For its first datacenter in Prineville, Oregon, Facebook set out to significantly improve its power efficiency, cost, reliability, serviceability and environmental footprint. To this end, a holistic approach was used to redesign many dimensions of the datacenter and servers. This white paper1 focuses on the Facebook server design, combining aspects of power, motherboard, thermal and mechanical design.
More than just a CFD code, STAR-CCM+ is a complete multiphysics toolbox, able to solve flow, thermal and stress problems involving multiple phases. From liquid jets, to water ingression, STAR-CCM+ allows you to simulate any cooling strategy that you can define and even the effect of what happens when those strategies go wrong.
The first is a hybrid approach, integrating test and simulation for realistic road-load prediction, even for loads that cannot be measured. And the second is a digital road approach, running a comprehensive virtual model on a digital track when test data is unavailable. Additionally, it considers new emerging technologies, such as composites and additive manufacturing.
ETS I Series Vibration Testing System with force rating from 4,000 to 16,000 kgf is ideal for screening of medium sized assemblies with extreme high acceleration test level and high frequency range. The Extreme Acceleration Shaker Y-Ring (EAS-Y Ring) armature is a revolutionary design which will allow for using a proportioned head expander to test multiple specimens simultaneously at extreme high acceleration level.
Products are vibration tested to determine limits and tolerances. Every product is vulnerable to vibration loads and potential breakage or failure. That includes tiny objects like microprocessors and circuit boards right up to giant structures like bridges and skyscrapers. Testing through vibrations ensures the product is qualified for its intended purpose and meets safety and regulatory standards, as well as complies with any International Standards Organization (ISO) requirements.
Additive manufacturing (AM) is changing the way products are made. New revolutionary machines and processes are rapidly pushing AM from the prototype environment onto the production floor. The additive manufacturing capabilities in Simcenter 3D software are used to predict distortions and defects before parts are printed, thereby reducing the number of test prints and improving the quality of the final print.
For your vibration qualification tests, the unique combination of Simcenter SCADAS™ hardware, Simcenter Testlab™ software and ETS Solutions expertise in vibration testing, delivers outstanding performance for all standard and advanced testing requirements. This includes tests based on tailored profiles, interfaces with test cells or climatic chambers, and tests based on newer techniques such as the military standard (MIL-STD) 527 method.
Simcenter 3D software offers a distinctive suite of tools to support fatigue design in all stages of development. This includes easy-to-use wizards for strength and fatigue in the design phase, fatigue information on the current simulated part, detailed analysis of complex load scenarios, including weldments and connections, and new materials and manufacturing processes.
This booklet will provide some insights regarding digital signal processing, on what the hardware and software are doing during acquisition process and also data post-processing. This booklet may provide some ideas also on what kind of small details that we may want to pay attention before making a decision to purchase a data acquisition system together with data post-processing software. Below are some details covered by this booklet.
Computer-aided engineering (CAE) has long proven its value as a troubleshooting and analysis tool, but is generally perceived as slow, delivering accurate results too late to drive development. The simulation process with traditional CAE tools is slow due to tedious geometry cleanup processes, and simulation disciplines are disconnected from each other, hampering efficient workflows.
In such industry that is facing tough market competition like automotive industry, having product durability issue during prototype testing and validation stage will be quite challenging, or sometime even quite frustrating. Especially when you are the testing engineer or project manager that has to ensure that all prototype testing and validation is done within the schedule.
The simulation and CAE in medical devices is very important as it can save millions of dollars for the industry, e.g. by reducing the number of required benchtop test, clinical trials, or by accelerating the regulatory approval process. The FDA and other regulatory agencies worldwide are supporting the collaboration effort in the simulation field driven by industry.
When we move to engine sound and vibration evaluation, we will have more methods and approaches that can be used to troubleshoot or improve the sound characteristics. In many cases, engine is considered as source of the vibration and sound. The fact that sound can be transferred through structure borne, air borne, or liquid borne makes acoustic/sound analysis becomes more challenging.
