Abstract
Beschrieben wird eine Vorrichtung sowie ein Verfahren zur Simulation haptisch wahrnehmbarer Vibrationen eines Objektes (1), mit einer Objekthalterung (7), in die das Objekt (1) fixierbar und ueber einen Kraft-Momenten-Sensor (6) mittel- oder unmittelbar mit einer Aktuatoreinheit (3) verbunden ist, einem Vibrationsaktuator (5), der zumindest mit der Objekthalterung (7) in Wirkverbindung steht, sowie mit einer Auswerte- und Ansteuereinheit (8), die sowohl die Aktuatoreinheit (3) als auch den Vibrationsaktuator (5) unter Zugrundelegung von zumindest von dem Kraft-Momenten-Sensor (6) erzeugten Messsignalen ansteuert.

 

DE1004049938 A UPAB: 20060523 NOVELTY - The device has an object holder connected with an actuator unit (3) by a force-moment-sensor. A vibration actuator actuated by electric motors generates oscillation forms or vibrations with different frequencies, amplitudes and waveforms, that are transferred to an object, which is fixed in the holder, by the holder. An evaluation and control unit (8) controls the unit (3) and actuator based on measuring signals produced by the sensor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for simulating a haptic perceptible vibration of an object. USE - Used for simulating a haptic perceptible vibration of an object e.g. manually operated, motor propelled small device such as percussion drilling machine, grinding device and motor saw. ADVANTAGE - The device allows the user to simulate the haptic perceptible vibration of the object in the realistic manner and to perform the testing and estimation of virtually representable prototypes without the developing technological and cost intensive expenditure of an actual realization of the prototypes of the small devices. The device thus accelerates the development process of the small devices and reduces the cost of developing the small devices. The device helps the developers and designer of the small device to optimize the ergonomic construction of the small device housing under the aspect of the vibro-tactile characteristics.
