Abstract

The invention provides a one-time multi-deformation measurement device for a material mechanics experiment. The one-time multi-deformation measurement device comprises a base, a tensile rod piece, a compressed rod piece, an eccentrically compressed rod piece, an eccentrically tensile rod piece, a force sensor and a worm wheel force increasing mechanism device, wherein resistance strain foils are respectively adhered to points to be measured on the eccentrically tensile rod piece, the tensile rod piece, the compressed rod piece and the eccentrically compressed rod piece. According to the one-time multi-deformation measurement device for the material mechanics experiment, the resistance strain foils are connected with a resistance strain gauge to measure strain under a load. The device can realize simultaneous measurement on multiple deformations such as tension, compression, eccentric compression, eccentric tension, elastic modulus and the like of a measured object at a time; the device is simple in structure and easy to operate.

Description

technical field [0001] The invention relates to the technical field of material mechanics, in particular to a device for once-measurement of multiple deformations in material mechanics experiments. Background technique [0002] At present, in material mechanics experiments, experiments such as stretching, compression, eccentric compression, eccentric stretching, bending, and Poisson's ratio elastic modulus need to be measured separately. Not only are there many and cumbersome experiments, but also the number of experimental devices increases accordingly. cost of the experiment. Contents of the invention [0003] The purpose of the present invention is to solve the problem of providing a material mechanics experiment multi-deformation primary measuring device capable of simultaneously measuring the tension, compression, eccentric compression, eccentric tension, elastic modulus and other deformation measurements of the measured object in the material mechanics experiment. ...
