Machine Structure

Die axiale Steifigkeit von Kugelgewindetrieben ist wesentlich für das Betriebsverhalten von Werkzeugmaschinen. Während der Bearbeitung werden die Prozesskräfte über den Kugelgewindetrieb in die Maschinenstruktur übertragen. Kugelgewindetriebe tragen daher maßgeblich zur Qualität und Produktivität von Werkzeugmaschinen bei. Dieser Beitrag beschreibt eine Methode zur messtechnischen, prüfstandsgebundenen Ermittlung des Last-Verlagerungsverhaltens an Kugelgewindetrieben.   The axial elastic displacement of ball screws are essential for the operating behavior of machine tools. During machining, process forces must be transmitted to the machine structure via the ball screw. Ball screws contribute significantly to the quality and productivity of machine tools. This technical paper describes a methodology for the metrological determination of the load-displacement behavior on ball screws.

The load-displacement behavior of spinal motion segments is commonly determined from in-vitro experiments on cadaveric spines. However, clinically, it is often desirable to quantify the patient specific biomechanical properties of the spine in-vivo. Load-displacement measurement requires direct access to the appropriate anatomy, which is typically available in spinal surgeries that aim to correct lumbar spinal instability or scoliosis. We propose an approach to measure the spinal load-displacement behavior for use during these surgeries.
