This paper summarises the results of motion analysis of a platform mechanism with a monolith design. A four-link planar mechanism was engineered in which the platform positioning is effected via one passive link and two eccentric links actuated by stepper motors. The prototype of the device was fabricated following a computation procedure based on the classical mechanism and machine theory and FEM calculations. Testing performed on the model and on the real device revealed the presence of two points on the platform for which the resultant of two independent perpendicular displacements implemented by two stages can be obtained for small values of angular displacement.

Artykuł zawiera wyniki badań ruchu mechanizmu platformowego wykonanego w technologii monolitu. Zaprojektowano i wykonano czteroogniwowy mechanizm płaski, w którym platforma jest pozycjonowana przez jedno ogniwo bierne oraz przez dwa ogniwa mimośrodowe poruszane silnikami krokowymi. Po wstępnych obliczeniach klasycznego modelu tmm mechanizmu i następnie obliczeniach MES wykonano prototyp urządzenia. Badania modelowe i rzeczywistego obiektu wykazały, że na platformie znajdują się dwa punkty, w których można składać dla małych przemieszczeń kątowych dwa niezależne, prostopadłe przemieszenia pochodzące od napędów.
