摘要： The invention relates to a device for measuring and/or registering mechanical forces (F) with the aid of a measuring body (1) which can be influenced by the force to be measured. The measuring body is configured with a web (11) in which transverse forces and/or shear stresses occurrent in the web and dependent on the value of the force, can be evaluated with the aid of a magnetizing winding (3) and a sensing winding (4). The web (11) has a limited extension in relation to the measuring body (1) and has a limited thickness (t) such that evaluation of occurrent forces and/or stresses in accordance with magnetoelastic principles will take place substantially in or in the immediate vicinity of a neutral plane (23) located on the measuring body. The invention also relates to a method for the manufacture of such a measuring body.

摘要： In a process for measuring mechanical stresses in elements composed of magnetizable materials, a section of the element (10) is first magnetized in a predetermined direction, then an electric signal is generated while stresses are being applied by the magnetic field built-up by remanent magnetic polarisation (J) or by its changes in the vicinity of the element (10), after the magnetic field has dissipated. A measurement sensor for implementing this process is designed in such a way that the magnetizable element (10) contains a magnetized section in a predetermined direction, and that a magnet transducer (6, 22) arranged next to the section is coupled to the static magnetic field generated by mechanical stresses (S) or to the dynamic magnetic field generated by stress changes.

摘要： Method for measuring mechanical stresses and fatigue conditions in steel (1), whereby a pulse shaped electric current is applied to the steel through a pair of contact points (2-3-4), characterized in that the potential drop curves A(t) thereby generated between another pair of contact points (6, 7) are measured by repeated sampling (8, 9, 10). The steel subjected to the measurements can both be magnetized (11, 12) and demagnetized (2, 3, 5) by means of arrangements known per se and being employed for magnetizing the steel to selected points at the initial, the anhysteretic and the hysteresis magnetization curves. Comparison of the potential drop curves (10) at different magnetization makes it possible to determine the mechanical stress and the fatigue condition in the steel.

摘要： An instrument (17) for determining one or more stress characteristics within a surface layer of magnetisable material. Instrument (17) includes probe (7) having a carrier (8) rotatable about a rotation axis (Y) extending perpendicularly outwardly from a magnetisable material surface (M). An electromagnet (1) is mounted on t he carrier (8) and provides a pair of poles (3) spaced apart, one on either side of the rotation axis, on a pole axis (X) so that on carrier rotation the poles (3) circulate about the rotation axis (Y). The electromagnet (1) is energisable to produce a magnetic field (H) between the poles (3). A search coil (5) is fixed relative to the electromagnet (1) between the poles (3), on an axis (x) so as to lie in the magnetic field (H). Drive means (12) is operable to rotate the carrier (8) to selected angular positions. The probe (7) is positioned with the poles (3) adjacent the material surface (M) so that the magnetic field (H) extends into the surface, shifts in the magnetic field (H) caused by stress in the material surface (M) inducing representative voltages in the search coil (5) at the angular positions. Instrument (17) also includes control apparatus (18) for controlling operation of the drive means (12) and, at each selected angular position of the carrier (8) for receiving parameters from the probe (7) for determining the stress characteristics.

摘要： A method is described for measuring a change in the mechanical state aiming at detecting the disturbance the change in state has on a magnetic flux (o). This flux is brought to flow through at least a part of the body (1) under the influence of a driving magnetizing force (H0). In order to achieve an unambiguous measuring result the average length ((Alpha)) of the magnetic circuit is kept constant and independent of the change in the mechanical state. The flux (o) consists partly of a main flux (o0) having a definite direction and being of such a magnitude that the magnetic properties of the body depart from the region of irreversibility and partly of an alternating, gradually vanishing flux (oy) superimposed upon the main flux. The alternating flux must have such an initial magnitude that saturation is obtained in both directions of the alternating flux (ov). After the vanishing of the alternating flux (ov the disturbance generated through the change in the mechanical state is indicated or registered as a voltage which is induced by the change in flux corresponding to the disturbance. A device which works as explained above comprises means for generating the flux (o) through the body (1) which is arranged to form a magnetic circuit with at least a part of the body (1). This circuit should be essentially free from air gaps and have an average length ((Alpha)) for the driving magnetic force (H0) which is independent of the change in the mechanical state. The device is arranged to force partly the main flux (o0) and partly the superimposed alternating flux (ov) through the magnetic circuit. By means of a coil system (5) connected to a measuring or indicating device (8) the change in flux corresponding to the disturbance caused by the change in state is detected.

摘要： A rail axial force measuring method which removes the influence by a residual stress existing in a rail and measures an axial force borne by the rail quickly and accurately and a rail whose axial force can be measured. The rail axial force measuring method provided comprises the steps of imparting a stress sensing portion to the rail, exciting the stress sensing portion with an excitation head, detecting a change in magnetization of the stress sensing portion as a voltage signal with a detecting head, and measuring a rail axial force from the voltage signal. The voltage signal is a Barkhausen noise signal, and furthermore a configuration is also adopted in which the stress sensing portion locally heats up the rail to a gamma phase area, and thereafter it is heat treated at a temperature lower than that of the gamma phase area so that cementite is separated out. Furthermore, the present invention provides a rail having the stress sensing portion and whose axial force can be measured.
