The Study of Bolt Severance by a Bolt Cutter - Webinar

Severing a bolt is a dynamic and complicated event; the severance mechanism has been difficult to understand because the entire process takes less than one millisecond. Bolt severance includes both penetration of the bolt by the downward-accelerating knife, and fragmentation of the bolt on the wedge-shaped anvil underneath.

To better understand the bolt severance mechanism for reliable bolt cutter design, engineers at Pacific Scientific Energetic Materials Company used ANSYS Autodyn explicit dynamics software in Lagrangian mode. In this webinar, you will learn that fast pressure rise and high peak pressure are the most critical parameters for bolt severance. You will also take away an understanding of the five-step mechanism for bolt severance that the engineers extracted from post-simulation analysis.

Applications in Oil and Gas Safety and Reliability at Petrobras - Webinar

Analysis of Repairs in Metal-Composite in the Oil Industry
Carlos Eduardo Reuther de Siqueira, Petrobras

In the offshore oil industry, corrosion of metal pipes, ship sidewalls, and semi-submersible platforms is a problem due to contact with salt water. Repairing the defects in these metallic systems through welding usually requires transporting the damaged piece to a shipyard, which is a costly and time consuming process.

Engineers at Petrobras decided to explore the possibility of using carbon-fiber-reinforced polymer (CFRP) composites to patch the holes in metal components in situ. Knowing that the anisotropic physical properties of the metal and the composite could pose challenges in achieving a robust, failure-resistant repair, the engineers used ANSYS ACP in static analysis to model the system first. The simulations evaluated the stresses and strains in each layer of the composite and in the composite—metal system as a whole as part of a complete failure analysis. In this seminar, engineers present the results of these simulations, which strongly indicate that metal components can be successfully repaired in situ using composites, with little possibility of failure.

Basic Engineering Design of Flares on Oil Platforms Using Computational Fluid Dynamics
Paulo Roberto Pagot, Petrobras

Flaring burns waste gas that is a byproduct of oil extraction. Knowledge of the volume, shape, and radiation behavior of a flare is essential in designing an oil platform that will not be damaged by the flare and is safe for oil rig workers. The basic design of a flare determines the platform’s tower height, as well as whether additional protection, such as a heat shield, is needed.

In this webinar, Petrobras engineers discuss how they used ANSYS Fluent to model pipe burner annular air flares in 3-D.The flame profile, visible flame, soot emissions, incident radiation, and wall temperature were simulated under calm, average, and maximum wind conditions. Join us to learn how increasing wind speed bent the flame and altered its dimensions, thus heating up the platform structure. You will also discover that the incident solar radiation heats the structure faster than the convective wind can cool it. All of this can help you in your future flare engineering design projects.

Advancement in Turbomachinery Blade Rows - Webinar

Current turbomachinery end-user requirements of higher efficiency, performance and durability often imply higher aerodynamic, thermal and mechanical loadings, as well as less conventional designs. To deal with the increased complexity, higher levels of simulation fidelity are often required. While steady simulation methods remain a workhorse tool, transient methods are now more frequently used. However, there is an associated cost. Transient full wheel analysis can determine the circumferential variation of the flow, and response of the structure, but such an approach can be both expensive and time consuming. Fortunately, single sector models, with the ability to reproduce the full 360-degree fluid and structural behavior, are available, enabling designers to study candidate designs in an efficient manner. This webinar will focus on the latest Transient Blade Row (TBR) and Cyclic Symmetry modeling techniques, including the effect of mistuning, which enable the user to obtain full-annulus results by analyzing only a single sector. This webinar will also present the usage of these new techniques to solve two important phenomena, namely – Flutter and Forced Response.

Improving Turbocharger Design - Webinar

Increasing the power output of smaller engines, engine downsizing and reducing emissions are the current requirements of the industry. Turbocharged the engine is considered to be the preferred way to achieve this goal. Turbocharger design requirement include stringent specifications for performance, range, life, noise, size and efficiency - thus a multiphysics simulation approach is required. The process is accelerated by performing initial design iterations using 2D tools, to quickly filter designs, and then carrying out full 3D analysis on relatively smaller set of candidates. In this webinar we will discuss how ANSYS tools can be used for fast, comprehensive and high-fidelity turbocharger design. ANSYS provides a full set of 1D, 2D and 3D tools within an integrated framework, ANSYS Workbench. A goal driven optimization using 2D through flow solution will be demonstrated for rapid scanning of candidate designs. A detailed mechanical and CFD simulations will be discussed to verify the structural integrity and the aerodynamic system design of the full assembly, ensuring that all performance requirements are met.

Integrated Design System for Turbomachinery Application - Webinar

Turbomachinery (or, more generally “rotating machinery”) plays a key role in many industries. With increasing competitive pressure and end-user requirements that are often driven by global trends, manufacturers are challenged to deliver reliable, high performance and efficient machines within the constraints of time and cost. Requirements for rapid, high-fidelity simulation have never been greater, and the cost of “getting it wrong” has never been higher. ANSYS provides a complete virtual simulation portfolio that covers all aspects of turbomachinery design and analysis. Leading turbomachinery companies use ANSYS integrated tools starting from preliminary design right through to final optimized design. This webinar presents industry trends and challenges, and addresses how leading manufacturers use ANSYS simulation tools, within an integrated environment, to address these challenges and deliver superior products.

Model-Based Systems Engineering — Business Opportunities and Overcoming Implementation Challenges - Webinar

This webinar is intended for manufacturing organizations that build complex electromechanical systems that are increasingly becoming software intensive. It will cover the business opportunities and implementation challenges facing engineering teams as they implement model-based systems engineering technology and processes. We will report on industry best practices and lessons learned based on CIMdata’s on-going market research and recent MBSE survey conducted with ANSYS. The initial summary results of the MBSE survey will be presented highlighting areas where MBSE processes and tools are being effectively used today as well as areas for improvement that promise the greatest future business impact.

The webinar is intended to help senior engineering managers to understand how to formulate an assessment of the baseline maturity of their own organizations with respect to implementing MBSE capabilities. We will describe how an open MBSE platform that integrates the current siloed product development domains of embedded software, controls, electronics, and mechanical can impact key business metrics identified in the CIMdata survey results (e.g. time to market, innovation, reduced warranty costs, improved software quality, etc).

Enhancements to Bolt Modeling in ANSYS Mechanical and MAPDL - Webinar

Threaded bolt connections are a common structural component in many industrial applications and most of these connections are subjected to pre-tensioning conditions. To accurately assess the operating integrity of the components, the effect of the bolts must be included in the simulation. Traditional techniques require significant user effort and computational resources. ANSYS Mechanical and MAPDL 15.0 introduce a capability to account for the effect of threaded bolts without explicitly modeling the threads. This enhancement greatly reduces the required effort to create the model and the computer resources required to solve it.
