In this blog series, we hear directly from individual SIMULIA Champions about their own personal simulation story. This post from Robert Luo of Trelleborg AVS is a continuation in the series, where he talks about how he turned a lifelong dream of being an engineer into a reality. Robert also tells us how proud he is to be a SIMULIA Champion because of the success he’s achieved in both academic and engineering applications. A Dream Job My dream was always to become an engineering educator, someone who designs wonderful products but also a teacher who passes knowledge on to the next ge ..read more

In the quest to design more efficient and sustainable aircraft, the turbofan engine provides an elegant solution. Using a fan to draw in extra air, which helps propel the aircraft, these engines provide thrust and boost fuel efficiency. While turbofan are generally quieter than turbojets, the engine is still a main contributor to community noise at takeoff and on landing. “Noise matters because of its community impact,” said Sheryl Grace, associate professor of mechanical engineering at Boston University. “If you are going to take off or land at an airport, fuel consumption is a secondary conc ..read more

Train aerodynamics has a significant impact on energy efficiency and fuel consumption. Computational fluid dynamics (CFD) simulation (PowerFLOW) allows engineers to design trains to minimize air resistance, and to analyze aerodynamics long before wind tunnel testing. The railway industry was one of the first to realize the importance of aerodynamics and drag. In the 1930s, iconic “Streamliner” locomotives such as the American Pioneer Zephyr, British Mallard and German Flying Hamburger reached speeds well in excess of 100 mph thanks in large part to their sleek designs, which reduced drag. Late ..read more

Simulation allows tire engineers to maximize the sustainability of their products and ensure tires meet all specifications. Leading companies are using simulation to find the best trade-off between wear, fuel efficiency and grip on the magic triangle; to design smart connected tires that enable automatic wear monitoring and Tire as a Service (TaaS); and to manage the growing complexity of their product ranges through modular tire design. How Tires Can Cause Air Pollution When we think about pollution from cars, we usually think of the tailpipe emissions. But there’s another source of pollution ..read more

We see more foldable screens appearing in the market for smartphones and larger devices. Designers face new types of challenges because foldable displays are typically built with multiple, flexible functional layers, bonded with optically clear adhesives (OCAs). Any of the individual functional layers can fail, either by plastic deformation, or cracking, including the cover glass. Damage to the electrical structures within each layer can also occur. In addition, each of those layers is bonded together with OCAs which can de-bond or de-laminate, creating an opaque area in the display, as was se ..read more

There is increasing demand for industrial gear units with higher efficiency, lower noise and longer life. Suppliers are pushed to design equipment to reduce operational costs and capital expenditure. The system efficiency of industrial gear units is estimated through the evaluation of power losses, which can be split into load-dependent and no-load dependent losses. Whereas load-dependent gear power losses arise from gears and bearings when torque is transferred, no-load losses are a consequence of the gearbox components experiencing drag in the lubricant.  Lubrication simulation of a 5MW ..read more

By Matthias Meienhofer, SIMULIA Brand Sales ASEAN and ANZ, Dassault Systèmes Developing products is a highly complex task that involves multiple departments, stakeholders, and tools. A large amount of information and data needs to be exchanged, and it can take weeks or up to months to arrive at initial designs. Traditionally, companies adhere to a “linear approach” for product development. Once CAD data is created, it is passed on for geometry clean up. From there it is moved to meshing and thereafter again passed on for simulation and analysis. If along the way an issue emerges, the progress ..read more

Not many five-year-olds would accurately foresee the beginning of their career, but this was undoubtedly the case for Francesco Avallone, Professor at Politecnico di Torino. “In my first year of school I was asked what I wanted to do in the future and I remember saying that I wanted to be an aerospace engineer,” Avallone said. “At that time, I can’t imagine that I knew what that meant, but the fact remains that I was drawn to engineering – and anything involving math problems, to be honest – from an incredibly young age.” About 24 years later, Avallone was graduating from the University of Nap ..read more

Cylinder Damage How do composite materials relate to you and me? A composite material is made of two or more materials. One is a binder material that holds everything together. The others are stronger materials that act as reinforcement such as woven fiber. Composite materials have many advantages compared to traditional homogeneous materials such as metal: they have higher strength to weight ratio, which is desirable in aircraft design for fuel cost saving, they have better corrosion resistance and durability. They are also easier for engineers to tailor and optimize. Composite materials are ..read more

In this new blog series, we hear directly from individual SIMULIA Champions about their own personal simulation story. This post from John Sawyer of Atkins Engineering is a continuation in the series, where he talks about how his love of horse riding is similar to problems he faces in his engineering career. John also tells us how much he enjoys being a SIMULIA Champion because of the sense of community and how it brings engineers together to solve problems. Check out John’s presentation on structures simplification from the 2022 EuroNorth RUM. Also, don’t forget you can connect with all ..read more
