摘要： The present invention discloses an electromagnetic multiaxial fatigue testing machine, which includes a test piece fixing platform and an electromagnet loading mechanism arranged on a frame, wherein the electromagnet loading mechanism includes a first loading device for bend loading, and a second loading device for axial and torsional loading. The first loading device includes a first permanent magnet and a first electromagnet with a direction of a magnetic force generated therebetween is orthogonal to an axial direction of a test piece; the second loading device includes a second permanent magnet and a second electromagnet mounted on a swinging pair with a direction of a magnetic force generated therebetween is parallel to the axial direction of the test piece. An electromagnet principle is adopted in the invention for loading, which does not cause mechanical frictions, and different loading modes can be selected according to the actual stress requirements to conduct a uniaxial or multiaxial fatigue test on the test piece, so that the testing efficiency is improved, and the testing noise and testing cost are reduced.

摘要： Provided is an electromagnetic multiaxial fatigue testing machine, comprising a test specimen fixing platform (1) and an electromagnetic loading mechanism on a machine frame (2). The electromagnetic loading mechanism comprises a first loading device for bend loading and a second loading device for axial and torsional loading. The first loading device comprises a first permanent magnet (15) and a first electromagnet (6) having a direction of the magnetic force therebetween axially orthogonal to a test specimen (39). The second loading device comprises a second permanent magnet (16) and a second electromagnet (7) mounted on a swing pair and having a direction of the magnetic force therebetween axially parallel to the test specimen (39). The present invention uses the electromagnetic principle for loading, and therefore no mechanical friction occurs. Furthermore, different loading modes can be selected according to the actual force requirement of the test specimen (39) to perform a uniaxial or multiaxial fatigue test on the specimen (39), thereby improving the test efficiency and reducing noise and cost of the test.
