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 exist: a normal...
Background Information of the HertzWin Calculator for Hertzian Stresses
Occasionally, contact stresses play a role in a mechanical design. Herzian stress equations are needed to calculate indentation and to check if the yield stress isn't exceeded. Because programming is a hobby of mine, it seemed like a good idea to make a Hertzian...
Toolkit: Help function sometimes not visible and blurry fonts in Windows 10
Fix the issue with non-visible contents of the help function and fix the issue with blurry fonts under Windows 10.
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...
