Using Simcenter Amesim™ software, Simcenter Engineering experts and Honda set out to develop a new prediction technique and a new evaluation method for engine restart vibrations. Honda can now accurately predict the entire powertrain restart process, beginning with the vehicle controls signals causing a certain in-cylinder pressure, which then results into driveline torque, particular suspension and powertrain bushing interface forces and eventually body vibration shock.
One of these startups is Karma Automotive, a California-based carmaker that rose from the ashes (or rather assets) of Fisker Automotive in 2014. In the resurrection process, Karma managed to preserve the good and overcome the bad: they retained the beautiful Italian design of their cars, which held a lot of appeal to their customers, but significantly upgraded the technology. The result is a luxury electric hybrid sedan that maintains much of the original exterior and interior of the Fisker Karma, but incorporates an A123 battery, charger and electrical controls. It is “the car you drive when you want to be seen,” says Bob Kruse, chief technical officer of Karma Automotive.
The world’s largest and most powerful space science telescope is finally scheduled for launch, on Christmas Eve. The James Webb Space Telescope (JWST) has been in the works for decades, and its gold-plated, 21-foot mirror is capable of exploring much farther out into space than its predecessor, the famous Hubble Space Telescope. After many delays and years of waiting, for many, it seems almost unbelievable that it’s finally about to happen.
The same applies for durability engineers. Technology evolves so quickly that holding on to traditional processes and methodologies actually equals standing still. I hear you thinking: “I’m doing well, my business is stable.” But can you keep up? Your customers are getting more demanding, and your competitors are always close. It requires an effort to keep moving forward, innovate, and search new solutions or methodologies. But it pays off!
Today, vehicle electrification represents one of the major pillars to help reduce the overall greenhouse gas emissions from human activity. From the early days, there’s been a lot of effort to reduce the overall cost of the battery pack and increase its energy density. Above all, this was essential to offer commercially competitive electric vehicles (xEVs), compared to conventional internal combustion engine (ICE)-based vehicles. It was critical to reduce the consumer’s range anxiety, or in simple terms, remove the fear of being flat in the middle of the Mojave Desert.
Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter. Our own sun is 75% Hydrogen and 25% helium. Hydrogen is about three times as energy-dense as natural gas (which is principally methane) and more than twice as energy-dense as gasoline. Burning hydrogen is much cleaner than burning hydrocarbons. When mixed with pure oxygen it only produces water as a by-product of combustion.
Mobility electrification is not a trend. It is a fact. Most OEMs are already planning the retirement of their combustion-engine fleets. But with electrification we generally associate Li-ion batteries and a lot of inherent challenges. Rare materials, range anxiety, lack of charging stations, battery safety, poor recycling possibilities are some of them. Although extensive research is being conducted to solve these challenges, an alternative is being considered: hydrogen fuel cell vehicles. In this article we discuss how simulation can help OEMs & suppliers virtually design and certify the composite pressure vessel used for hydrogen storage.
The engineers at engineering consultancy R&D CFD are accustomed to applying CFD simulation to the challenges of Internal Combustion Engine (ICE) design. A recent project called on them to apply their analysis techniques to a different type of “ICE”--ICE cream. Their approach, however, was the same—using Simcenter STAR-CCM+ Multiphysics CFD software allowed the engineers to simulate 2000 variegator design variants in 17 days, and then optimize the design of the feeding chamber to guarantee that the final product would have the desired home-made, variegated appearance each time.
Vehicle performance is the study of the motion of a vehicle. The motion of any vehicle depends upon all the forces and moments that act upon it. These forces and moments, for the most part are caused by interaction of the vehicle with the surrounding medium(s) such as air or water (e.g. fluid static and dynamic forces), gravitational attraction (gravity forces), Earth’s surface (support, ground, or landing gear forces), and on-board energy consuming devices such as rocket, turbojet, piston engine and propellers (propulsion forces). Consequently, in order to fully understand the performance problem, it is necessary to study and, in some way, characterize these interacting forces.
Disruption in the Automotive and Transportation industry is well under way. How we get from Point A to Point B is being reinvented due to increasing urbanization. This is driving the convergence of autonomous, electrification, connectivity and shared transportation systems rapidly. Auto OEMs and suppliers have to develop and execute new business models to prevent becoming obsolete as these mega trends unfold and technology innovation increases exponentially. The race is on for Auto OEM’s and suppliers to transform their business and provide multimodal mobility services for the future of mobility.
As vehicles become more automated with advanced driver assistance systems (ADAS), development and validation testing conditions need to be defined. Which scenarios should be considered for ADAS and future autonomous vehicles (AVs)? How can a large number of potential driving situations be considered and how can the most critical ones be identified? Can verification and validation (V&V) be managed in a realistic timeframe and at an acceptable cost? This blog post highlights a process applied during vehicle development, and discusses the support Siemens Digital Industries Software and ETS Solutions Asia engineering services team can provide.
Acoustics is the study of sound, noise, and vibration. Understanding the acoustical performance of your product is important because different types of devices have different thresholds for acceptable amounts of acoustic noise. Acoustic testing services assess how your product will perform in real-world conditions, and whether or not further revisions should be made to reduce noise. Acoustical testing helps product manufacturers from various industries determine these values.
ETS Solutions Asia is a leading provider of technologies, consultancy, products and services in various sectors, including industry solutions from Siemens Digital Industries Software. Specializing in Simulation & Test, we help companies establish a competitive advantage by optimizing their processes, from planning and development through manufacturing, production and support.
By its nature, an Industry 4.0 implementation will be incremental, not big bang. Manufacturing will still need people and centralized information applications in addition to the new IIoT data for the next several decades. That’s where the systems that manage all that data, and the people, processes, products and machines that generate it – manufacturing operations management (MOM), or the next evolution of manufacturing execution systems (MES) – will play a critical role.
Noise and vibration are both dynamic processes and have a close physical relationship. Vibrating systems make noise, and noise makes structural systems vibrate. Both noise and vibration are adversely affecting people and if sufficiently intense, both noise and vibration can permanently hurt people. At the same time, also structural systems, if excited by excessive noise and vibration over sufficient periods of time, can fatigue and fail.

Every human being is innately different and so is our cough. 7.5 billion people. 7.5 billion different coughs. There’s been plenty of research into the human cough. Enough, in fact, to tell us what an average cough from an adult should look like. It’s this average cough that’ll help us uncover some key insights behind how cough droplets travel and move in an aircraft cabin.

In the case of the power adapters that NXP Semiconductors’ Smart Power Division are developing thermal considerations have really come to the fore, driven by the trends we see in mobile power adaptors, which are getting smaller and have a higher output power. Thermal limits are now constraining all aspects of the design.
