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...

Problems solved by technology

However, the currently applied experimental platforms usually have shortcomings such as single structural objects, limited experimental functions, and poor operability.

[0004] After searching, the Chinese invention patent (notification number CN 102394020 B) proposed a universal experimental bench for mechanical properties of building block plane structure. Experimental analysis of unequal span structures

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

After retrieval, the Chinese invention patent (notification number CN104332086 B) proposed a structural mechanics experimental platform, which can realize the experimental research on the three-dimensional bar system structure in space, but does not involve the modular design and assembly of the experimental structure

After searching, the Chinese invention patent (notification number CN 104568601 B) also proposed a space structure mechanics experimental device for the space bar system structure. The experimental structure can realize modular assembly, but the structural bars can only be rigidly connected. connection, cannot realize hinged connection, meanwhile, its loading device can only realize vertical loading, these factors limit the diversification of its experimental functions

At the same time, the above two space experimental devices cannot provide out-of-plane support for the experimental structure when implementing the planar structure experiment.
