Why noise is one of the biggest problems with electric cars
By Steven Dom – Imagine your company is engineering the next line of electric vehicles. You create technical specifications that reduce range anxiety, you’ve perfected the colors that pop and entice customers to buy and with battery technology advancement, you’ve priced it right.
But there are problems with electric cars.
Because the electric vehicle engine emits no noise, pedestrians are more likely to be struck by an electric vehicle. A study by the National Highway Traffic Safety Administration indicated that hybrid and electric vehicles are 57 percent more likely to cause accidents with cyclists, and 37 percent more likely to cause an accident with pedestrians, than a standard internal combustion engine vehicle.
Countries are requiring the quietest cars emit a sound to warn those around the vehicle of its presence.
Now, imagine after creating the ideal electric vehicle, the customers reject it based on the noise it emits. What if your vehicle’s noise is too strange or annoying?
This is just one of the many perils facing the quiet electric vehicle.
The goal of successfully getting an electric vehicle to market, one that a consumer would be interested in and enjoying, was about improving range. In a world lacking in electric vehicle infrastructure, solving range anxiety would allow customers to feel more comfortable driving the electric vehicles to-and-from work and longer trips beyond.
Engineers focused on vehicle architecture including the number of motors driving the wheels, managing the HVAC system’s energy consumption and finding ways to reduce weight, such as using thinner panels and less sound deadening components to provide better mileage. Without the roar of a combustion engine, there was no need to reduce noise. more>

Tiny Vibration-Powered Robots Are the Size of the World’s Smallest Ant
By John Toon – Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these “micro-bristle-bots” might work together to sense environmental changes, move materials – or perhaps one day repair injuries inside the human body.
The prototype robots respond to different vibration frequencies depending on their configurations, allowing researchers to control individual bots by adjusting the vibration. Approximately two millimeters long – about the size of the world’s smallest ant – the bots can cover four times their own length in a second despite the physical limitations of their small size.
“We are working to make the technology robust, and we have a lot of potential applications in mind,” said Azadeh Ansari, an assistant professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. “We are working at the intersection of mechanics, electronics, biology and physics. It’s a very rich area and there’s a lot of room for multidisciplinary concepts.”
A paper describing the micro-bristle-bots has been accepted for publication in the Journal of Micromechanics and Microengineering. The research was supported by a seed grant from Georgia Tech’s Institute for Electronics and Nanotechnology. In addition to Ansari, the research team includes George W. Woodruff School of Mechanical Engineering Associate Professor Jun Ueda and graduate students DeaGyu Kim and Zhijian (Chris) Hao. more>

Paragon VTOL Aerospace adopts solutions from Siemens to streamline next-generation design
By Alisa Coffey – The need for increased performance and reduced time-to-market has led Paragon VTOL Aerospace, a global vertical take-off and landing (VTOL) aircraft provider for numerous industries, to adopt solutions from Siemens Digital Industries Software through its product development process. Paragon produces industry-specific drone hardware ranging from security applications for agricultural theft and commuter law adherence to human passenger drones.
Paragon is also partnering with Aerotropolis Jamaica, a national project spearheaded by the Hon. L. Michael Henry in the Office of the Prime Minister, to build an ecosystem for Urban Air Mobility (UAM). The company plans to achieve positive results by reducing time and cost of its product development and testing through implementation of key technology from Siemens.
“Our vision is to provide a portfolio of intellectual property, industry specific drones, human passenger drones, and virtual highway platforms in Jamaica,” said Paragon VTOL founder and oil executive Dwight Smith, a native Jamaican and American citizen. “We currently have plans to implement software and hardware programs in 2019 and begin testing their two to four passenger drones by year-end 2019.”
Paragon has been developing their platform and much of the technology through collaboration with Siemens, major American universities, Silicon Valley experts, and ex-military personnel. Siemens is providing an integrated set of software solutions including STAR-CCM+, Simcenter, and NX for Paragon to design, test, produce, and monitor its extensive range of drone systems. more>

Digitalize battery manufacturing for a greener future with electric vehicles
By Vincent Guo – The electrification of automobiles is gaining momentum globally as many countries have laid out plans to prohibit the sales of internal combustion engine (ICE) cars. The closing deadline is 2025 for the Netherlands and Norway, with Germany and India to be the next down the line in 2030, followed by UK and France in 2040. Other major economies in the world provide aggressive initiatives to push the electric vehicle (EV) to the market. For example, USA, China, Norway, Denmark, and South Korea have been implementing cash subsidiaries to EV buyers over $10,000 per vehicle, with Denmark and South Korea paying the consumer almost 20,000 Euro for each car purchased.
These incentive plans, however, also indicate that the price of EV is still high comparing to traditional cars. Independent research shows that the cost of the electrical powertrain is roughly 50% of the EV while, while the cost of the powertrain for ICE cars is only 16%. While it is largely true that the components of a car, whether it is an EV or ICE car, are largely similar except for the powertrain, the source of the difference in total cost is obviously the powertrain. The most expensive component is the battery pack, which accounts for roughly half of the powertrain and a quarter of the entire car.
Fortunately, the cost of the battery is going down steadily in the past 10 years. It is about to hit the point that the total cost of an EV is competitive to an ICE car and the point is about 125-150 USD/kWh.
As a result, battery manufacturing capacity has been ramping up quickly. Tesla is leading the way by its Gigafacotry in Nevada with target annual capacity of 35 GWh. Yet the race is tight as the battery manufacturing in Asia is catching up. CATL of China had recently announced a plan to boost its capacity in Germany to 100 GWh. more>

BAR Technologies uses Siemens Digital Industries Software solutions to create a new class of sport yacht
Siemens – With an optimized hull and dynamically adjusting foils that enable greater efficiency over a wider range of speeds, it’s a boat designed for both performance and comfort. The Princess Yachts R35 was made possible by BAR Technologies, which uses highly specialized techniques and processes when designing an America’s Cup racing yacht. BAR Technologies is now offering its unique expertise to customers across the marine industry.
Princess Yachts first approached BAR Technologies with the aim of creating a completely new design that would attract people who had not previously considered buying a boat. The new design was to be an entry-level purchase: a day boat that was exciting yet easy to drive. Paul Mackenzie, director of product development at Princess Yachts, explains: “We have a very high percentage of return customers and once they are in the Princess family they tend to move up our range, so introductory boats have always been important. However, most people who buy a Princess are already boat enthusiasts. We were looking to expand our potential market, closing the gap between boat owner and car owner, with a product that could be positioned alongside a super car.”
Simon Schofield, chief technology officer at BAR Technologies, adds “Our brief was to devise a technically driven design with increased efficiency and accessible performance, yet retain the luxury and quality that Princess is known for. The digital modeling and simulation tools and techniques that we have established over several years were critical to the fulfillment of the brief.”
The integrated virtual environment at BAR Technologies uses solutions from Siemens Digital Industries Software. These include NX™ software for product design,Teamcenter® software for data management and the Simcenter™ software portfolio, which includes Simcenter™ Nastran® for engineering analysis and Simcenter STAR-CCM+® software for computational fluid dynamics (CFD) analysis. more>

I Can Get Paid for Bike Helmet Art?!
By Jordan Kushins – There’s so much freedom to be found on a bike: hop on, start pedaling, and go go go. But before setting out, adults have an important decision to make: to helmet or not to helmet. Danny Sun understands that despite the fact that strapping one on can literally save your life, helmets can be a tough sell for adults. “I know I work on a product that no one really wants to wear,” he says.
Sun is an art director at Bell, a longtime leader in the motorcycle and bicycle helmet field. He and senior designer Anne Mark have been adorning bike helmets—specifically, “mid-price-point helmets for average everyday riders,” she says—with colors, graphics, finishes, and more for more than a decade. They regularly collaborate with companies such as Disney, Lucasfilm, and Marvel, and produce custom lines for major big-box clients. The full-time job of a helmet designer requires far more than digital creative skills; here’s what it takes to make it in the challenging, curvilinear world of helmet art.
Personal reasons for going without headgear varies, but often, it’s an image thing. “There’s a whole generation who feel like helmets are really dorky,” says Sun.
In the quest to get as many riders as possible opting in, helmet designers have got to offer options that cater to that wide range of potential customers. It’s about finding a balance, but also pushing the boundaries a bit on what might spark a potential purchase—but also joy. more>
