The present invention relates to an apparatus and a method for determining a scaling factor for a strain measurement in a machine element, comprising steps for measuring a strain in a measurement surface portion by means of a strain measuring device; for measuring a displacement of a detection surface portion of the machine element by an optical scanning; for determining a displacement field on a surface of the machine element on the basis of a model of the machine element and the measured displacement of the at least one detection surface portion; for determining a strain field on the surface of the machine element on the basis of the determined displacement field and the model of the machine element; and for determining a scaling factor of the strain measuring device on the basis of the determined strain field and the measured strain in the measurement surface portion.

Method and apparatus for determining upvalue factors for expansion measurements on machine elements

A device for additive manufacturing of components by selective irradiation of a powder bed, having a processing chamber&#x2014;in which at least one powder bed chamber and at least one radiation source are arranged such that the radiation source can irradiate a powder in the powder bed chamber, and wherein the device includes at least one induction coil, so that a component which is produced by irradiation of the powder bed can be at least partially inductively heated, and wherein the induction coil is movable relative to one or more powder bed chambers. A method for additive manufacturing of components by selective irradiation of a powder bed, in which method the component being manufactured is inductively heated at the same time, wherein the position of one or more induction coils for inductive heating is determined and adjusted based on the geometry of the component to be produced.

A method for vibration damping of at least one blade of a turbomachine, wherein initially at least one damping element is arranged on the blade such that it can move in the axial direction, employs a damping element having a larger permeability constant than the blade (&#x3bc;&#x3e;&#x3bc;), and then a magnetic field acting in the radial direction is generated at least temporarily during rotation of a rotor hub of the turbomachine in order to adjust the mass of the damping element in real time. A damping device includes, for example, a ferromagnetic damping element as well as a magnetic field source, and a turbomachine.
