Development of a Robot-Based Test Bench for the Destructive Testing of Components

CODEN: JTEVAB

Abstract

This paper presents a novel approach for robot-based mechanical testing on the component level using a high degree of flexibility in the superimposition of loads, which allows their application to test various geometries and conditions. To validate our approach, tensile tests were performed using different control modes: position control, force control using a six-axis force/torque sensor, and path control using optical tracking of markers. The last two sensor-guided control modes are used to compensate unwanted force components that may occur in a system with six degrees of freedom. For reference, the same tests were performed on a conventional universal testing machine and were in good agreement. Subsequently, the flexibility of the robot-based test setup is demonstrated by two different component tests; a bicycle frame and a snowboard with high compliance were examined with different load cases. It was demonstrated that in path control mode an improvement in the accuracy of absolute positioning occurs and compensation for any transverse forces is possible. In addition, the path control mode enables the preservation of the initial load vector relative to the surface, even under significant deformation of the component.
