This paper discusses the unfolding form of the folding wing and its application to special UAV. The main investigations involve aspects such as unfolding process of the special UAV’s folding wing, contour structure of the complete unfolding, the choice of composite materials for the folding wing and its overall performance parameters. Modeling and dynamics analysis are made for all-composite wing through finite element analysis and calculating software. The unfolding process is also simulated. The result shows that the wing’s first-order frequency is low, second-order frequency and third-order frequency are close at different sweep angles. The wings are apt to happen flutter coupling in flutter analysis. With the continued folding of the wing, the wing’s natural frequency decreases significantly at different orders. The conclusions can provide effective basis for the study of wing rotational rate, unfolding time and impact action.

The self-elevating drilling units are widely used in the offshore industry for oil and gas exploration. The drill floor structure is the main part of the drilling package for a self-elevating drilling unit due to its key function. Its structural strength checking is of great significance on account of the special structure features and the complex combined loading conditions it suffers. The sufficient structural strength of the drill floor is the base and guarantee for safe drilling and extraction. The finite element method was applied to calculate the structural strength of the drill floor directly considering different load cases which was the combination of environmental loads, permanent loads, variable function loads, and reaction forces from structures and equipments. Total forty load cases were set in the finite element analysis. A detailed finite element model without simplification of the drill floor was built correctly so that it can show the accurate stiffness of the real structure. Based on this model, the design method and the design criterion of the drill floor were described in detail. The environmental loads were calculated according to ABS MODU rules. The influence of the direction of the environmental loads on the drill floor were studied and concluded. Since the drill floor was not just welding with the cantilever beam, the boundary conditions were also particularly introduced owning to the complex connection between them. After finite element analysis and calculation, the stress distribution of the whole drill floor which includes the main girders and derrick supports were obtained. The locations with high stress were found so those places should be paid more attention. The curves which show the stress variation according to the environment loading direction were drawn and their characteristics were found. The load case and the load which have the main effect on drill floor structure were found. As a result, the suggestions for design improvement were put forward for the structural design, and the finite element analysis was run again to test and verify the design improvement. This paper can provide meaningful guidance for the future design of the drill floor.

Based on the analytical theories of the joint surface, finite element modeling method of two kinds of joint about rails and bolts were studied. The finite element model of the engraving machine is built and its static and dynamic characterization is analyzed by the universal ANSYS. By this way, unreasonable structural design of engraving machine can be conducted, which will provide support for the optimization design of the structure. The correctness of the modeling method of joint surface is confirmed.

The design of lifting device for a large-scale dynamic sculpture at tourist district was introduced. According to its own characteristics of lift device, the "back-to-back" style of rack and pinion for the lift system was designed. It was used the finite element analysis software to analyze the strength of the rack and pinion which is a key part of the lift device. According to the stress of dedendum for the pinion is too bad, it was proposed that increased the radius of the fillet for dedendum.

The troweling of wall space is an essential decorative process and the development of wall-troweling robots, which are expected to release labors from the burdensome pargeting tasks, is growing to be a promising sector in todays architectural industry. In this paper, a static analysis is conducted for the key components of troweling disk and vertical guiderail, based on the proposed virtual prototype of wall-troweling robots. The stress distribution across these components provides a sound basis for the structural design. With the finite element analysis module of SolidWorks package, the paper investigates the modal characteristics of the key components operating under practical conditions. The research effort in this paper is contributive to the design and manufacturing of wall-troweling robots.
