Interval Approach

Finite element simulations are well established in industry and are an essential part of the design phase for mechanical structures. Although numerical models have become more and more complex and realistic, the results can still be relatively far from observed reality. Nowadays, use of deterministic analysis is limited due to the existence of several kinds of imperfections in the different steps of the structural design process. This paper presents a general non-probabilistic methodology that uses interval sets to propagate the imperfections. This methodology incorporates sensitivity analysis and reanalysis techniques. Numerical interval results for a test case were compared to experimental interval results to demonstrate the capabilities of the proposed methodology.

Through the optimization of the design process, the application of the finite element method and the structural parameters design have avoided blindness of product design, reduced unnecessary waste, waste of material and time for example. The fuzzy constraints has been determined by the sensitivity calculation , and the use numerical method and procedures of chart to analyze and compare, the target setting in the specified range has been searched for the structure. Thus the optimal design got achieved.

This paper introduces motor rotor blanking die design process through specific terms of the process of stamping all. Mould design process is for structural analysis and process analysis of the parts diagram, based on it to determine the technology methods, select the structure of the mould, and make a necessary calculation to determine stock layout and the size of the work part. And choose a suitable punching machine. Finally, choose the parts from the manual of mould.This design also includes the use of AutoCAD software mapping die assembly and major parts map using UG and Pro/E software for 3D solid modeling and animation design simulation process. In addition, the punch and die processing choose WEDM and Programming. So consider the structural design of WEDM of the specific methods to avoid the conflict between design and processing, and guarantee the production reasonable.

This article describes the development of variable camber morphing wing, which is mainly composed of corrugated structures. The morphing wing with both leading edge and trailing edge morphing sections is proposed and the prototype model is designed by consideration of finite element structural analysis with actuation mechanisms and aerodynamic analysis. Through wind tunnel experiment with the manufactured prototype model, smooth actuation without harmful deformation under 20 m/s airflow is demonstrated. The observed deformation shape is well correlated with simulated shape by analysis. Thereby, the feasibility of the present morphing wing mechanism and design process are verified.

By describing the whole ship structure in its primary, secondary and tertiary components and by incorporating FEM structural analysis to a ship-like structure optimization, it was observed a significant capability of reducing the weight of ship structure, in an amount impossible to be reached by an usual design process, since, by nonlinear programming in a fast computer, the “best design” can be “selected” among thousands of different and feasible ones.

Spirillum serpens possesses a surface layer protein which exhibits a regular hexagonal packing of the morphological subunits. A morphological model of the structure of the protein has been proposed at a resolution of about 25 Å, in which the morphological unit might be described as having the appearance of a flared-out, hollow cylinder with six ÅspokesÅ at the flared end. In order to understand the detailed association of the macromolecules, it is necessary to do a high resolution structural analysis. Large, single layered arrays of the surface layer protein have been obtained for this purpose by means of extensive heating in high CaCl2, a procedure derived from that of Buckmire and Murray. Low dose, low temperature electron microscopy has been applied to the large arrays.As a first step, the samples were negatively stained with neutralized phosphotungstic acid, and the specimens were imaged at 40,000 magnification by use of a high resolution cold stage on a JE0L 100B. Low dose images were recorded with exposures of 7-9 electrons/Å2. The micrographs obtained (Fig. 1) were examined by use of optical diffraction (Fig. 2) to tell what areas were especially well ordered.
