Uncooled infrared bolometer arrays have become mainstream low-cost thermal detector used in applications such as firefighting, security and surveillance, and environment temperature control for food operation. In order to resolve the pixel structure’s stress problem of microbolometer, this paper adopts finite element analysis method to model and analyze the mechanical properties of pixel structure. Several results of the stress and displacement are presented and the influence of structure optimization on the stress is also analyzed quantitatively. The research provides a good foundation and mechanics reference for mechanical design of uncooled microbolometer.

Working Principle

The tricycle reducer is widely used in many fields such as mining, petroleum and building materials because of its characteristics of large transmission ratio, compact structure and wide application, as well as its excellent carrying capacity and low cost. In order to understand the force of three-ring reducer, the finite element analysis method should be adopted. This paper, starting with the structure and working principle, carries out the multi-tooth meshing effect and the whole machine statics analysis, aiming to provide a reference for the optimization and perfection of the products.

The purpose of this study was to determinate , using the Finite Element Analysis Method, the mechanical stress in a solid body , temporary molar restored with the self-curing GC material. The originality of our study consisted in using an accurate structural model and applying a concentrated force and a uniformly distributed pressure. Molar structure was meshed in a Solid Type 45 and the output data were obtained using the ANSYS software. The practical predictions can be made about the behavior of different restorations materials.

Abstract In this paper, we study the energy absorption of metamaterials composed of unit cells whose special geometry makes the cross-sectional area and the volume of the bodies generated from them constant (for the same enclosing box dimensions). After a parametric description of such special geometries, we analyzed by finite element analysis the deformation of the metamaterials we have designed during compression. We 3D printed the designed metamaterials from plastic to subject them to real compression. The results of the finite element analysis were compared with the real compaction results. Then, for each test specimen, we plotted its compaction curve. By fitting a polynomial to the compaction curves and integrating it (area under the curve), the energy absorption of the samples can be obtained. As a result of these investigations, we drew a conclusion about the relationship between energy absorption and cell number.

With the continuous development of urban construction projects in HebeiProvince, the rise and development of high-rise buildings and undergroundengineering, the design and research of foundation pit support structure has become more and more important. The design of the foundation pit support structure directly affects the settlement and position changes of the building itself and the surrounding stratum. In this paper, the characteristics of foundation pit support are analyzed, and the related theories of finite element analysis method are introduced. Combined with the actual situation of Hebei Province, the finite element analysis method is used to simulate the construction method of foundation pile anchor support structure system. The design was analyzed and studied.
