Spiral Staircase

This paper first introduces the units which are used in general-purpose finite element analysis software ABAQUS simulation of steel and concrete as well as their material constitutive models, and then taking the simulation analysis of a spiral staircase for instance to draw displacement of a spiral staircase along the outer edge lines, the inner edge lines, and the axes of the stair treads under static loadings. By comparison, we find the rationality and insufficient points of the simplification of the spiral staircase to the calculation assumption which makes the axle wires as rod pieces. According o the displacement and stress of the spiral staircase, we give ​​some suggestions to provide some useful references to the designers of the spiral staircase.

Coiled Tubing

The purpose of this paper is to present how hand-calculations and a general finite element analysis program can be utilized to determine under what conditions coiled tubing (CT) could buckle helically in a vertical well. This is especially useful when determining loads on the tubing in a completion or work-over application. Two situations are considered as described below. • A Quasi-Static case when either: –Weight is slacked off from the surface. or –A bottom force that may be generated by reservoir pressure for instance. • A Dynamic case, which occurs when: –Weight is slacked off too quickly and the tubing impinges upon an object causing an impulse to be generated into the tubing. This paper presents the theory for the hand calculations and shows how the hand calculations may be utilized for a field example. In addition, the same field example is considered in the general finite element analysis program and the limitations of the hand calculations are discussed as well as the capability of the dynamic finite element model simulation. Hand calculations restrict us to the quasi-static scenario and only allow an assessment of the deformation of the coiled tubing deformation in the linear-elastic range. In contrast, the general purpose finite element analysis software allows for large deformation, and non-linear material behavior. In addition, the general purpose finite element analysis software allows for tubing evaluation locally after lockup of the tubing occurs. Generally hand calculations or quasi-static simulators have been used to assess the deformation of tubing during an impact event; these have proven to be inadequate because they cannot capture the transient event and do not model the inertial forces correctly. The general purpose finite element code provides better estimates of the deformation and stress state of the tubing. When assessing the dynamic behavior of tubing, it would be prudent to utilize the capability of general purpose finite element software to obtain realistic and an accurate assessment of the deformation and stress state of the tubing.

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.
