METHOD AND DEVICE FOR DIAGNOSING ELECTRIC SWITCHES
The invention relates to a method for diagnosing switches and to a diagnostic device for switches in tracks of rail-bound traffic routes or other three-phase drives having a cyclic operating pattern. With the aid of at least two multidimensional magnetic field sensors, in each case the current of a suitable phase conductor of the drive is measured. The invention relates to two different measuring methods, which can be implemented by means of the same device. Depending on the type of measurement, in addition, by using one of the two sensors, the current of a further conductor is measured contactlessly at the same time as the phase conductor already mentioned. The measured values from the magnetic field sensors are transmitted via measuring cable or BUS or via radio by means of a suitable interface to a data processing system and are evaluated and stored there. The direction of rotation of the three-phase current applied to the drive is measured by the data-processing system from the time shift of the signals of two phases connected to the drive. During the evaluation, use is made of the fact that the current or power demand of the drive can be determined via the current intensity of any desired phase conductor and can thus be used as a measure of the sluggishness of the points. The condition of the points is determined by the current or power demand values for both directions of rotation of the drive being compared with reference or empirical values which are stored in the data processing system. From this comparison, a maintenance outlay to be expected for the points is determined by the data-processing system.

The invention relates to a method for optically measuring the contact wire thickness of a railway catenary, wherein the contact wire has a receptacle for a suspension clamp on both sides of the contact wire in the upper region of the contact wire and is semicircular in the lower region of the contact wire and has a wear region in the contact wire mirror, the manifestation of which wear region is measured. The problem to be solved by the invention is that of developing an optical measurement method that allows the wear of a contact wire to be determined exactly even if said wear is angled, wherein a contactless measurement method shall be used, which measurement method determines the contact wire thickness, the lateral position, and the height of the contact wire especially in train station and siding areas. This problem is solved according to the invention in that the current diameter (DRest) of the contact wire mirror (S) depends on the height (h) of an isosceles triangle related to the semicircular lower contact wire region and on the radius (r) of the contact wire, wherein DRest = r + 0.5 V4r2 - S2 applies in the case of straight wear and a viewing angle < 20°, and a table constructed in steps is created on the basis of this dependence, which table forms the basis for a measuring gauge related to each contact wire type, which measuring gauge allows an associated line length to be read off in the event of a reduction of the total diameter (D) of the contact wire (1), wherein the measuring gauge (4) has the contact wire mirror (S) as a linear reference value and a straight having a defined slope is created by connecting the ends of the lines, which straight is duplicated and mirrored, such that a triangular region is formed in the measuring gauge, which triangular region is digitally placed onto an enlarged measurement recording as a permissible measurement range, which measurement recording is produced by a camera (6) arranged vertically under the contact wire (1), which camera (6) is equipped with one or more lasers (10), such that the actual degree of wear of the contact wire mirror surface is determined and compared with a permissible value and evaluated.
The invention relates to a computer-implemented method for calculating a rail profile that is optimized with respect to reduce noise emission, and to a rail, the profile of which is selected such that compared to profiles of the state of the art, the noise emission is significantly reduced. The method models the rail profile of a standard vignoles rail of tracks for rail-bound vehicles, which serves as reference for the estimation of the vibration behavior. The parameters of the rail profile are then systematically changed, and the vibration behavior is calculated for each rail profile. Taking into account the wheel-rail interaction and the sensitivity of the human ear, the effect of the sound emission of the rails is evaluated for the adjusted parameters, and optimized. An acoustically optimized rail profile is disclosed, wherein the center of gravity of the rail head has a shorter distance to the center of gravity of the rail base than the standard profile of the vignoles rail.

INSULATED RAIL JOINT AND METHOD FOR CUTTING AN INSULATED RAIL JOINT
The invention relates to an insulated rail joint and to a method for cutting an insulated rail joint, wherein the insulated rail joint has rail ends adjoining one another which are electrically insulated from one another by an electrically insulating intermediate layer, and the insulated rail joint is designed as an inclined joint in the area of the rail head as far as the region of the center of the rail height and is designed as a butt joint in the rest of the rail web as far as and including the rail foot, and wherein the transition between inclined and butt joint is continuous.
The invention relates to a method for forming a rail track component by forging and to rail track components forged by means of said method. According to the invention, steel which consists of a basic bainitic structure is used for the rail track component. After the forging of the rail track component, the cooling is carried out in two stages. Forging is carried out within a time interval in which the structural formation of the steel is not substantially affected. The steel is then cooled down in a controlled manner to a temperature at which the conversion into the desired bainitic structure takes place completely. The temperature is then maintained until complete conversion over the entire cross section of the rail track component has taken place. Only then is the cooling down to room temperature continued. As a result of the method, the basic properties of the bainitic steel, such as hardness, tensile strength, elongation at fracture and yield point, are not disadvantageously changed. Rail track components produced by said method can be used, for example, as switch blades, switch frogs or transition rails. Said components are also distinguished by high hardness, e.g. between 420 and 480 HB, with at the same time high elongations at fracture of more than 9%, a high tensile strength of more than 1400 N/mm2 and yield points of greater than 1000 N/mm2.

The divided longitudinal sleepers are oriented relative to each other and installed in such a way that the joints of the longitudinal sleepers are aligned along a straight line, which thus can serve as a rotational axis for folding up a side of the switch. The joints aligned on the rotational axis act similarly to a hinge band so that complete switch segments, such as a switch end part or the core region, can be folded along said line.
