摘要
基于信息熵中模糊性度量与随机性度量相等可实现模糊变量等效为随机变量的原理,把轴心压杆的模糊临界失稳强度等效为随机临界失稳强度,把轴心压杆的载荷视作服从正态分布的随机变量,对轴心压杆模糊临界失稳强度的安全系数与模糊可靠度进行了探索。
Based on the information entropy theory that fuzzy entropy is equal to random en- tropy,the fuzzy variable will be equivalent to random variable.For axes pressure bar,fuzzy critical strength in buckling variable will be e- quivalent to random variable when load of axes pressure is a random variable with normal distri- bution.It is quantitative analyzed that fuzzy reli- ability and safe factor of fuzzy critical strength is in buckling.
