-standard, 10.8mg/L as well as 16.2mg/L, is P-rich. Results showed that the growth period of Scenedesmus quaclricauda was shortened, and the stationary phase happened earlier than usual in the condition of P-limited. However, the growth period of Scenedesmus quaclricauda got a proceeding extension in the condition of P-rich. The condition of P-rich had an inhibitory effect on the growth of Scenedesmus quaclricauda during lag phase and exponential phase. It seemed that there was an inhibition threshold of initial phosphorus concentration, which was between 5.4mg/L and 10.8mg/L. And the inhibitory effect decreased with the initial increasing phosphorus concentrations from 10.8mg/L to 16.2mg/L. One-way analysis of variance (ANOVA) was used to compare the effects of both P-limited and P-rich and their impact on sEPS contents and bEPS contents of Scenedesmus quaclricauda in the cultured time segments. The results showed that there was no significant difference at sEPS contents or bEPS contents either in P-limited or P-rich. In the whole culture period, the sEPS contents of Scenedesmus quaclricauda had small fluctuations but kept nearly unchanged. Whereas, the bEPS contents increased in the beginning 8 days, and then dropped to the level, which is slightly higher than the initial contents, and keep fluctuating steadily. The EPS contents were just floating up and down at the initial value and had not shown a trend of rising or falling precisely. Our results suggest that phosphorus concentration could change chl-a contents but have no significant effect on EPS contents.

Machine tool bed, which supports headstock, tailstock and other functional components, is one of the important structure parts of machine tools. Precision grinding machine tool beds are designed by the authors with artificial granite and cast iron respectively for research. Their three-dimensional models were established via software SOLIDWORKS and then imported into the finite element software (ANSYS) to simulate for the first eight modal frequencies and the corresponding vibration modes. Simulation results show that the first eight order natural frequencies of artificial granite bed are better and the corresponding maximum amplitude of vibration modes are decreased significantly than cast iron bed. The dynamical properties of artificial granite bed are obviously better than grey cast iron bed.

By analyzing stress contours and deformation contours of the primary bracket, we can know that bracket material is more, contours proves too safe for bracket strength and stiffness. To improve the material utilization rate, topology optimization for bracket is carried by using topology module (DOE) of finite element analysis software workbench14.0. the main design parameter was set up, accordingly to accomplish analysis about the relationship between design parameter with quality. on the basis of analysis results, we improved primary structure that made the bracket quality reduced by 10% and executes verification, we obtained the reasonable structure finally.
