    摘要： An oscillating device according to an embodiment of the present invention includes a vibrating table, an X-axis oscillating unit configured to oscillate the vibrating table in an X-axis direction, and a Y-axis linear guideway configured to couple the vibrating table and the X-axis oscillating unit slidably in a Y-axis direction perpendicular to the X-axis direction. The Y-axis linear guideway includes an X-axis rail extending in the Y-axis direction and a Y-axis carriage configured to engage with the Y-axis rail slidably in the Y-axis direction. A plurality of load paths of equal to or more than five streaks are formed between the Y-axis carriage and the Y-axis rail, each of the load paths being configured such that a plurality of rolling bodies roll therealong.

    摘要： A rigid body characteristic identification system which identifies rigid body characteristics of a measurement target including its mass and center of gravity position, provided with an immovable stationary part 10, moving parts 20 which can move with respect to the stationary part and include a measurement target T, support means 30 for supporting the moving parts with respect to the stationary part in a freely vibratable manner, measuring means 40 for measuring data which is necessary for calculating the natural frequency of the moving parts when the moving parts are vibrating, and analyzing means 50 for receiving as input the support conditions by the supporting means and the measurement data which was measured by the measuring means and for performing processing based on these support conditions and natural frequency calculated from the measurement data. The analyzing means uses the support conditions by the supporting means and natural frequencies which are calculated from the measurement data as the basis to identify the rigid body characteristics of the measurement target. Due to this, a rigid body characteristic identification system or rigid body characteristic identification method which can reduce the number of measurement points while identifying the rigid body characteristics with a high precision is provided.

    摘要： A system and method for producing and controlling a random signal with simultaneous control of both the power spectral density (PSD) and kurtosis (100) where a controlled signal is measured from a transducer, and converted to a PSD (111) using a Fast Fourier Transform (FFT). The measured PSD is compared (117) with a reference PSD (121) where an adaptive filter (119) is updated to compensate for the error. Simultaneously the kurtosis of the measured data is computed (125) and compared to a reference kurtosis (123). A feedback control loop (127) is employed to adjust the kurtosis of a white noise random generator with variable kurtosis (101). This white noise is then filtered by the adaptive filter (119) to provide the output signal used to drive the control process.

    摘要： Ein Simulations-Prüfstand für Kraftfahrzeug-Bauteile (12) weist eine Bauteilhalterung (10) zur Aufnahme des Bauteils (12) auf. Mit der sauteilhalterung (10) und/ oder dem Bauteil (12) sind Bewegungselemente (16) verbunden, durch die das Bauteil (12) zur Simulation vorgegebener Fahrsituationen bewegt werden kann. Ferner ist eine Steuereinrichtung (18) vorgesehen, die über Leitungen (20) mit den Bewegungselementen verbunden ist und diese steuert. Mit Hilfe einer Bewegungserfassungseinrichtung (24), wie einer Stereokamera, wird die aktuelle Bewegung des Bauteils (12) erfasst. Die erfassten Bewegungsdaten werden an eine Synchronisationseinreichung (28) übermittelt, wobei mit Hilfe der Anspassungseinrichtung ein Vergleich der aktuellen Bewegungsdaten mit den Fahrsimulationsdaten erfolgt und die von der Steuereinrichtung (18) ausgegebenen Steuerbefehle entsprechend angepasst werden.
