Modular structure mechanical experiment platform system

Abstract

The invention discloses a modular structure mechanical experiment platform system, which comprises an experiment operation platform, an experiment structure system, a loading device and a measuring device. The experiment structure system comprises standard rod pieces, connecting joints and support parts; the standard rod pieces are basic modules for constituting an experiment structure; the connecting joints are used for being connected with the standard rod pieces to achieve hinged connection or rigid connection between the standard rod pieces; the support parts and the experiment structure are connected through the connecting joints, and the experiment structure is fixed to the experiment operation platform and provided with boundary constraints; the loading device is used for applying loads on the experiment structure and meets the loading condition in current theory teaching; and the measuring device is used for measuring the load, deformation and the internal force mechanical index of the experiment structure. The modular structure mechanical experiment platform system in civil engineering specialty teaching has the advantages of safe operation, high accuracy degree, high designability, comprehensive function, high teaching efficiency and the like, and autonomous teaching of the course experiment part of 'structural mechanics' is achieved.

Description

technical field [0001] The invention relates to the field of teaching and scientific research experiment devices for civil engineering specialty, in particular to a modular structure mechanics experiment platform system. Background technique [0002] "Structural Mechanics", as the core course of civil engineering major, plays a connecting role in the entire professional knowledge system. This course uses advanced mathematics as the basic calculation method, and conducts in-depth research on common idealized structural models on the basis of theoretical mechanics and material mechanics courses, and provides professional courses such as reinforced concrete structure, steel structure, foundation engineering, underground space structure, etc. provide an important theoretical basis. After years of development, the knowledge of structural mechanics has formed a complete theoretical system. [0003] Over the years, the concept of engineering education has advocated a teaching mod...

After searching, the Chinese invention patent (notification number CN 104751704 A) proposed a combined multifunctional structural mechanics experiment bench for the planar bar system structure. The test object adopts a combined and assembled design, but its structural support layout is quite limited. (It can only be arranged on the vertical frame of the bench), and only a single vertical concentrated force can be applied, the diversity of its experimental objects and functions is restricted
