Tangential Load in HertzWin

With the program HertzWin you can calculate Hertz point and line contacts. The influence of a tangential load can also be calculated. HertzWin has been available online for free since March 2009. In older releases of HertzWin (prior to release 3.1.2) a general...

Advanced Method of Tolerance Analysis

In previous articles about tolerance analysis, I discussed the step-by-step plan and the way of adding up. The latter can be a worst-case sum or a statistical sum. In ‘The distribution of tolerances’ I also discussed the types of distributions that may...

The Distribution of Tolerances

In a previous article the statistical tolerance stack-up analysis is discussed. It is usually profitable to do a statistical tolerance stack-up analysis instead of a worst-case analysis. A worst-case analysis often leads to low tolerance specifications and therefore...

Statistical Tolerance Stack-up Analysis

In the article Worst-case Tolerance Stack-up Analysis you read about the worst-case or linear stack-up analysis. In such an analysis it is assumed that all dimensions in the tolerance chain have worst-case deviations form their nominal value. In a statistical analysis...
