    摘要: Various filter options in the current setpoint channel are available for optimal adjustment of a drive system to an elastomechanical system. The present method permits optimal adjustment of the speed controller through measurement of the speed control system by automatically determining possible parameters for a filter setting which may optionally be necessary. In a simulation calculation in the frequency range which relies on data from the measured system, a check is performed to determine whether the speed controller must be equipped with filters. In addition, the possible control parameters for the gain and the reset time of the speed controller are determined.

    摘要: A method for drilling or cutting a pin surrounded by solid material includes the use of a water jet tool having a nozzle that is arranged at an angle with respect to a main body of the water jet tool. The water jet is directed over a portion of the surface of the pin, and removes that portion thereby fragmenting the pin. In order to minimize damage to the surrounding material, the portions removed touches the interface between the pin and the surrounding solid material at a minimal number of points and over a minimal extent of the interface. The method is applicable in particular to the removal of pins used in a press-fit for the securing of blades on a turbine rotor. The method facilitates “in situ” removal of pins within a confined space in a short time and at reduced cost.

    摘要: An apparatus for inspection of a gap between two surfaces, at least one of which is ferromagnetic, for example in a generator, includes a sensor platform (26) for one or more sensors (26a) and an elongated mount (23), which can be moved out, for the sensor platform (26). The mount (23) can be moved in and out of the gap through an access opening, can be moved out over the length of the gap and can be rolled up outside the gap by a drive (24). In its moved-out state, the mount (23) has a curvature in a lateral cross section. In addition, the mount (23) has a plurality of magnets (27) by which the mount (23) is brought into contact with a ferromagnetic surface. The magnets (27) are attached to the side of the mount (23) facing away from the ferromagnetic surface, ensuring that the mount (23) slides along a ferromagnetic surface. The apparatus allows inspection of gaps from a height of 4 mm and is distinguished by a simple and physically small design.
