摘　　要：根据工程实际问题抽象简化,研制了平面桁架结构稳定性实验装置。此实验装置结构紧凑、操作方便。应用此装置开设的结构稳定性实验,因约束形式多种,杆件长度可变,从而形成了不同的力学模型和失稳形式,这对于加强学生综合实践能力培养、深化学生对结构稳定性的理解、评价和思考具有重要的意义。The plane truss structure stability experimental device is developed according to simplified practical engineering problem. The experimental device has the advantages of compact structure, con- venient operation. By using the device, the experiment of structure stability is provided, because of dif- ferent constraints, the member length variable, thus forming different mechanical model and instability modes, which is to strengthen the students＇ comprehensive practical ability, deepen their understand- ing of the structure stability, evaluation and thinkin~ hn~ imnn,-tnnt ~i,m;r,
