ABAQUS: A Complete Solution for Realistic Simulation

A myriad of products have been changing and improving the facet of our lives, be it machines, vehicles, life sciences. The way products are engineered has been changing recently, being more human-centric. Vehicles are engineered to give optimal driving experience, autonomous vehicles that drive by themselves giving the owner the luxury and comfort, there are many wearable devices being engineered to monitor health etc. To achieve this, a lot of non-destructive testing needs to be done which is achieved very efficiently through virtual simulations. Dassault Systemes’ SIMULIA, a step ahead in virtual analysis, offers the virtual simulation landscape with a variety of simulation and optimisation software like Abaqus, Fe-Safe, I-sight etc. SIMULIA provides a multitude of multidisciplinary, multi-scale simulation applications for various industries such as Aerospace and Defence, Transportation and Mobility, Life-sciences, High tech, Energy and Materials, Industrial Equipment, Heavy engineering etc.

  4. Abaqus/CFD provides advanced computational fluid dynamics capabilities with extensive support for pre- and post-processing provided in Abaqus/CAE. These scalable parallel CFD simulation capabilities address a broad range of nonlinear coupled fluid-thermal and fluid-structural problems.
  5. For implicit and explicit analysis, Abaqus has it all integrated. You can switch from explicit/implicit between analysis steps.
  6. Abaqus CAE GUI is very user-friendly, and the user can model a problem in a real – virtual manner.
  7. Abaqus can be used for both linear and non-linear analysis.

A Technology Perspective on Occupant Ergonomics In Automotive Industry

The Automotive Industry is witnessing a transformation globally as well as in India. New technologies and government regulations are driving this transformation. More so, the Indian customers and their expectations from an automobile is changing notwithstanding the onslaught of shared and hired mobility service providers. It is imperative that Indian Automotive Industry takes cognizant of this and many of them already are. The consumer seeks a delightful experience from driving an automotive – be it shared or hired. The mileage and quality aspects are taken for granted while making a buying decision today.
Ergonomics is one of the areas which can bring a lot of experiential delight as well as adherence to safety norms. As norms become stringent and consumer preferences change to more personalization and comfort, many Automotive companies and component manufacturers are beginning to ensure that the products they manufacture are suited for the Indian demography. It is also important that they have the necessary technology platforms to do this. This article sums up the importance of Ergonomics and how Automotive Manufacturers can leverage technology platforms to ensure its compliance not only for the Indian market but also for the global market.

What is Automotive Ergonomics and its importance to the Indian Automotive Industry?
Ergonomics is the science that applies theories, principles, data and methods eds blog 2 to product design, with the goal to optimize user comfort, health and safety, as well as overall system performance. Automotive ergonomics is the study of how an automotive can be designed better for human use.
India is a strong and emerging market for automotive companies. It is also becoming a hub for global R&D as well as manufacturing. The automotive industry is very mature in terms of adoption of Digital Product Design and Validation. With this background, extending product design to Occupant Ergonomics is very easy with right technologies at your disposal.

Ergonomics Simulation – Doing it digitally

EDS Technologies in partnership with Human Solutions has offered technology platforms to many Indian Automotive companies for ergonomics simulation. Using 3D body scanners from Human Solutions, ARAI has created the first comprehensive database for the Indian population which can be utilized by Automotive companies.

RAMSIS is the de-facto standard worldwide in Automotive Industry in Occupant Ergonomics Simulation for interior vehicle design. RAMSIS was developed by Human Solutions and a consortium consisting of all German car manufacturers and two seat manufacturers in the 1980s. Today, more than 70% of the world’s car manufacturers use RAMSIS. Development of RAMSIS is still heavily supported by the German consortium and new developments and functions are in most cases based on input from automotive customers.

Screenshot 2018-12-18 at 3.22.20 PMThe use of RAMSIS in the design process increases the ergonomics quality of products and makes ergonomics an integral part of the design process. It allows manufacturers to put the end-user in the center of the development process and build the product that will offer a safe and comfortable environment to the targeted end-user population. From the earliest stage of the design process, until the final layout of the instrument panel, RAMSIS provides the methods, data and information to make well-founded, optimal design decisions from an ergonomic point of view.

Automotive companies have realized the following benefits from RAMSIS in terms of
ergonomics and efficiency:

  • Faster time-to-market thanks to savings on time-consuming trial runs with test persons
  • Reduction in development costs of more than 50%
  • Detailed Statistical Knowledge about body dimensions and about ingress and egress
  • Realistic Predictions about future space and operation conditions inside a vehicle
  • Compliance with standards and ensuring of ergonomic quality such as the best accessibility and usability of all controls
  • Faster, enhanced product maturity and cost savings through the avoidance of planning errors
  • Virtual, International test collective to represent human size differences
  • Comparison of various vehicle concepts with the same test collective
  • Simulation of driver’s posture and motion behavior based on modern research
  • Effective integration into your product development process
  • Competitive advantages thanks to high level of comfort and safety

Traditionally, automobiles manufacturers from Europe, North America, South Korea or Japan were sold as it is or homologated with very little change from ergonomics perspective. Indian based OEMs also were also more focused on mileage. India has a very different demography when compared to these countries. It is important that products are designed and manufactured for Indian demography when the indented users are Indians.

Realistic Simulation Supports Expansion of the London Underground

Dubbed “one of the most complex tunneling projects in the U.K.,” the Bond Street Station Upgrade (BSSU) project is being carried out to satisfy growing traffic demands within London’s busiest shopping district, the West End.

Upon its completion, Bond Street Station’s daily passenger numbers are expected to rise from 155,000 to 225,000.

A project this complex in nature has to consider the existing tunnel infrastructure, as well as the stress and strains imposed by the surrounding soil layers for the development of new tunnels.

Dr. Sauer and Partners was contracted to provide such tunneling expertise. The company took on responsibility for preliminary-to-detailed design and

Using FEA simulation, they were able to virtually test the ground through which the tunnels are being dug alongside the existing tunnel structures.

This realistic assessment enabled them to improve upon the preliminary design, as well as bring greater confidence to the overall approval process.

To learn more, read the case study, “Tunnel Vision” to see how realistic simulation plays an important role in tunnel excavation.

We also encourage you to download the whitepaper by Ali Nasekhian, Sr. Tunnel/Geotechnical engineer at Dr. Sauer and Partners, which highlights the merits and shortcomings of large 3D models in tunneling.
