Fatigue analysis – a visual topic for discussion

There is some excellent fatigue analysis system software available today. Go online, and you will find fatigue calculators that compute stress concentration, crack growth, safety factors, multiaxial states of stress and many other parameters. However, such software can be limited in the way the results are presented, and how you have to enter data. For example, if you “re-tweak” a mechanical design, you may have to resubmit data even if it hasn’t altered. Such programs often feel outdated, with results displayed graphically or as results tables, with nothing to visually link them to the CAD drawings they support. However, in recent years a new generation of fatigue analysis (FA) software has come on the market, which uses CAD visualization and even engineering animation tools, integrating with existing 3D modeling and CAD drafting software to display potential areas of failure directly your design. SolidWorks, ABACUS and Autodesk are just three of the major software companies offering integrated visualization services for engineering analysis. They include finite element analysis (FEA), computational fluid dynamics (CFD), thermal analysis and kinetic computation tools, as well as fatigue analysis software. The software is constantly being refined and updated, working seamlessly within the CAD drafting and 3D modelling environment. Tools like these have been a staple part of mechanical CAD in the aerospace and aviation industries for years. They are also at the forefront of automotive design. In consumer goods, they are used to analyze the design of everything from lawn mowers to radio controlled models. We at �ۿ۴�ý Technologies offer an extensive range of mechanical design and visualization services, including solutions for CFD and fatigue/thermal analysis.

The Importance of Data Cleaning

Data is only as useful if it’s accurate, and if it isn’t, unwary users can be lead astray. Bad decisions are often the result of bad data, or worse, no data at all. In mechanical engineering, clean and accurate data is an absolute necessity. Imagine if you didn’t know quite how strong a component really was because of an incomplete or gappy data set? That’s bad news.

Unfortunately, poor quality data is not at all uncommon. In all fields (even in mechanical engineering and other hard and supposedly precise sciences) people at all levels are much too inclined to take data at face value, without looking too hard at its provenance and level of precision.

If your data does prove to be scrappy and problematic when it is examined closely, all is not lost. Our data cleansing services can help transform a poor data set into something that is usable at the best possible accuracy. Holes may be reparable through interpolation or inference, and it may be possible to reduce noise levels or remove interfering signals.

The data output from older measuring equipment and system software programs can also be problematic in format. In these cases the numbers are accurate enough, but picking them out of obscure placements and positions may not be simple. In fact, the process of just getting old data into a readable format can be very time consuming without the right expertise. Get in touch today and see what we can do for your data.
