摘要
由于结构试验试件结构形式复杂多变、受力状况复杂,大型结构试验反力架的设计需充分考虑试件的结构形式、试件受荷状况、试验场地的环境、经济性等因素,是一项复杂的结构设计.设计了加载能力达50 MN的三维空间钢结构反力架,并用大型有限元软件ANSYS对反力架进行了静力分析,揭示了反力架在竖向最大模拟加载情况下应力、变形分布情况,找出反力架在强度和刚度设计上的薄弱环节和富裕部位,为大型结构试验反力架设计和优化提供依据.
Because of the complexity of the structure and the stress state of the test specimen,the designing of the large counterforce frame structure should give full consideration to the structure of the specimens,the specimens' load conditions,the test site environment,economy and other factors,it's a complex structure design.The paper designs a three-dimensional space steel counterforce frame with the load capacity of 50 MN,and the static analysis has been carried on the frame by using the largescale finite element software ANSYS,reveals the distribution of the stress and deformation when the counterforce frame is under the maximum vertical load,finds out the weak links and rich place of the counterforce frame on the strength and rigidity design,provides the basis for design and optimization of the large structure counterforce frame.
