摘　　要：讨论了金属材料受载时弹——塑性非线性变形理论和曲线,将材料的真实应力——应变曲线简化为双线性强化弹塑性曲线,并对曲线参数进行了计算。以压缩机底座为例,提出非线性材料零件的建模、分析、设计的方法,并对此模型的压缩机底座结构参数进行设计。Discussed the disciplinarian of metal elastic-plastic deformation when it is loaded. Simplified the curve of metal real stress-strain to a Bilinear Kinematic Hardening elastic-plastic curve, and calculated the parameters of stress-strain curve. With compressor pedestal as an example, an approach of modeling, analysis and design of structures which being made of nonlinear material is proposed, and structural parameters of pedestal are designed with the finite element model.
