In order to test the shock resistance of all kinds of devices such as emergency power systems, pumps, electrical distribution boards, etc., two heavy platforms are positioned upwards on an inclined rail system. The upper platform then crashes into the lower one in a controlled manner, triggering a horizontal shock. As a similar system has already been realised on site with Beckhoff and because the recording of the measurement data has to run very quickly, we used TwinCAT 3 from Beckhoff for the first time. Further projects with this system are sure to follow.
