Experimental device for self-adaption structure teaching

Abstract

The invention discloses an experimental device for self-adaption structure teaching. The experimental device for self-adaption structure teaching comprises a frame, an outer frame body, an inner frame body, a rope and pulleys. A weight balancing iron block is arranged on the outer frame body, then, the counter weight of the inner frame body is changed, and therefore the outer frame body and the inner frame body can always achieve a balance in different positions. Due to the fact that the counter weight of the outer frame body has a certain value, if the friction force of the pulleys is not taken into consideration, the tensile force of the rope also has a certain value, namely, the system is kept balanced by changing the shape instead of force, and self-regulation and self-protection is achieved through the structural system. When the load increases, the shape of the structure can be greatly changed while the internal force is basically kept unchanged. According to the experimental device, students can visually know the features of the self-adaption structure by conducting loading to observe the change condition of the system along with the change of the load, the leaning interest of the students is motivated, and the students explore the principle. The experimental device is easy and convenient to install, and the manipulative ability of the students can be trained.

Description

technical field [0001] The invention belongs to the technical field of teaching instruments, in particular to an experimental device for self-adaptive structure teaching. Background technique [0002] Freshmen in colleges and universities are often full of curiosity about their majors at the beginning of their enrollment, but at this time they do not have the basis for direct study of professional courses. Introducing the basic principles through simple and ingenious experiments is to answer students' confusion and stimulate professional interest. an effective way. [0003] However, the existing professional experimental devices are often expensive, and must have certain professional skills to operate, which makes it unrealistic for all students in the lower grades to practice, and it is impossible to guarantee the teaching effect.
