The Draft International Standard ISO/DIS 2631 "Guide for the Evaluation of Human Exposure to Whole-Body Vibration" provides an excellent base for setting acceptable levels of vibration on ships.2 A standard for evaluating vibration levels has been needed for some time and the new standard not only provides a sound foundation for evaluating vibration, but also permits the vibration levels to be rated numerically as percentages of the established standard of fatigue-decreased proficiency. The standard is related to frequency, direction of motion, and the time exposure at the different locations in the ship. "Safe exposure limits" and "reduced comfort limits" are defined in terms of percentages of this same fatigue-decreased proficiency level.

ZusammenfassungIn der öffentlichen Diskussion rücken Einflüsse der Bedienung von Fahrerinformationssystemen auf die Verkehrssicherheit mehr und mehr in den Fokus. Um diese Einflüsse zu überprüfen, sind allgemein anerkannte und standardisierte Methoden nötig, die auch früh im Entwicklungszyklus eingesetzt werden können. Der Lane Change Test ist eine normierte Fahraufgabe zur Ermittlung der Ablenkungswirkung von Zweitaufgaben im Fahrzeug. In einem Normenentwurf sind konkrete Maße zur Beurteilung der Ablenkungswirkung definiert. Im Artikel werden ergänzende Maße vorgeschlagen, die eine absolute Vergleichbarkeit verschiedener Systeme ermöglichen und eine Zertifizierungsgrundlage für sichere Fahrerinformationssysteme liefern können.

STEP-NC is a new CNC data interface proposed to replace ISO 6983, and has been partly formed into the draft international standard (ISO 14649). In this paper, the STEP-NC-based part program is analyzed, and the general methodology and tools for STEP-compliant application development are introduced. Then a framework for STEP-NC interpreter is proposed based on the SDAI method and the implementation solutions are presented. The EXPRESS compiler is used to convert the milling schema into C++ classes, and the information is extracted from the file in aid of data access tools. The said interpreter, which is fundamental to STEP-NC based machining, is also implemented with supporting tools in the ST-Developer environments. It is used to read the STEP-NC file into ROSE working form, and then extract and organize the manufacturing information in an object-oriented way.
