Today’s powertrain designs, like start-stop systems or downsized engines, often induce torsional-vibration phenomena, which negatively impact NVH (noise, vibration, harshness) performance and ...

A new advance in vibration monitoring, developed with EPRI, facilitates the measurement of torsional vibration and is expected to be of significant value to power plants relying on a wide range of ...

All rotating equipment power trains found in a power plant have some amount of vibration, usually caused by mechanical unbalance of the rotating system, shaft misalignment, or weakness in the bearing ...

This is a 3D model of a four-cylinder engine in MapleSim software from Maplesoft. The software lets designers use symbolic and numeric techniques to diagnose vibration issues on machines powered by ...

This paper was first presented at the Gas Machinery Research Council 2021 Gas Machinery Conference in Louisville, Kentucky in October 2021. Because of the original length of the paper, it has been ...

The last few years have shown progress in finite-element analysis intended for use by design engineers. Many programs that work with CAD provide several different types of analysis, and the range of ...

An integrated software suite for noise and vibration testing, LMS Test.Lab Revision 5 comprises modules for rotating machinery, structural and acoustic testing, environmental testing, vibration ...

This drum-shaped object has a metal clamp attached by metal rod to one flat side of drum. A mark reads: Torsional Vibration Damper. For general information about the UCLA differential analyzer, see ...

All of this uncertainty makes performing a torsional analysis of a train being driven by a VSI quite problematic. It is the author’s opinion that unless excitation information for the specific ...
