Electro-magneto-thermo-mechanical dynamic and synchronous loading device based on wedge-shaped rotating body
Disclosed is an electro-magneto-thermo-mechanical dynamic and synchronous loading device based on a wedge-shaped rotating body. The device comprises a carrier, a wedge-shaped rotating body and a pulse power supply, wherein the wedge-shaped rotating body is positioned above the carrier, the pulse power supply is connected to the carrier and the wedge-shaped rotating body through conductors, a test object is fixed on the carrier, the top of the wedge-shaped rotating body is connected to the output end of a driving shaft through a transmission shaft, the driving shaft drives the wedge-shaped rotating body to rotate and can apply downward pressure, and the wedge-shaped rotating body can be pressed against the test object and rotate on the surface of the test object.
Bend test apparatus for a hydraulic hose
Bend test apparatus (100) for a hydraulic hose (200), the apparatus (100) comprising a main rack (10), at least one sliding rail (11) extending in a longitudinal direction (L) and a carriage (13) which is slidable on the sliding rail (11) in the longitudinal direction (L) and which can be displaced by an actuator (20), wherein the apparatus (100) further comprises a first fixture (1) that is rigidly attached to the main rack (10) to retain a first end (201) of the hydraulic hose (200) and a second fixture (2) that is rigidly attached to the carriage (13) to retain a second end (201) of the hydraulic hose (200), and wherein the apparatus (100) comprises a load cell (30) that is attached between the carriage (13) and the actuator (20) so as to detect a force (F) which is applied via the actuator (20) onto the carriage (13) and thereby onto the hydraulic hose (200) in the longitudinal direction (L).
Torque and combined load fixture and test method
A method and apparatus for testing a specimen with pressure, applying a torque using one or more plates coupled to the test specimen, applying a bending moment, and/or applying an axial load, either separately or simultaneously, with or without rotating the specimen, and without the applied forces interfering with each other.
OFF-AXIS LOADING FIXTURE FOR TESTING SPINE BIOMECHANICS
A multi-axial spine testing system includes a physiological motion unit (PMU); a uni-axial test frame having an input; and a fixture configured to be attached to the test frame and facilitates a plurality of primary motions of one or more of the PMU and the fixture. The plurality of primary motions includes a linear motion of the input and a rotational movement of an output. The fixture has an upper assembly directly or indirectly coupled to the input. The upper assembly transfers the linear motion (T.sub.z) of the actuator to the rotational movement (R.sub.x) of the output. The upper assembly and lower assembly apply a bending moment (M.sub.X) and an axial compression (F.sub.z) to the PMU. An external transducer collects data related to or generated by at least the plurality of primary motions. The fixture simultaneously provides the bending motion and axial compression to the PMU.
Specimen test method
Disclosed is a test rig and a method for mechanical load testing of a specimen extending along a longitudinal axis from a first specimen end to a second specimen end and comprising a composite material extending along the longitudinal axis from a first composite end to a second composite end and a primary elongate component extending along the longitudinal axis from a first primary component end to a second primary component end, the first primary component end being the first specimen end, and wherein the composite material encapsulates the primary elongate component along a first interface region extending along the longitudinal axis from the second primary component end to the first composite end. The method comprises applying a load to the specimen resulting in an axial load component and a bending moment being imposed to the specimen.
Torque and combined load fixture and test method
A method and apparatus for testing a specimen with pressure, applying a torque using one or more plates coupled to the test specimen, applying a bending moment, and/or applying an axial load, either separately or simultaneously, with or without rotating the specimen, and without the applied forces interfering with each other.
