Abstract

The invention discloses a mechanical testing system for a material with composite load in an induction heating mode. The mechanical testing system comprises a stretching module driving unit, a double-end torsion module driving unit, a testing system, an induction heating system and a visual system, wherein the stretching module driving unit drives synchronous stretching of a double-end torsion module bearing table along a horizontal direction of testing stand via a bidirectional ball screw; a double-end torsion module implements a double-end torsion loading conditions on a to-be-tested workpiece; the induction heating system comprises a motion part and an induction heating part and used for simulating testing of the to-be-tested workpiece under a high temperature condition; and the visual system comprises an industrial endoscope and an industrial camera, wherein the industrial endoscope can withstand certain high temperature conditions and used for acquiring and observing dynamic strain process of the to-be-tested workpiece under a thermo-mechanical coupling condition. The mechanical testing system provided by the invention can test the to-be-tested workpiece under the conditions of single load like stretching, torsion and fatigue and composite load, and employs the high-temperature endoscope and the industrial camera for testing of the dynamic strain process of the to-be-tested workpiece.

Description

technical field [0001] The invention belongs to the technical field of material mechanics test, in particular to a composite load material mechanics test system under induction heating mode. Background technique [0002] The mechanical performance test of materials needs to simulate the mechanical properties of materials under actual working conditions.
