Publication number: 20210342506Abstract: A computer-aided engineering (CAE) toolkit is disclosed that streamlines and automates aspects of a CAE simulation to validate the designs of pressure-controlling components, such as BOP rams. The CAE toolkit enables a designer to provide a model of a pressure-controlling component, and to provide property values that describe aspects of the system to be modeled. Based on these inputs, the CAE toolkit generates a model for the system that includes the pressure-controlling component, as well as any other components that will be part of the simulation. The CAE toolkit can automatically generate a finite element analysis (FEA) model from the system model, and then use the FEA model to perform a simulation of the pressure-controlling component during operation. The CAE toolkit enables a designer with no training or experience with CAE or FEA techniques to perform and automate simulations of the operation of a pressure-controlling component design.Type: ApplicationFiled: May 4, 2021Publication date: November 4, 2021Inventors: Yaou Wang, Christopher Nault, Matthew Givens, Micah Threadgill, William Berry, Ke Ken Li

Publication number: 20210342507Abstract: A multi-disciplinary optimization (MDO) framework and workflow facilitates analysis and optimization of set of designs of a pressure-controlling component. The MDO workflow generally enables design workflow integration and automation, which can improve engineering efficiency, and enables automated optimization within the workflow automation, which facilitates performance and reliability improvement for product development. The MDO workflow enables the integration of computer-aided design (CAD), finite element analysis (FEA), digital manufacturing simulation (DMS), and optimization packages to facilitate testing and optimization of a set of pressure-controlling component designs. As such, the MDO framework and workflow improve the efficiency of the design process by providing a scalable solution for automating aspects of the design process for a set of designs of a pressure-controlling component, which may represent a product family or a set of competing alternative designs.Type: ApplicationFiled: May 4, 2021Publication date: November 4, 2021Inventors: Fei Song, Ke Ken Li, Caroline Stephan Rivas, Konstantin Bieneman, Thomas Yap
