【摘要】 用典型的三杆衍架结构设计问题，进行了结构稳健性设计与考虑不确定因素的优化设计的比较．通过用蒙特卡罗模拟法对设计结果的结构可靠性计算，表明两种设计在提高结构可靠性上是一致的，但结构稳健性设计更具有有效控制结构特性散布的优点．更多还原

【Abstract】 Through numerical calculations of a truss design problem, a comparison between structural robust design and structural optimum design with uncertainties is made. And, through the relia- bility analysis by Monte Carlo simulation, the structures designed by the two methods show the same reliability, but the robust design has the merit of controlling the structural response’s variations ef- fectively.更多还原
