In order to evaluate the human's dynamic physical strain during work, for example during assembly work, an evaluation library of all executions carried out by humans is needed. Therefore, necessary measurements of muscular strains via electromyography have to be carried out which require standardized and repeatable external stresses,warranted by a test stand. Both the methods and the single development steps of the planning and dimensioning process of such a test stand are explained. After the general construction methodology, requirements to the test stand were made concerning the functional structure and the active principle of every single test stand components. Calculations and dimension by means of CAD programs as well as results from early tests and both spatial and financial determining factors were integrated into the modularly planned and assembled test stand, which can be used for many different movements of the human body. In addition to the realized solution approach, alternative solutions are presented.
