| 20080229836 | Apparatus and Method For the Vibroacoustic Inspection of a Motor Vehicles - The invention is an apparatus and a method for carrying out a vibroacoustic inspection of a motor vehicle that features at least a front and a rear axle, with a test stand that is directly or indirectly connected to at least one of the two axles by means of a force flow and relative to which the motor vehicle is tied, wherein at least one vibration generator of a first type is provided along said force flow in order to generate vibrations below 50 Hz. The invention includes at least one second vibration generator of a second type, which provided along the at least one force flow or parallel to the force flow, for generating vibrations above 30 Hz, preferably above 100 Hz, and the at least one second vibration generator is operatively connected to the motor vehicle. | 09-25-2008 |
| 20090000385 | Excitation Test Method and Apparatus for Vehicle - A vehicle excitation testing system and method can include a device for simulating a vehicular motion and vehicular vibration and then measuring response. The system is designed to test front and/or rear wheel sections of a vehicle. The testing system can include a vehicle suspension system including a wheel and chassis, an excitation actuator connected to the suspension system, and a dummy or a real vehicle body linked to the suspension system and having a frame. The frame can be positively attached to the ground surface or floor or other similar isolated and stable base surface. Measuring devices can be connected to the frame, suspension and/or wheels. When the vehicle is excited to simulate road and other conditions, the wheels, suspension system and the vehicle body vibrate. Measurement of these transmitted vibrations can be studied in order to determine how to best control unwanted or unnecessary vibrations in the vehicle. | 01-01-2009 |
| 20130205905 | AUTOMOTIVE RATTLE DETECTION SYSTEM - A system for detecting rattles, squeaks and other annoying sounds in a vehicle can include a vibration generator and a clamping device configured to attach to the vehicle. | 08-15-2013 |

| 20100199774 | Vibrating Plate with Unbalanced Shafts Arranged at an Angle - A vibrating plate for compacting soil comprises an upper mass; a lower mass, which is elastically coupled to the upper mass and which has at least one soil contact plate, and; a vibration generator device that acts upon the soil contact plate. The vibration generator device comprises at least four unbalanced masses that can each be rotationally driven about a rotation axis, the rotation axis of at least two of the unbalanced masses being arranged at an angle to the rotation axes of the other unbalanced masses. One of the unbalanced masses depicts a reference unbalanced mass that does not require its own phase adjusting device. On the other hand, a separate phase adjusting device is assigned to each of the other unbalanced masses, enabling the phase position of these unbalanced masses to be individually adjusted with regard to the reference unbalanced mass. | 08-12-2010 |
| 20110016980 | MONITORING SYSTEM FOR SELF-SUPPLIED BEARING - The present invention describes a system for taking the necessary energy for operating the electronic circuit for monitoring a bearing (A) directly from the rotation movement, namely from the kinetic energy of the bearingi.e by energy harvesting or scarvenging. All information read on board the bearing (A) by the sensors ( | 01-27-2011 |
