Fluctuating Wind

The author puts forward a new insulation cross arm, uses the insulation and high strength composite materials (FRP), to replace the steel applied to the RPC pole cross arm, this not only has a full bar maintenance-free features, and can shorten transmission corridor again, for the construction of resource intensive transmission lines has important practical significance. In addition, this paper uses finite element analysis software ANSYS, considering the influence of fluctuating wind, in the modal analysis and dynamic response illustrates the actuality of cross arm application of composite materials.

Reactive Powder

In this paper, finite element model of reactive powder concrete (RPC) pole was established by using finite element analysis software ABAQUS, and the strength of RPC pole was checked. The results of finite element analysis and theoretical calculation are compared to provide a basis for determining the parameters used in finite element modeling and revising the theoretical calculation formula.

Air Cushion

The applications of air cushions are briefly reviewed in airships and tethered aerostats. The stress distributions of air cushions are simulated by finite element analysis software according to its load-carrying characteristics. Three kinds of interlayer forms are proposed and simulated thereafter. A best form of interlayer has been obtained via comparing the different analyzing results. In addition, an empirical formula is proposed for the differential pressures and load at the top of the air cushions, with experiments in which two kinds of air cushions are designed and their load carrying abilities are evaluated. Some advices are then provided for the designing and using of air cushions at the end of this paper.

According to uncertainty of the design parameters for large span truss of installing wave-maker, in order to avoid the waste of materials,the truss is analyzed based on the finite element analysis software ANSYS to find out its weaknesses and various parts of the deformation. On the premise of ensuring the intensity and stiffness, the weight of the truss is reduced by adjusting its sizes and selecting different profiles, so as to achieve the optimization of the truss of installing wave-maker.
