โฆ Synopsis
A synchronous vibration eliminator applied to an object moving in a plane is investigated. The equation of motion of a system, which consists of a rigid object and several free rotating vibrators placed on this object, are introduced. Necessary conditions are found under which vibrators, moving synchronously with a force acting on an object, can eliminate object vibration. Computer simulation of an object and vibrators behaviour is done. Some time-runs of object vibrations and co-ordinates of vibrators positioning are shown. It was proven that in reality, elimination of vibration occurrence and vibrator movements stabilize in such a way that they move with constant velocities and phases. Simpli"ed solutions of equation describing object movements were found, and then vibrator forces that induced vibrator movements were de"ned. It was found on which parameters these forces depend and how they change in relation to vibrator positions. The zero points of these forces were obtained and these points are the vibrators equilibrium positions. It was proven that by ful"lling certain conditions such positions of vibrators give full reduction of an object's vibration.

In this paper, an analytical approach to the crack detection of rectangular plates under uniform external loades by vibration analysis is established. The damage is considered as an all-over part-through crack parallel to one edge of the plate. Avoiding non-linearity, it is assumed that the crack, a
