Stress-Strain Analysis Around Spiral-shaped Embedded Parts

Spiral-shaped embedded parts have wide application in the machinery and construction field. For example, the anchor rod used in the slope reinforcement, fixed use of anchor bolt, the rebar in the reinforced concrete and so on. There are many materials have spiral prism on their surface, for example, rebar, spiral carbon fiber, spiral nanometer carbon tube etc. Although the spiral parts is widely used, there is very few studies on the spiral buries parts and in the vicinity of the stress and strain analysis, and when studies on the force, often approximates the spiral surface to the smooth surface in computing, or obtains through experiments.In view of above questions, this paper use the finite element basic ideology as the guide, using the finite element analysis software ANSYS as tool, analyses the spiral buries parts and the stress and strain in the vicinity. In the paper, the first chapter expatiates the background, meaning, purpose of the study and the present research condition of this topic; the second chapter describes the generation, development, basic idea and solving steps of the finite element method, also simply introduces the basic idea of the ANSYS which is one of the finite element analysis software; the third chapter narrated the buries parts and the basic processes of the basic parametric modeling and analysis; the fourth chapter discusses the impact of the various parameters of the buries parts on the stress-strain, and draws the corresponding stress-strain curve; the fifth chapter make a summary of the whole paper, and carries a forecast to the following work. Making use of the completed stress-strain analysis of the spiral-shape embedded parts, attains the visualization of the analysis process, parametric modeling, and intelligence analysis, matrix and spiral-shaped embedded parts can be arbitrarily combined, their shape, size and material can be changed arbitrarily, establishes a more comprehensive foundation for other types of the spiral-shape embedded parts stress and the Strain analysis in the future.
