Today, the offshore oil and gas and wind power industry is a heavily regulated segment, and current standards have established restrictions which yield a very limited weather window for submarine cable installations due to experience with cable failure in bad weather. There are two main limiting factors in current practice during cable installation of an S-lay configuration: the design criterion for the minimum allowable radius of curvature in the touch down point and the avoidance of axial compression in the touch down zone. Accurate assessment of the cable integrity during offshore installation has drawn great attention and is related to the existing available analysis and design tools. The main purpose of this paper is to develop and propose a quick and easy custom-made analysis tool, which is able to export similar results as sophisticated finite element analysis software. The developed tool utilizes analytical equations of a catenary-type submarine structure extended to account for varying cross-sections with different weights and/or stiffnesses, as is the real practice. A comparative study is presented in this paper to evaluate the significance for the modeling of the “out of water” cable segment required for accurate safety factor quantification during a laying operation. The efficiency and accuracy of the proposed tool are proven through a validation study comparing the results and the computational effort and time with commercial finite element analysis software. The analysis error in the case of not modeling the “out of water” cable part is significant, especially in shallow water areas, which proves the importance of using the proposed analysis tool.

Abstract The objective of beverage and food can design is to minimize cost while maintaining structural integrity. The package must satisfy requirements of internal pressure, drop pressure, and axial column load. Finite element analysis allows the designer to examine these structural constraints before prototypes are created so a larger design space can be examined in a shorter time. Hyper-Can was created as a tool in the Macintosh environment to automate the design and analysis process and reduce the design cycle time in a user-friendly way. Hyper-Can contains templates or families of designs of standard beverage and food can ends and bodies that calculate geometric information for finite element analysis pre-processing and fill and metal volume calculation using external Fortran code. Hyper-Can allows the designer to manipulate a standard design from the conceptual stage to analysis utilizing a simple graphical interface on the Macintosh.

Calculation the gear bottom bending strength and the gear surface contacting stress are traditional wheel gear design method. It takes a long time to design and works out parameters for gears system. Nowadays, the optimization design and reliability theory are introduced into modern engineering, we can make full use of the calculator tool to look for the best design parameter. Modern powerful finite element analysis software packages such as ANSYS are now not only an analysis tool but a design tool as well. This kind of technology makes planet wheel gear system design quantified precisely combining with physics principles in one. In the study, we designed a planet carrier with traditional method and built three dimensional full-scale model in Pro/E software. Based on finite element analysis, the finally result of stress distribution and deformation distribution is obtained. The results indicate that the design can meet the requirement.

Welding Processes

Weld residual stress and distortion are inevitable during welding due to rapid local heating and cooling, high-temperature material reactions and weld-fixture effects. To predict weld residual stress and distortion, an engineer has to understand welding processes and the finite element analysis method. It is difficult for an engineer without finite element background to calculate the weld residual stress and distortion. With the development of weld modeling technology, automatic meshing generation, and high performance computation, a web-based analysis tool (E-Weld Predictor), was developed to predict weld residual stress and distortion. This allows an engineer to calculate the weld residual stress and distortion on line. The engineer does not need to have finite element analysis knowledge to perform the calculation. By providing welding parameters, defining a weld joint, giving geometry dimensions, and specifying a material, weld residual stress and distortion are automatically calculated in a remote high performance computer. A report will then be sent to the engineer to review. This paper introduces the development of E-Weld Predictor. The software structure, the theory, the implementation, and the validation of E-Weld Predictor are discussed in detail. It also shows the simulation process of applying this software in predicting temperature, microstructure, residual stress and distortion.
