Abstract

The invention belongs to the technical field of precise scientific instruments, and particularly relates to an online automatic detector for the mechanical parameters of the materials under the complex working conditions. The online automatic detector comprises a shell, and a precise indentation test unit, a base magnetic force moving unit, a material surface polishing unit and a guide rail driving unit which are arranged in the shell. The precision indentation testing unit and the material surface polishing unit are arranged on the guide rail driving unit and are in sliding fit with the guiderail driving unit, and the guide rail driving unit is fixed on the base magnetic moving unit. The online automatic detector for the mechanical parameters of the materials under the complex working conditions is simple in structure, can carry out the indentation test under service conditions, can accurately solve the mechanical parameters, such as material hardness, elastic modulus, yield strength, residual stress, fracture toughness, etc., and can solve the system errors caused by displacement and load detection units in complex environments.

Description

technical field [0001] The invention belongs to the technical field of precision scientific instruments, in particular to an online automatic detector of mechanical parameters of materials under complicated working conditions. Background technique [0002] Indentation technology is a technology that loads the surface of the material through the indenter, measures the indentation area, and obtains the load-displacement curve analysis to evaluate the material performance. This technology is based on elastic mechanics. The curve is measured through experiments, the elastic modulus can be calculated from the unloading curve, the hardness value can be calculated from the maximum loading load and the contact area, and creep, residual stress, fracture toughness and other parameters can also be calculated. The on-line automatic detector of mechanical parameters of materials under complex working conditions is mainly mechanically pressed into the surface of the test piece through the...
