Partner in product development

With Vink System Design & Analysis I (Jaap Vink) offer engineering services to companies.  Specialized in precision mechanics, I am an experienced and result-oriented partner in the development of complex opto-mechanical and mechatronic systems where high accuracy is required.

To perform regular or special mechanical calculations and analyses, I have developed a toolkit of software programs and a spreadsheet. You can download and use it.

Engineering Toolkit

Engineering Toolkit Vink SD&A for Mechanical Calculations

Spreadsheet Tolerance analysis

TolStackUp is a tolerance analysis spreadsheet (template) created in Microsoft Excel. It is designed to analyze and manage the effects of dimensional deviations of parts in an assembly.

Calculate Beam Deflection Pro

FlexBeam Pro is an easy-to-use beam deflection and buckling calculator. After entering the data, FlexBeam Pro performs all necessary calculations.

Calculate Beam Deflection Lite

Do you want to try FlexBeam first or do you not need the more extended functionality of FlexBeam Pro? Then download the free FlexBeam Lite version.

Calculate Hertz Contacts

With HertzWin you can quickly calculate point and line contacts. This handy, free program automatically performs all Hertzian contact calculations.

Calculate Flexure Hinges

Use the free FlexHinge program to quickly calculate the stiffness and material stress of a flexure hinge. It performs all calculations automatically.

Download

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. You can download and use this toolkit.

Testimonials

I’m using FlexBeam to support my classes as a mechanical design teacher at a Technical School – Javier, Spain

I have downloaded your program and have confirmed that your Hertz Contact Stress calculation matches what I have been using. I believe that HertzWin will be helpful in quickly checking my hand calculations – Michael, USA (Pennsylvania)

I can only be positive about FlexBeam, very practical! – Philippe, Belgium

I have been a user of your FlexHinge software for the past few years and have found it very useful – Joey, USA

Tolerance Stack-up Analysis

Tolerances become important as soon as you design an assembly of parts. Of course, each dimension must be given a tolerance. But in an assembly, tolerances become important because all the parts must fit together. In this article, I will implicitly assume that we are...
