Abstract

The invention discloses a portable type multifunctional material mechanics teaching aid which comprises a machine frame. The top face of the machine frame is connected with a first supporting plate. A second supporting plate is arranged below the first supporting plate. A driving device is arranged below the second supporting plate. A transmission device is arranged between the first supporting plate and the second supporting plate. The driving device is connected with the transmission device. A clamping device comprises a supporting head placed above the first supporting plate. A supporting stand column, an upper clamp base connected with the supporting head, a lower clamp base which penetrates through the first supporting plate and is connected with the output end of the transmission device and a set of clamp which is in detachable connection with the upper clamp base and the lower clamp base are arranged between the supporting head and the first supporting plate. A clutch device is arranged on the second supporting plate and controls the lower clamp base to rotate. Through axial displacement and rotation of the lower clamp base, various experiments such as stretching, compressing, bending and reversing and a deflection demonstrative experiment can be completed with various clamps matched, corresponding mechanical performance indexes of experiment pieces of different materials are obtained, operation is easy, and convenience and flexibility are achieved.

Description

technical field [0001] The invention relates to a classroom teaching aid of material mechanics, in particular to a portable multifunctional material mechanics teaching aid integrating miniaturization and multiple functions. Background technique [0002] There are usually five kinds of experiments involved in the teaching of material mechanics: tension experiment, compression experiment, torsion experiment, bending experiment and deflection demonstration experiment. At present, for tensile and compression experiments, electronic universal testing machines are often used in the material mechanics laboratory to complete these two experiments; for torsion experiments, torsion testing machines are used to complete the experiments; for bending experiments, bending testing machines are used to complete the experiments , there is no related demonstration experiment platform for the deflection demonstration experiment. However, these existing mechanical experiment machines are bulky...
