Don’t be Left in the Dark!

Don’t be left behind in the dark. Not knowing the importance of all the parts used in a tolerance stack-up can lead to lost time and make it more difficult for engineers to come up with the best solutions for design problems. 

Sensitivity or contribution analysis is a vital tool in the world of engineering. This mathematical technique determines how different values of an independent variable will impact a particular dependent variable under a given set of assumptions. It’s basically like having a pair of superpowered smart glasses that help you to see and understand stuff that hasn’t happened yet, so you can understand the order of importance of the parts in your stack.

Without it, you’re left in the dark.

In engineering, sensitivity analysis helps engineers understand how variables affect each other so they can identify an optimal design solution. It also provides a way to address the outcome of a design if the results turn out differently than what was expected.

While smart glasses seem to get better every year, they probably won’t help you with sensitivity analysis yet. Luckily, T360 can do what smart glasses can’t. Within T360, contribution analysis is automatically calculated to determine which dimensions have the greatest influence on a stack calculation. Because there can be so many different contributors to a stack calculation, having instant visual access to sensitivity allows engineers to quickly make decisions about which parts or components affect the overall tolerance stack and how they interact with each other.

Once engineers have this information they can perform “What-If” scenario analysis to quickly see how changes to these contributing parts will affect the overall tolerance stack calculations. In short, sensitivity analysis answers the question of which tolerance stack dimensions matter the most and which ones don’t.

After running, the result graphically shows the different levels of impact all the dimensions have against the others in the stack. The lower and upper represent the minimum (lower) and maximum (upper) values of the current analysis method of the current stack that deviates from the nominal.

You don’t need smart glasses to work smarter. When Tolerance360 does the heavy lifting in, engineers are freed up to spend their creative and analytical energies creating a better product, without being slowed down by tedious manual contribution analysis. T360 gives engineers the upper hand in performing, quick, comprehensive testing and analysis.
