Abstract

A special class of general inequalities has been identified that provides the opportunity for generating new knowledge that can be used for optimising systems and processes in diverse areas of science and technology. It is demonstrated that inequalities belonging to this class can always be interpreted meaningfully if the variables and separate terms of the inequalities represent additive quantities. The meaningful interpretation of a new algebraic inequality based on the proposed general class of inequalities led to developing a light-weight design for a supporting structure based on cantilever beams, reducing the maximum force upon impact, generating new knowledge about the deflection of elastic elements connected in parallel and series and optimising the allocation of resources to maximise expected benefit. The interpretation of the new inequality yielded that the deflection of elastic elements connected in parallel is at least \(n^{2}\) times smaller than the deflection of the same elastic elements connected in series, irrespective of the individual stiffness values of the elastic elements. The interpretation of another algebraic inequality from the proposed general class led to a method for decreasing the stiffness of a mechanical assembly by cyclic permutation of the elastic elements building the assembly. The analysis showed that a decrease of stiffness exists only if asymmetry of the stiffness values in the connected elements is present.

生成新知识和优化系统和过程设计的一类代数不等式
已经确定了一类特殊的一般不等式,它提供了产生新知识的机会,这些新知识可用于优化不同科学和技术领域的系统和过程。证明了当不等式的变量和分项表示加性量时,该类不等式总能得到有意义的解释。基于所提出的一般不等式类的新代数不等式的有意义的解释导致了基于悬臂梁的支撑结构的轻量化设计,减少了冲击时的最大力,产生了关于并联和串联连接的弹性元件挠度的新知识,并优化了资源分配,以最大化预期效益。对新不等式的解释表明,无论弹性单元的单个刚度值如何,平行连接的弹性单元的挠度至少比串联连接的相同弹性单元的挠度小\(n^{2}\)倍。从所提出的一般类中对另一个代数不等式的解释导致了一种通过构建装配的弹性元件的循环排列来降低机械装配刚度的方法。分析表明,只有当连接单元的刚度值不对称时,才会出现刚度降低。

期刊介绍: Research in Engineering Design is an international journal that publishes research papers on design theory and methodology in all fields of engineering, focussing on mechanical, civil, architectural, and manufacturing engineering. The journal is designed for professionals in academia, industry and government interested in research issues relevant to design practice. Papers emphasize underlying principles of engineering design and discipline-oriented research where results are of interest or extendible to other engineering domains. General areas of interest include theories of design, foundations of design environments, representations and languages, models of design processes, and integration of design and manufacturing. Representative topics include functional representation, feature-based design, shape grammars, process design, redesign, product data base models, and empirical studies. The journal also publishes state-of-the-art review articles.
