机械结构模拟试验中原型与模型的力学关系分析

Analysis of mechanical relation of original body and model in the construction simulation test

针对机械结构设计中模拟试验的需要 ,定义了模拟试验中的原型和模型。在模型与原型材料不同的情况下 ,建立了原型与模型间的应力场、应变场及位移场的相互转化关系 ,利用所得的转化关系将模拟试验中得到模型的力学参量直接转化到原型上 。

Aiming at the request of simulating test in mechanical construction design, the original body and model are defined.The relation of stress strain field between original body and model which is made of different materials is established.Then the mechanical parameters of model can be transferred to original body by using this relation.Calculation is made with the model of cylinder as an example.
