A brand-new smart wind turbine blade with magnetorheological fluid (MRF) sandwiched was proposed in the research. The three-dimension entity model of a 750 KW wind turbine blades was established through the use of UG software, and three kinds of MRF sandwich layouts were considered into the blade model, that is, at the blade tip, at the blade root and at the whole blade from the root till the tip. The MRF was simplified as Kelvin-Voigt model in order to implement the finite element analysis based on ANSYS software, so that the mode shapes of smart wind turbine blade were revealed under various conditions with three different layout forms of MRF sandwich wind turbine blades. Analysis results showed that the magnetic field would influence the mode shapes of the wind turbine blade with MRF sandwiched, especially the torsion vibration. When the MRF was inserted through the blade from the root till the tip, the blade would dramatically influence the torsion vibration, so that the torsion vibration, which originally would have happened at higher orders, would arise in advance. While the MRF was located at the root of wind turbine blade, the torsion vibration would be postponed to arise at the higher orders. Therefore, the MRF should be located at the blade root, instead of the middle and the tip of wind turbine blade. Smart sandwich wind turbine blade will provide a new way to the vibration control of wind turbine blade.

The performance of lock-rope mechanism affects the safe and efficient operation of mine hoisting system directly. The lock-rope mechanism with wedge angle 5° was designed by the mechanical analysis of wedge lock rope. Its entity model was established and the dynamic process of working is simulated by using the ANSYS/LS-DYNA. The results show that the wedge lock rope mechanism has the ability of self-locking. The strengthening institutions can largely eliminate the relative slip momentum between the lock-rope wedge-block and wire rope, which make the movement trend gentle, reduce the wear between the lock-rope wedge-block and wire rope and improve the security of wedge lock-rope mechanism effectively. The local equivalent stress of lock-rope wedge-block and wire rope are both present in the increasing distribution gradually from the upper to the lower.

We use the finite element software Midas FEA to set up space entity model, and discuss various factors including the stiffness of bearing, counteracting force of adjacent beam, the influence of the stiffness of bridge pier on reaction at support. In the practical engineering. Coupling of shear lag, stiffness of beam, bending-torsional coupling and partial load can also affect the redistribution of reaction at support. Through the simulation of the finite element software, we check the support of a railway bridge in Guangzhou city. In the end we found that the stiffness of beam can make the middle support have a tendency to increase. If we take all the factors into account, the force of the middle support will be greater than on the both ends of bearing and the force on the both ends of bearing will be approximately equal.

Previous research on soil compaction effect mainly focused on single pile, and the analysis of the effect in the group piles was less. In the actual process, though, the design and construction of pile foundation engineering are based on the form of group piles. In order to further study the effect of construction of group piles on an underground pipeline, a three-dimensional entity model is adopted. The displacement penetration method is used to complete the process of piling. The friction between piles and soil, pipe and soil, large deformation and nonlinear factors are taken into account. The process of piling is more in line with the actual process. Taking the penetration of row piles for example, the numerical simulation of the static pressure pile is carried on under the condition of different piling sequences and the change of stress and displacement are analyzed. The results show that all kinds of stress and displacement of underground pipeline produced by the penetration of row piles increase cumulatively as the penetration of each pile and the stress and displacement of pipeline produced by the penetration of each pile are related with the sequence of piling.
