Precision Mechanics
Is the required stiffness met? Are the material stresses within limits? Is there no hidden stick-slip? Does the assembly meet its accuracy when all production tolerances are accounted for?
Drafting Specifications
A good design must fulfill many specifications, for example specifications concerning mass, stiffness, reproducibility, cost of goods, environmental conditions or heat dissipation. By drawing…
Concept Design
A good concept study gives you insight in the feasibility, cost of goods, design alternatives and the required development time. With the chosen concept you can timely adapt…
Qualification
Of course first time right is the goal of a new development. The preliminary phase of concept design, drafting specifications and conducting the required analysis will bring you close…

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...

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...
Worst-case Tolerance Stack-up Analysis
Suppose that you went through your tolerance analysis step plan and made a tolerance chain. The only thing to do now is to add up all tolerances. This seems easy enough but there are a few questions to consider: What to do with asymmetrical tolerances? Do you perform...
Tolerance Stack-up Analysis
Tolerances become important as soon as you design an assembly of parts. Of course each dimension must be provided with a tolerance. But in an assembly the tolerances become important because all parts must fit. In this article I tacitly will assume that we are dealing...
