CAD/SOFTWARE PRODUCTS VIBRATION-SPECIFIC FATIGUE SOFTWARE
According to Altair Partner Alliance (APA), CAEfatigue VIBRATION, a frequency-based fatigue solver and random response post processor developed by CAEfatigue, is available to HyperWorks users for download.
This essentially comprises
two products in one: a powerful random response post processor for the frequency domain; and a vibration fatigue solver. It works with mixed random and deterministic loading sources, a process not previously available, to provide fatigue life and damage predictions, as well as several forms of response statistics that were not possible before this code. It is said to be exceptionally fast,
ANSYS 16.0 INTRODUCED
ANSYS 16.0 has been introduced, offering advanced functionality that enables engineers to rapidly innovate new products. According to the company, this delivers major advancements across the company’s entire portfolio, including structures, fluids, electronics and systems engineering solutions – providing engineers with the ability to validate complete virtual prototypes. Highlights of the release include
capabilities to verify electronics reliability and performance throughout the design process and complex electronics industry supply chains. In addition, the company is introducing the ANSYS Electronics Desktop, a single- window, highly integrated interface that brings electromagnetic, circuit and systems analysis into a seamless working environment to maximize productivity and to ensure users are following simulation best practices. Another new feature is the ability to create 3D components and integrate them into larger electronic assemblies, an approach that can facilitate the creation of wireless communication systems. Simulation-ready 3D components are created and stored in library files that can be added to larger system designs. Also provided is new functionality for
composite designs; advanced solutions for elastomers like rubber; and it reduces fluid dynamics preprocessing time for complex models by up to 40%.

easy-to-use and capable of handling particularly large models. The CAEfatigue VIBRATION
random response tool contains a wide array of capabilities, including
damage/life calculations for components subjected to single or multiple random vibration load inputs. Deterministic loads can easily be mixed with random and static offsets to create complex load inputs. These capabilities are widely applicable across most industries, with major opportunities in the automotive and aerospace industries. The full functionality of
calculation of response statistics such as stress peaks, strain peaks and stress and strain root mean square (RMS), the latter of which includes the elastic and plastic components estimated using stress-strain material properties. The fatigue tool provides fatigue
CAEfatigue VIBRATION is available through the APA, which includes the Random Response, Random Only Fatigue, Full Fatigue and Multiple Random Loads modules.

As an expert in Finite Element Analysis (FEA), Blue Diamond has produced a short video to show how it can be used to aid design and to minimise the need for experimental testing. FEA allows the user to predict and
improve product performance and reliability, make physical prototyping more accurate, evaluate different designs and materials, and reduce material usage and cost. The effects of wear can be assessed in a virtual environment as can the application of constraints such as pressure and temperature. The video is on YouTube –enter

RS Components (RS) and Allied Electronics (Allied) have launched a new version of DesignSpark Mechanical, the fully featured 3D Concept Modelling and design tool. DesignSpark Mechanical is available for free download at
www.rs-online.com/designspark/electronics/eng/page/mechanical. DesignSpark Mechanical has been developed in conjunction
with SpaceClaim, a provider of 3D modelling software for engineers. Together with the DesignSpark PCB design tool, it is a key element in RS and Allied’s initiative to provide tools for engineers that enable them to rapidly develop prototypes in the innovation and product concept design stage. An important element of DesignSpark Mechanical is its STL-output format, which allows the direct export of designs to 3D printers. In response to user requests, Version 2.0 of the software has a number of new features that enable an even better user experience. The tool’s new simplified user interface includes built-in help text and Quick Guide tutorials, example designs, and also makes its BOM-quote functionality even easier to find and use. The tool also provides access to a new 3D catalogue allowing the rapid insertion of tens of thousands of 3D models from leading component manufacturers, as well as the integration of all the necessary RS and Allied purchasing data for fast Bill-of Materials (BOM) creation. In addition, a ‘quick parts’ 3D printing service is now integrated into the tool, which is available via RS and Allied in conjunction with its partner 3D Systems.

New from Maplesoft is the MapleSim Battery Library, an add-on component library for its advanced system- level modelling tool. This allows engineers to incorporate physics-based predictive models of battery cells into their multidomain models so they can take battery behaviour into account early in the design process. With this information, engineers can optimise battery and system performance, and reduce the risk of
undesirable effects such as battery overheating, the company explains. The MapleSim Battery Library supports both equivalent circuit and electrochemical battery models, and
includes parameter identification tools for determining model parameters from experimental data. It can be used in any modelling project that involves batteries, including consumer electronics, electric and
hybrid-electric vehicles, power electronics, and energy storage in power generation applications. Typical projects include battery load analysis and optimization to maximize the time between charges; hardware-in- the-loop testing of Battery Management Systems; thermal modelling and cooling system optimization to stabilize battery temperature; and State of Health effects on charge/discharge efficiency and thermal runaway.
