众所周知,优化设计,始于60年代。它是由计算机专用分析程序和数学规划方法联姻而产生的。目前,虽然在理论方面有了较大的进展,但在实际应用方面范围并不广。这主要是由于它的复杂性和困难程度远比结构分析大,而一般工程技术人员在这方面的数学基础尚不完备,有的就是对某种数学规划方法较熟悉,但对另一种数学规划方法却不在行,即使后一种方法可能更有效和简便。另一方面,一个优化设计远非仅是一个纯数学题,它考虑的因素很多,要求符合实际的可能,如材料规格的离散性、构件的统一性、制作和安装的方便性等。此外,作为一种结构,又必需满足强度、刚度和稳定等约束条件。因此要真正优化一个结构的设计,所花的机时很长,费用很大,计算机周
As we all know, the optimization design began in the 1960s. It is produced by the marriage of computer-specific analysis programs and mathematical planning methods. At present, although there has been considerable progress in theory, it is not widely used in practical applications. This is mainly due to the fact that its complexity and difficulty are far greater than structural analysis. The mathematical foundations of general engineering and technical personnel in this area are not yet complete. Some of them are familiar with certain mathematical planning methods, but they are also Planning methods do not work, even though the latter method may be more efficient and easier. On the other hand, an optimization design is far more than just a pure mathematics problem. It considers many factors, and requirements are in line with practical possibilities, such as the dispersion of material specifications, the unity of components, and the convenience of production and installation. In addition, as a structure, it is necessary to satisfy constraints such as strength, stiffness, and stability. Therefore, to truly optimize the design of a structure, it takes a long time and costs a lot.
