Actor Networks

Research involved with Actor-Network Theory (ANT) application in engineering domains often crosses through its fundamentals. In fact, exploring trends that envisage ANT as a paradigm that can prove valid in the engineering design field, researchers sometimes enrol in discussions that drive them to its roots. Obligatory Passage Points (OPP) and Immutable Mobiles (IM) are two of the fundamental concepts that need to be revisited. These concepts are critical to understanding innovation in Actor-Networks, especially for the part of IMs. In the pursuit of that understanding, the authors opt to entangle ANT and engineering design and explore a framework based on Programs of Action where actors are represented as taxonomies of competences. These actors are hybrids but, when human, they are mainly engineers engaged in the scope planning and resource management in engineering design projects or processes. This article exercises and develops a constructive process towards a methodology to approach innovation in engineering design. This research is useful for the first stages of the project design process and, in a broader way, to the full cycle of the engineering design process.

Capstone Design

The assessment of Student Outcomes is an import component for program evaluation and improvement. Though not proposed as the only tool a program should employ to measure the achievement of outcomes, the capstone design course can be a valuable mechanism to measure performance with regards to Student Outcomes. Because of the expansive reach of the engineering design process, capstone design projects present a natural environment to structure assessment activities that directly map to Student Outcomes. This paper presents versions of the Mechanical Engineering capstone design course that have been specifically structured to assess achievement of Student Outcomes commonly included in engineering accreditation criteria. Typically the outcomes are assessed by assignments that guide the engineering design process.

Concepts of precision engineering design process for optimal design where engineering sciences contribute in the successful good design are elaborated in this paper. Scientific theory, numerical methods and practicality are discussed in this paper. Factors necessary for a complete product or systems design are detailed and application of mathematical design optimization in producing a good design are shown. Many applicable engineering design examples are itemized to show relevancy of the optimal design theory to engineering design. Future trends of optimal design with respect to the 4th industrial revolution of digitization is presented. Paper sets to elaborate that most of the engineering and scientific design problems can be optimized to a good design based on many new/advanced optimization techniques.

Neutron Converter

The article discusses methods for optimizing the design of the Neutron Converter research plant design with parameters that are most suitable for a particular consumer. 38 similar plant structures with different materials and sources were calculated, on the basis of which the most optimal options were found. As part of the interaction between OKBM Afrikantov JSC and the Nizhny Novgorod State Technical University named after R. E. Alekseev, the Neutron Converter research plant was designed and assembled. The universal neutron converter is a device for converting a stream of fast neutrons emitted by isotopic sources into a "standardized" value of flux density with known parameters in the volume of the central part of the product, which is the working part of the universal neutron converter. To supply neutron converters to other customer organizations (universities, research organizations and collective centers), it is necessary to take into account the experience of operating an existing facility, as well as rationalize the design process of each specific instance in accordance with the requirements of the customer.

Floor System

Under high gravity loads, steel double-beam floor systems need to be reinforced by beam-end concrete panels to reduce the material quantity since rotational constraints from the concrete panel can decrease the moment demand by inducing a negative moment at the ends of the beams. However, the optimal design process for the material quantity of steel beams requires a time-consuming iterative analysis for the entire floor system while especially keeping in consideration the rotational constraints in composite connections between the concrete panel and steel beams. This study aimed to develop an optimal design method with the LM (Length-Moment) index for the steel double-beam floor system to minimize material quantity without the iterative design process. The LM index is an indicator that can select a minimum cross-section of the steel beams in consideration of the flexural strength by lateral-torsional buckling. To verify the proposed design method, the material quantities between the proposed and code-based design methods were compared at various gravity loads. The proposed design method successfully optimized the material quantity of the steel double-beam floor systems without the iterative analysis by simply choosing the LM index of the steel beams that can minimize objective function while satisfying the safety-related constraint conditions. In particular, under the high gravity loads, the proposed design method was superb at providing a quantity-optimized design option. Thus, the proposed optimal design method can be an alternative for designing the steel double-beam floor system.

Abstract As engineering design is subjected to increasingly formal study, an informal attitude continues to surround the topic of iteration. Today there is no standard definition or typology of iteration, no grounding theory, few metrics, and a poor understanding of its role in the design process. Existing literature provides little guidance in investigating issues of design that might be best approached in terms of iteration. We review contributions of existing literature toward the understanding of iteration in design, develop a classification of design iteration, compare iterative aspects of human and automated design, and draw some conclusions concerning management of iteration and approaches to design automation.
