FEA finds best design for bearing seal on turbines

FEA finds best design for bearing seal on turbines | Wind Energy | Scoop.it
By Paul Heney, Editorial Director An engineering firm that designs seals for wind turbine bearings used finite-element analysis software to simulate the performance of a seal or gasket and then an optimizing package to runs through hundreds of design and material possibilities to find a best fit for a wind turbine’s wide operating range. “Reliable
Mahesh Kailasam's insight:

Designing components that operate well under a variety of operating conditions, while taking into account various uncertainties such as material property variations or manufacturing tolerances, is simply essential today.

FEA Aids Deepwater Horizon Failure Forensics

FEA Aids Deepwater Horizon Failure Forensics | Wind Energy | Scoop.it
DNV uses Abaqus finite element analysis to study blowout scenarios
Mahesh Kailasam's insight:

Great example of the use of advanced simulation to try and understand WHY something happened, to understand the physics, and to then be able to develop science- and engineering-based solutions.

 

Also pretty interesting use of SolidWorks and Abaqus to perform simulations on "as-exisiting" structures as opposed to "as-designed" structures. In addition to forensics, this opens the door to condition-based maintenance decisions based on realistic conditions and realistic simulation technologies.

Mahesh Kailasam's insight:

Even though this application is focused on Oil & Gas, it applies to cables for offshore wind farms as well. Furthermore FEA can be used to assess the safety of buried cables from anchor drags, ice scouring etc. Exciting stuff!

Sweep-Twist Design Offers Higher Output at Lower Load

Sweep-Twist Design Offers Higher Output at Lower Load | Wind Energy | Scoop.it
Wind turbine blades' basic physics and economics are relatively simple. For one, their power output is roughly proportional to the square of blade length.
Mahesh Kailasam's insight:

The use of advanced 3D modeling and simulation is a cost-effective way to develop and evaluate new technologies such as this new blade design. Many of the questions at the end of this article can also be answered by the use of additional simulations for composite fatigue, adhesive failure, and for fluid-structure interaction assessments. See http://www.3ds.com/solutions/energy-process-utilities/industry-experiences/sustainable-wind-turbines/ for more details on how a 3DExperience for Wind Turbines can significantly speed up time to market with improved reliability and lower costs, including assessments and planning of the manufacturing processes.

cordasia willis's curator insight, September 14, 2015 11:12 AM

This relationship pushes designers to create increasingly longer blades for harvesting additional energy. Secondly, as blades get longer, weight increases  by about the cube of the length – which raises raw material costs. This correlation sends designers in search of weight-efficient geometries that are strong and rigid enough to weather the increased loading inherent in longer blades.

How simulation improves gears for wind turbines

How simulation improves gears for wind turbines | Wind Energy | Scoop.it

Optimizing gear tooth shape in an efficient and accurate manner results in more durable gears for yaw and pitch drives in wind turbines. This in turn allows for more reduced in-field failure and allows wind turbines to continue generating electricity at a winder range of wind conditions.

Realistic Simulation helps develop better wind turbine gears

Realistic engineering simulations can help enginners understand the stresses that arise in gears under various situations and so assist in the evaluation of solutions for better gears. These simulations provide significant value because they can include complex effects such as those arising from the bending of the shafts on gear tooth contact and do so in a dynamic sense. Excellent agreement with experimental measurements further increases confidence in the use of these simulation methods.

Industrial Sector: Wind . SIMPACK MBS Software

Industrial Sector: Wind . SIMPACK MBS Software | Wind Energy | Scoop.it
SIMPACK is a general purpose Multi-Body Simulation (MBS) software which is used for the dynamic analysis of any mechanical or mechatronic system.
Mahesh Kailasam's insight:

Truly integrated flexible multibody simulations (MBS) have been sort of a holy grail that simulation players have been pursuing for many years, with varied and I would say mostly limited levels of success. The acquisition of SIMPACK by Dassault Systemes (3DS) brings together one of the world's leading MBS solutions with advanced nonlinear physics simulations (SIMULIA Abaqus technology) and systems engineering (CATIA) solutions, not to mention composites modeling and simulation capabilities. It is going to be pretty interesting to see all of this being integrated into the Sustainable Wind Turbines Experience that 3DS launched last year.

wind energy parts such as blades, bearings, gearboxes, generators, towers and control systems. In particular, the company is leveraging the technical knowledge it has gained from projects in marine environments such as the North Sea and the Gulf of Mexico in the offshore wind power domain, which requires deep-sea installations similar to offshore plants.

Hail Impact Simulation with Smoothed Particle Hydrodynamics

http://www.3ds.com/fileadmin/PRODUCTS/SIMULIA/PDF/tech-briefs/cross-simulation-hail-impact-smoothed-particle-hydrodynamic-explicit-12.pdf

Mahesh Kailasam's insight:

Accurately simulating hail impact on any body is challenging due to a variety of reasons such as capturing the properties of the ice, the breakup, and the subsequent interactions between the smaller pieces and the impacted entity. Simulating hail impact on composite structures, such as wind turbine blades, is even more complicated because of the need to capture the behavior of the composites accurately. Such simulations can be performed using Dassault Systemes' Abaqus technology, which not only provides Smoothed Particle Hydrodynamics for the ice impact simulations (this article) but also advanced composites simulation capabilities.
