摘　　要：薄板铝合金材料常采用气淬方式进行加强,但由于零部几何形状差异较大,气淬后强度很难达到手册值要求。而设计环节往往是按照手册值进行强度校核,虽有一定的安全余度,但产品是否真正安全,急需研究。通过强度干涉理论和试验测试相结合,通过仿真分析的方法进行安全余度量化。总结出一条在设计环节即可进行安全性评估的方法,希望此方法为后续产品的设计,起到抛砖引玉的作用。The aluminum alloy sheet material is often strengthened with gas quenching method,but gas quenching strength isdifficult to achieve the manual requirements due to different geometric shape of parts. The strength check in design part is of-ten conducted according to the manual value,although there is certain safety margin,it is necessary to study whether the prod-uct is really safe. In this paper,combining the strength interference theory and experimental testing,quantization of the safemargin is conducted through the simulation analysis method. Finally a safety assessment method that can be carried out at thedesign part is summed up so as to start a dicussion on design of the following products.
