This paper proposes an approach for obtaining minimum weight design subject to multiple constraints of different types (i. e., stress,displacement and side constraints) under multiple load cases. The design point is moved along the boundary of the most critical constraint by using the scaling step and then the single disp1acement criterion step (if the critical constraint is a displace- ment one) or the fully stressed criterion step (if the critical constraint is a stress one), until the optimum solution has...

This paper proposes an approach for obtaining minimum weight design subject to multiple constraints of different types (i. e., stress,displacement and side constraints) under multiple load cases. The design point is moved along the boundary of the most critical constraint by using the scaling step and then the single disp1acement criterion step (if the critical constraint is a displace- ment one) or the fully stressed criterion step (if the critical constraint is a stress one), until the optimum solution has been found. An improved techni- que. for the approximate structural reanalysis and a reduced basis technique for sensitivity analysis are presented in this paper. Numerical examples have shown that these approximate techniques are very useful and efficient in structural optimization. The approach in this paper avoids the difficulties for deciding the active and passive variables and for calculating a large set of Langrange multiplies for the active constraints, and greatly reduces the num- ber of reanalysis of the modified structure. The application of the approach to a number of truss structures has demonstrated the efficiency and accuracy of the approach. The application of this approach can be extended to the structures which consist of the membrance elements.

本文提出了桁架结构在多种荷载工况多种约束类型约束(位移、应力和尺寸约来)条件下最轻重量设计的齿行法.利用射线步把设计点拉到最严约束界面上,然后使用单位移准则步或满应力准则步来确定设计变量修改的方向和步长,直到找到一个满意的最优解为止。另外.本文还提出了修正的摄动法和敏度分析的降维法,应用这些方法于结构优化设计收到相当显著的效果.数字例题表明,这些近似的重分析方法在结构优化设计中是很有效的。 本文的方法可以用于由膜单元组成的多种单元组合结构。

本文指出了Miura 变换不仅存在于非线性发展方程中,而且存在于与之相应的特征值问题的位势之间.然后利用高阶的协调关系(?)引出“变形的李群结构方程”,并由此出发,比较自然地得到了两类非线性发展方程之间的关系,最后把这些结果推广到了矩阵的情形.

This Paper analyses the crack in tank track links end arm, and proposes a modified structure. Using 3D-element of SAP5 finite element program , we made a static compution for track link. When the tank is driven,if the track is set oppositely, the maximum effective stress will decrease from 20kg/mm~2 to 3kg/mm~2. When the track link is supported simply at the end of the tra- ck link, the maximum effective stress in the improved track link is 19kg/mm~2, but the maximun effective stress in the original is...

本文对五九式坦克履带板联接臂断裂原因进行了分析与计算,并提出相应的改进方案。应用“SAP5线性静动力结构分程序”的三维实体有限单元对履带板联接臂处迸行静力计算表明,将原履带板“反装”使前进时牵引力造成的最大有效应力由20公斤/毫米~2降到3公厅/毫米~2。进方案使最大有效应力由垫支时的32公斤/毫米~2降到倒车时的19公斤/毫米~2。因而,采用反装和改进的结构方案将会提高履带板的寿命。
