Regulations such as Corporate Average Fuel Economy (CAFE), new emission norms, etc are forcing auto makers in India to accelerate research and capability improvement activities. Simulation is helping automotive OEMs and suppliers to enhance the speed of technology development to meet these norms, says Rafiq Somani, Area VP, South Asia Pacific and Middle East, ANSYS - a leading global player that provides engineering simulation software. He says there is a rise in usage of engineering simulation among SMEs in India as product development and manufacturing is shifting to SMEs with OEMs becoming more like system integrators. In conversation with Rakesh Rao, Rafiq Somani stresses on the importance of simulation and its impact on emerging trends such as electro-mobility, autonomous vehicles, additive manufacturing, etc.
ANSYS’ mission is to empower our customers to design and deliver transformational products using ANSYS Simulation solutions. Using simulation, companies can verify the product behaviour against customer requirements during the concept stage itself, even before CAD is made. They can optimise the product performance and robustness during the design stage, use digital twin of the real asset to perform conditioned based maintenance, estimate the remaining useful life etc. during operation stage.
Thus, simulation has become pervasive across product life cycle.
India is a signatory of Paris Climate Change Agreement and has set ambitious targets for non-fossil fuel emissions. India’s commitment to advancing emission norms – from BS IV to BS VI norms by 2020 – will push OEMs to invest more in e-mobility, meaning electrical/hybrid powertrains, including batteries, as well as in lightweight and aerodynamic drag-reducing technologies.
In the AM process, a digital data file is transmitted to a production machine, which ultimately translates an engineering design into a 3D-printed part. Initially, AM was utilised as a rapid prototyping method - an accelerated method to create (mostly plastic) parts before manufacturing by well-accepted methodologies, such as injection moulding, casting, forming, joining, etc.
Metal-based AM processes were developed in the 1990s and then several companies launched laser sintering systems that could 3D print metal parts directly, thus providing an alternative to direct, multi-stage manufacturing processes. Selective laser sintering (SLS) is an AM technique that uses a laser as the energy source to melt powder (metal or polymer). The laser targets points in space defined by a 3D model, and binds the powder material together to create a solid structure.
ANSYS helps them in the design process by estimating residual stresses and distortions that occur during the additive manufacturing process. The major role that ANSYS has played is not just in producing tools but in ensuring that our customers know how to use them effectively to their best advantage.
Manufacturing is becoming the key focus point for all global economies. With manufacturing’s significant contribution to a country's GDP and a rapidly expanding consumer market, policy makers around the globe realise that a strong manufacturing footprint has become a strategic necessity for growth. Because of a strong push from governments, the manufacturing industry is set to undergo a wave of transformation in the coming years, aided by the influx of commercial information and communication technologies. One of the key catalysts aiding this transformation is the Internet of Things (IoT), which is set to re-invent every entity in the manufacturing value chain.
The IoT for industries will empower new ways of ideation, engineering innovation, production execution and service excellence. Although the impact of the IoT is expected to pervade all elements of manufacturing, its effect in the initial phase of product conception is expected to be particularly significant.
