一种评估火箭结构设计的新方法

在火箭结构优化设计时，常采用一个简化的标准或目标函数（如全应力、最低费用）着手设计。介绍了一种新方法，允许设计人员对各判据用加权处理来评估候选的设计。这些加权系数可随目标程序的变化而变化。该方法可对结构设计作出客观的评价。

A New Method for Evaluating the Design of Rocket Structure

Many engineers usually utilize a simplified criterion or objective function (e.g.full stress,minimum cost) to optimize the design of rocket structure. The paper presents a new method for evaluating candidate design, which allows designers to assign weights to the various criteria.The weights can be altered as the objective programs change.An objective judgment for rocket structure design can be made by the method.
