Abstract

An oscillation decoupling device is disclosed with a load-receiving element which is mounted in an oscillating manner relative to a support unit at least along an active direction along which at least part of the load is applied having at least one sensor unit which detects an oscillation of the element due to the load and at least one actuator unit acting against the oscillation of the element. The support unit is modularly configured and serves as a support structure for at least one unit that receives the element and is elastically deformable in the active direction of the load. The load-receiving element is connected to the elastically deformable unit. The at least one actuator influences the deformation applied to the at least one unit, or is integrated thereon, so that the at least one actuator initiates a deformation acting against an elastic deformation due to the load inside the unit.
