Problems solved by technology

[0002] At present, most engineering colleges and universities adopt the method of teaching theoretical courses and experimental courses separately for the teaching of "Material Mechanics" and "Mechanical Principles". There are problems in the connection of knowledge. At the same time, the concretization and visualization of the transmission mode of the typical transmission mechanism in the theory class of "Principles of Mechanics" is relatively abstract and difficult for some students, which will affect the teaching efficiency of teachers and students' understanding of basic knowledge. degree of mas

Abstract

The invention relates to a portable tensioning/twisting composite material mechanical property testing machine. A tension sensor and clamping heads are fixed to a tension seat group; the tension seat group is fixed to a guide rail sliding block and is matched with a clamping head group on the opposite side; a unidirectional tensioning function and a unidirectional twisting function are respectively realized by the combination of force transfer mechanisms, such as a gear, a worm wheel, a worm and a screw nut, and electric motors. The two electric motors are adopted for respectively controlling two types of movement; related data are acquired by using the tension sensor, the torque sensor and an electronic scale; all movement control, data analysis and curve drawing are controlled by computer programs. The portable tensioning/twisting composite material mechanical property testing machine can be arranged on a projector of a teacher for observing more clearly, meanwhile, is suitable for teaching physical demonstration activities of academic classrooms of various engineering courses, and is small in overall size, compact in appearance and high in practicability.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a portable tensile and torsion composite material mechanical property testing machine. It is mainly used in the theoretical classroom teaching of "Material Mechanics", "Mechanical Principles", "Engineering Materials" and other engineering courses. Background technique [0002] At present, most engineering colleges and universities adopt the method of teaching theoretical courses and experimental courses separately for the teaching of "Material Mechanics" and "Mechanical Principles". There are problems in the connection of knowledge. At the same time, the concretization and visualization of the transmission mode of the typical transmission mechanism in the theory class of "Principles of Mechanics" is relatively abstract and difficult for some students, which will affect the teaching efficiency of teachers and students' understanding of basic knowledge. degree of mastery. However, most...
