Dassault Systemes Simulia tech helps Mahindra’s innovation factory to hit market faster

by Autocar Pro News Desk , 24 Nov 2020


Dassault Systemes has announced at the 3DEXPERIENCE Conference 2020 India on design, modelling and simulation that Mahindra & Mahindra has been delpoying its Simulia applications at Mahindra Research Valley (MRV), Tamil Nadu to meet safety regulations and emission norms, reduce costs, improve fuel efficiency, and achieve faster time to market of vehicles. 

Dassault says these applications include Simulia PowerFLOW Computational Fluid Dynamics (CFD) solutions, Simulia Abaqus Unified FEA and Simulia CST Studio Suite. Mahindra & Mahindra uses these solutions to transform its vehicle design process and improve efficiency across the product development lifecycle for its portfolio of passenger vehicles, farm and tractor division, and electric vehicles.

The Simulia suite offers a host of capabilities to perform part-level simulation and analysis like the suspension geometry being worked here; Abaqus Unified FEA used for powertrain development across OEMs.

Dassault Systemes says its Simulia applications enable engineers and R&D teams at MRV to enhance their engineering simulations and accurately predict real-world conditions. Teams can evaluate product performance and identify potential flaws, early in the design process prior to building physical prototypes. The applications are used to virtually validate vehicle performance, and optimise vehicle quality, durability and experience. With the performance trade-off analysis, simulation applications are helping MRV engineering and R&D teams to produce automobiles that are sustainable and meet global standards.

Sitarameswara Sarma Akella, vice-president- Automotive Sector, Mahindra & Mahindra said: “At MRV, for all our vehicles’ design, development and production, we are driven by the vision to get it ‘first time right and every time right’. Our long-term partner, Dassault Systemes, and a digital simulation-based approach are valuable in this regard, allowing for upfront simulation at the early-design stage when there is more flexibility for change. Further in the product development process, the realistic simulation solutions are used for virtual validation, giving us higher confidence before a regulatory test. Our R&D centers in India and the U.S. extensively used Dassault Systemes’ simulation technologies on the cloud, enabling remote collaboration on important projects during the pandemic.”

Deepak NG, MD – India, Dassault Systemes said: “Our relationship with Mahindra & Mahindra spans more than two decades. As a technology partner in design, engineering, simulation and manufacturing, we are excited to be part of their innovation journey in India and in their global markets. Our simulation portfolio helps our automotive customers align with regulatory norms like Bharat Stage Emission Standards (BSES) and Bharat New Vehicle Safety Assessment Program (BNVSAP) resulting in lower carbon footprint and a safer, more fuel-efficient product, all within ever-shrinking product development times.”

Simulia PowerFLOW CFD applications are used to accurately and efficiently perform aerodynamic, aeroacoustics and thermal management simulations. Using Simulia Abaqus Unified FEA, vehicle manufacturers can consider full vehicle loads, dynamic vibration, multibody systems, nonlinear static and thermal coupling for virtual testing. Simulia CST Studio Suite 3D electromagnetic analysis software is used to design, analyse and optimise EM components and systems. It facilitates EM analysis like performance and placement of antennas, exposure of the human body to EM fields, and EMI/EMC compliance that has become increasingly relevant.
