Two new optional premium modules available for intuitive 3D design software, adding new functionality to make the tool more powerful to support engineers in the rapid development of product concepts. SINGAPORE, 10 June, 2015 – RS Components (RS), the trading brand of Electrocomponents plc (LSE:ECM), the global distributor for engineers, today announced the expansion of DesignSpark Mechanical with two new optional premium modules that significantly extend the functionality of the existing version of the tool. Developed in conjunction with SpaceClaim, the leading provider of flexible and affordable 3D modelling software for engineers, DesignSpark Mechanical is an advanced 3D direct modelling tool that can be downloaded free of charge. Notwithstanding the availability of these optional premium paid-for modules, which can now be purchased from RS, very importantly the fundamental software that is available today will remain free to all users with continued support, new versions and updates from RS into the foreseeable future. DesignSpark Mechanical is a key element of the initiative by RS to provide tools for engineers that enable them to rapidly develop prototypes in the product concept design stage. For example, the software’s STL-output format enables the direct export of designs to 3D printers. The first premium module available is DesignSpark Mechanical Exchange, which adds advanced import/export capabilities and enables the import, modification and export of industry-standard STEP and IGES file formats, which allows full exchange of design data with CAD tools such as SolidWorks, Catia, ProEngineer and AutoCAD. The module can enable engineers to integrate DesignSpark Mechanical into a product development toolchain that works across various software platforms, moving beyond concept creation to a seamless workflow for producing final designs. It means that companies can pass designs to their mechanical department or outside contractors for final design creation and manufacturing and do not have to invest in […]

In the picture: Blue and green circles indicate iron (Fe) and selenium (Se) atoms, respectively. The superconducting transition temperature is tuned by introducing electrons by depositing potassium atoms (orange circles) on the surface. Yellow circles represent a pair of superconducting electrons (Cooper pair). A research group at Tohoku University has succeeded in fabricating an atomically thin, high-temperature superconductor film with a superconducting transition temperature (Tc) of up to 60 K (-213°C). The team, led by Prof. Takashi Takahashi (WPI-AIMR) and Asst. Prof. Kosuke Nakayama (Dept. of Physics), also established the method to control/tune the Tc. This finding not only provides an ideal platform for investigating the mechanism of superconductivity in the two-dimensional system, but also paves the way for the development of next-generation nano-scale superconducting devices. The research results were published in Nature Materials on June 1, 2015. Superconductors are regarded as one of the most promising candidates for next-generation advanced electronic devices, because the unique quantum effects in superconductors are a great advantage in achieving the energy-saving and ultrahigh-speed processing. However, the device application of superconductors has long been hindered. The largest obstacle is the necessity of a huge and expensive cooling system with liquid helium, because of the low Tc of conventional superconductors, which is close to absolute zero (0 K, – 273 °C)*1. It has also been a big challenge to realise the high-density integration of superconductors into electronic devices. In order to overcome these problems, it is definitely necessary to develop a new superconductor with higher- Tc, that can be fabricated into a thin film. The research team at Tohoku University turned its attention to iron selenide (FeSe), which is a member of iron-based superconductors*2. While the Tc of bulk FeSe is only 8 K (-265 °C), a signature of higher-Tc superconductivity has been suggested in ultrathin […]

Researchers in Hong Kong have developed a software platform designed to manage and control devices for “Internet of Things” (IoT) systems. The platform can be tailored for everything from city management sensors and devices to controlling home appliances. The Internet of Things (IoT) is an emerging technology in which smart devices are interconnected and communicate via the Internet. A limitless range of devices could be incorporated into the IoT, from refrigerators and TVs to cars and solar panels. However, there is currently no universal system for managing these devices and the data that is transferred between them. “Many vendors focus on device manufacturing and provide good technologies for wireless connectivity between devices,” explains Dr Billy Chan, senior manager of the Hong Kong Applied Science and Technology Research Institute (ASTRI). “But many existing systems lack an IoT management platform.” There is also no standard platform to leverage the development of IoT applications, which means that designers need to start from scratch with each new application. This is time consuming and costly. ASTRI has developed the “IoT Management and Application Platform” (IMAP), which allows the connection of a local network of devices to the Internet, and provides remote management of devices and data through a simple and customisable web-based graphical user interface. The system supports several technological standards for communication between devices, web interfaces and network architecture. This means it can be used on different platforms to support a diversity of devices and the development of IoT applications. To demonstrate IMAP’s capabilities, ASTRI has developed several “Smart City” applications. These include “Solar Street Light Management”, a system designed to provide real-time monitoring and remote control of more than 3,000 street lights in […]

Stuttgart – The large-scale project, known internally as PLM2015, has been completed and the new Siemens NX CAD software has been introduced. Key criteria to switch from the CATIA V5 design software, which had been used for many years, to Siemens NX, were the improvement of efficiency and sustainability – and the wish to integrate the product data management software currently used by Daimler, which forms the IT framework for all the development and product planning processes, with the CAD system. Dr Michael Gorriz, CIO Daimler: “I would like to thank all the people who have worked so hard to complete our biggest IT migration project in recent decades to the planned schedule. The introduction of the new design and product data software not only means that we are well prepared for the future. We have also taken the opportunity to bring our engineering processes in line with the highest standards in the automotive industry. Since 2012, more than 6,200 users throughout the company have received training. Some 33 role-based training modules were made available in German and English, and special courses were offered in Japanese, Portuguese, Spanish and Turkish. In peak periods, over 300 employees from the research and development office in Bangalore, India, were working on the migration of data from CATIA V5 to NX. In total, more than 235,000 CAD objects were migrated to the new software. All relevant suppliers either already use Siemens NX or have switched to Siemens NX in response to the software migration at Daimler. Close communication with all the relevant suppliers has safeguarded this important point in the supply chain. Daimler and Siemens will continue to work together closely on the further development of NX.

It has the ability to morph (change shape), propel itself and turn quickly in water (i.e. super-manoeuvrability) efficiently and silently, lending itself to future possibilities in surveillance and inspection. Scientists in Singapore have developed a new octopus-inspired robot which can zip through water 10 times its body length within one second, in an ultra-efficient manner. This first-ever ultra-fast propulsion and super-manoeuvrability demonstrated in underwater vehicles is unprecedented; and is the work of researchers and an engineer from the Singapore-MIT Alliance for Research and Technology (SMART). This ground-breaking research validates the physics of shape change (that forms the basis of jet propulsion of cephalopods) to give additional thrust to underwater vehicles. Inspired by the speed at which cephalopods like the octopus, flee from danger by inflating its mantle cavity with water to a bluff-body shape and then quickly expelling it to dart away, the researchers started building an octopus-inspired robot in November 2013. The end result is a polycarbonate 3D printed streamlined skeleton which had no moving parts and no energy storage device other than a thin elastic outer membrane. It works like blowing up a balloon and then releasing it to fly around the room. The 27cm long robot is inflated with water and once released, rapidly deflates by shooting the water out through an aperture at its base to power its propulsion. As the rocket contracts, it can achieve more than 2.6 times the thrust of a rigid rocket doing the same manoeuvre, while creating minimum turbulence – an important feature in underwater research / survey vehicles. The skeleton within the robot keeps the final shape streamlined, while fins at the tail, help in stabilisation. When a fish escapes by swimming fast, it bends its body and zooms through the water, losing some energy to the surrounding water and […]
