Electric Motors: Static/Offline Testing

Friday, February 24, 2012

Electric motors are a key component for running machines in most industrial environments. Therefore it is important that they are properly monitored to avoid unwanted failures or shutdowns. Read More

Ways to Reduce Boat Vibration and Noise

Wednesday, February 15, 2012

Some boats vibrate more and make a lot of noise. Vibration and noise in boat require immediate attention. Vibration and noise are related; vibration generates unwanted noise. Below are some ways to decrease vibration and noise on your boat: Read More

Signal Processing: Aliasing

Thursday, February 09, 2012

Aliasing is a phenomenon that can occur due to improper sampling or data collection, where the original signal is indistinguishable when reconstructing data from the collected samples. This usually occurs because the sampling rate and/or resolution is inadequate. Read More

Statistical Analysis: Random Vibration

Monday, January 30, 2012

There are two vibration situations in which statistical analysis is useful. The first situation occurs when the vibration amplitude of a system appears to be random in time. In this case, it is convenient to describe the response of the system statistically. This form of analysis is called random vibration analysis which is our main focus in this article. The second situation occurs when a system is complex enough that its resonant modes appear to be distributed randomly in frequency domain. This form of analysis is called statistical energy analysis.  Read More

Product Design: Performance vs Constraints

Friday, January 27, 2012

Every product starts out on the drawing-board with a set of objectives that define what the product must accomplish. Before clearly setting objectives for the design, it is critical to understand the constraints that may prevent it from achieving all the intended goals. Constraints inherently mean that there are limitations that have to be overcome; this may in the form of cost, ease of manufacturing, spatial restrictions, regulatory guidelines, etc. Trade-offs and compromise are expected during the evolution of a design from a concept to a fully functioning product. Read More
