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.
