摘要
在非概率可靠性理论和优化设计方法基础上,考虑压杆稳定设计中材料弹性模量和所受载荷具有的区间不确定性,讨论了压杆稳定可靠性优化设计问题,提出了压杆稳定的非概率可靠性优化设计方法。算例及其结果表明模型和方法具有一定的理论意义和实用价值。
Based on non - probabilistic reliability theory and the optimization design method, considering the interval uncertainties regarding elasticity modulus and loaded force, stable non - probabilistic reliability - based optimization design of compressive bar is discussed and a method for stable non - probabilistic reliability based optimization design is proposed. Numerical examples and the results show that the model and method proposed have some theoretical significance and practical value.
