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.

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.
Karma Automotive established a strategic partnership with Simcenter Engineering and Consulting services to meet NVH performance targets and implement state-of-the-art NVH testing and simulation processes. Simcenter™ software uniquely combines system simulation, 3D CAE and test to help you predict performance across all critical attributes earlier and throughout the entire product lifecycle.
John Wilson, technical marketing engineer at Mentor, a Siemens Business, explains how junction temperatures have a direct correlation to product reliability and performance. Using tools such as Simcenter™ T3STER™ and Simcenter™ Flotherm™ enable users to tackle the challenge of designing for reliability without the need for prototyping.
Simcenter Flotherm - The goal of electronics thermal design is to accurately predict component junction temperatures to ensure that they are within specification. CFD allowed designers to predict the flow of cooling air, and include 3D thermal simulations of the board and components, increasing the need for more accurate component level modeling.
Revolutionizing productivity, Electra Meccanica moved quickly, transforming a napkin sketch into a digital NX™ software design in a matter of days, then using Simcenter™ software to optimize and validate the performance of the all-electric SOLO. Finally, using NX CAM and 3D printing, Electra Meccanica built its dream car.
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.
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.
