摘    要:使用盲数表达优化设计中的不确定变量,结合常用的基于实数变量的优化算法,提出了基于盲数的优化方法.该方法从微观的角度分析和描述设计变量与优化参数之间的关系,给出优化问题的盲数解.盲数解不但给出了设计变量的取值,而且还给出了不同取值时优化对象处于最优状态的可靠性的评价.

Abstract:An optimization method based on blind number was presented with blind number expressing the uncertain variables in optimization and in combination with the traditional optimization algorithm which based on the real variables. In the microscopic point of view, the relation between design variables and optimization parameters was analyzed and described, and the blind number solution was provided. The blind number solution not only provided the values for design variables, but also provided the evaluation of reliability of the optimization object in optimal condition when the design variables had different values.
Keywords:mechanical optimization design  optimization method  blind number  uncertainty  optimization method  program  half shaft
