Abstract
A vibration excitator including a main body, a stinger which is adapted to move relative to the main body, in a particular working direction, an actuator coupled to the main body and the stinger, wherein the stinger has a first end that is coupled to the main body, and an opposite second end that is intended for attachment to an object to be examined, wherein the stinger has an elastic centre point, wherein the main body has a centre of gravity, and wherein L1=L3 applies, wherein L1 is the distance between the elastic centre point and the second stinger end, measured along the said working direction, and wherein L3 is the distance between the centre of gravity and the second stinger end, measured along the said working direction.
Claims5
Detachable end piece for a stinger, which end piece has a head end face intended for attachment to an object to be examined, as well as a recessed sensor accommodation chamber arranged in the head end face, which chamber is completely situated in the end piece;
- wherein a sensor is arranged in the accommodation chamber;
- wherein the end piece is provided with elastic means which are adapted to couple the sensor to the accommodation chamber, and wherein the sensor is otherwise free from contact with the walls and the bottom of the accommodation chamber;
- and wherein the end piece, at its end situated opposite the head end face, is provided with coupling means or detachable coupling to a stinger.
Detachable end piece for a stinger, which end piece has a head end face intended for attachment to an object to be examined, as well as a recessed sensor accommodation chamber arranged in the head end face, wherein the end piece has a ring-shaped appearance;
- and wherein the end piece, at its end situated opposite the head end face, is provided with coupling means for detachable coupling to a stinger.
Force transmittal member, comprising a force-transmitting body having a head end face intended for mounting on an object to be examined, and an opposite end face intended for receiving a force;
- wherein a sensor accommodation chamber is recessed in the head end face;
- wherein a vibration sensor is arranged in the accommodation chamber;
- wherein the force transmittal member is provided with elastic means which are adapted to couple the sensor to the accommodation chamber;
- and wherein the sensor is otherwise free from contact with the walls and the bottom of the accommodation chamber.
