NVH (noise, vibration, and harshness) prediction is a critical process in the automotive industry to ensure customer satisfaction, safety, and compliance with regulatory requirements. Modal analysis is a popular technique used for NVH prediction, involving both testing and simulation. The goal of modal analysis is to measure the natural frequencies, damping ratios, and mode shapes of a structure, which can be used to identify the sources of noise and vibration and make improvements to the design. While modal analysis offers several benefits, such as cost savings and faster time to market, there are also some challenges associated with the technique, including complexity and cost. In this article, we will explore modal analysis for NVH prediction, its benefits, and its challenges.

Aircraft manufacturers are facing stricter regulations for aircraft emissions, including environmental noise, and increased pressure to improve cabin acoustic comfort. Vertical take-off and landing (VTOL) vehicles, currently being developed to enable urban air mobility (UAM), must also be optimized to minimize noise pollution in densely populated areas.

Their approach, however, was the same—using Simcenter STAR-CCM+ Multiphysics CFD software allowed the engineers to simulate 2000 variegator design variants in 17 days, and then optimize the design of the feeding chamber to guarantee that the final product would have the desired home-made, variegated appearance each time.

Thermal characterization is crucial for comprehending the behavior of complex electronics. It involves analyzing and measuring heat generation, dissipation, and management. This article provides a basic overview of thermal characterization, including structure and function of electronic components, and various techniques and tools used in the field. Get a better understanding of thermal characterization and its significance in ensuring the reliability and safety of electronic components.

The evolution of power, size, and temperature in electronics design has led to new challenges in system reliability and lifetime. In the past, overheating of critical components was the major cause of system breakdown, but today, other issues also arise. Cooling is a 3D effect, and accurate thermal characterization is necessary for optimal design. The development of thermal transient measurements has culminated in the Cauer-ladder network model and the Simcenter T3STER™ thermal transient analysis software system. Using structure functions, engineers can now identify the physical characteristics of layers and evaluate the thermal performance at the system level, from LED packages to laptops and laser printers.

Transformer noise is caused by a phenomenon called magnetostriction. In very simple terms this means that if a piece of magnetic sheet steel is magnetized it will extend itself. When the magnetization is taken away. It goes back to its original condition. A transformer is magnetically excited by an alternating voltage and current so that it becomes extended and contracted twice during a full cycle of magnetization.

Strength and fatigue analysis made easier in simulations. Templates for fatigue analysis and their strength-only counterparts are relatively recent additions to Simcenter 3D. As a result, many engineers are unaware of them or the benefits that they can bring.
