Efficient validation of novel machine elements for capital goods.

Novel machine elements often constitute the basis for innovative capital goods. While they are typically qualified in model experiments under predefined conditions, the real operating conditions in capital goods may differ considerably. In order to enable an agile development of innovative capital goods, an upgraded setup of the model experiments is proposed: Uncertainties in the installation conditions of the machine elements are represented by a new type of phase change actuators (PCA). The approach is demonstrated by a novel type of backlash-free high-load bearing. [ABSTRACT FROM AUTHOR]
