Is e-bike noise an issue? Quit whining! Spring is here and summer is coming! So after spending (part of) my winter holidays analyzing the vibrations on a snowboard (and proving why it’s better than skiing, check here!), I’ve decided to take out my e-bike for a ride. Another good reason to do so, is the fact that today – June 3 – is World Bicycle Day. E-bike sounds E-bikes become
Combine solution speed and accuracy for axisymmetric rotor dynamics In a previous blog, we explained how centrifugal loads may lead to high levels of vibration (and even system instability) when a rotating structure is not axisymmetric. We also gave some examples of situations that could be life-threatening. But in fact, you’ve all seen this phenomenon in
Reacting Flows and Combustion Computational Fluid Dynamics (CFD) with Simcenter STAR-CCM+ The wide range of reacting flows Reacting Flows and Combustion CFD with Simcenter STAR-CCM+ 20 Reacting Flows are all around us. Therefore, it’s no surprise that applications that rely on chemical reactions and combustion are spread across almost all industries. Gas turbines play and will
Simcenter 3D Efficient and accurate acoustic trim modeling Lighter. More efficient. Electrified. Those are the key aspirations of almost every car manufacturer today. The urgent necessity to reduce our carbon footprint is leading to a burst of innovation. New materials and manufacturing methods as well as complex multiphysics technologies grab all the attention. They radically
Reach an optimal heavy equipment thermal management using 1D/3D co-simulation Regardless of harsh conditions (temperature variation and dirty environment), operators from the agricultural, mining and construction fields always rely on their heavy equipment to accomplish their work. To reduce downtime and safety risks, powertrain management systems must be robust in both high and cold temperature
Design For Purpose: Virtual Simulation and Testing Welcome back! Thank you for your continued interest in how additive processes can radically decrease manufacturing’s sustainable footprint. In the first article, we covered NX lattice structure capabilities for enhanced designs. In the second article, we covered the incorporation of Multimech to accelerate the product development lifecycle by
Simcenter Amesim: The 10 most crazy System Simulations Inspired by Simon Fischer and its “10 secrets to a stunningly fun CFD simulation“, we decided to explore our Simcenter Amesim archives and extract the most exotic, weird, funny, yet useful simulations we ever did! You might ask yourself: “Why did they even spend time on this?” or “How
Simcenter 3D Defeature and mid surface geometry quickly One of the main issues you face as an analyst is the need to clean, defeature, and mid-surface geometry you import from CAD. Features like small holes, small steps, and surfaces impact meshing speed and quality but can be irrelevant to engineering performance. You might also have
Industrial Challenge: Materials Engineering for Composites subject to Variability The powerful combination of being strong and lightweight makes composites materials favorable for the automotive and aerospace industry. This low weight translates into a reduction in fuel consumption and emission. Composite materials are more complex than metals, with more design parameters. A robust design is desired,
The electric vehicle inverter is an essential organ of the powertrain, yet it is often overlooked compared to batteries or electric machines. Looking at this study from NAS (2010), it is the most expensive PHEV component, second only to the battery. Based on this, it must be carefully engineered. This is what is described in
