Toolkit Mechanical Calculations


As a designer you regularly perform calculations and analyses for your design. Vink System Design & Analysis has put together an Engineering Toolkit for some of these calculations and analyses. This Engineering Toolkit consists of several software programs and an Excel spreadsheet.

These programs have been developed by Vink System Design & Analysis. You can download and use FlexBeam Lite, HertzWin and FlexHinge for free. Flexbeam Pro and TolStackUp are not free. The following programs are included in the Engineering Toolkit:

  • TolStackUp. A professional Excel spreadsheet (template) for tolerance analysis
  • FlexBeam Pro. A program to calculate beam deflection and buckling;
  • FlexBeam Lite. A less extensive version of FlexBeam Pro (free);
  • HertzWin. A versatile program to calculate Hertzian contacts (point or line contacts) (free);
  • FlexHinge. A program to calculate flexure hinges (free).

The software programs allow you to perform all necessary calculations quickly and accurately. The programs also come with an expandable material list and an extensive help function.
