Step-by-Step Example of Tolerance Analysis

A previous article described the entire step-by-step plan for building a tolerance chain. It was described using a relatively simple example. In practice, however, designs can be much more complex. And then the tolerance analysis of such a design is much more...

Stresses, Tribology and Contact Mechanics

When two objects come into contact, depending on the shape of the surfaces, there may be point or line contact. The contact force causes deformation and thus stresses in the material. If these material stresses are high, the material may fail. The material stresses in...

Setting up the tolerance chain step-by-step

The article ‘Step Plan Tolerance Analysis’, briefly summarizes the steps to achieving a good tolerance analysis. The following articles discuss the method of adding tolerances. Much attention has been paid to the Statistics of Dimensional Variations of...

Tolerance Stack-Up Analysis and Process Capability Index Cpk

Previous articles have discussed the use of statistics in tolerance analysis: how statistical summation works, how to account for the influence of different distributions, and how to combine worst-case with statistical contributions. The resulting picture is that the...

Rolling Contact Fatigue

Up to and including HertzWin 3.2.0, all calculated results are for a static situation. The most important material stresses for a static situation are the maximum shear stress and the von Mises equivalent stress. The Von Mises equivalent stress is most often used to...

Tangential Force Acting on a Hertzian Contact in HertzWin

With the program HertzWin you can calculate Hertz point and line contacts. The influence of a tangential force can also be calculated. HertzWin is available online for free since March 2009. No approximation but the exact solution In older releases of HertzWin (before...
