Innovative Design of Compact Heavy-Load Independent Transfer Device for Nuclear Engineering System

Abstract

The transportation of heavy equipment in nuclear engineering has always been the focus of engineers, especially those transfer devices with the characteristics of small geometric size and heavy load. According to this kind of compact heavy-load transfer device and its engineering tasks, the core problems caused by excessive vertical and horizontal forces in the design process were analyzed. By introducing the theory of inventive problem solving (TRIZ) design method, these problems were creatively solved by the contradiction theory and substance-field model in TRIZ, and an innovative design scheme of the compact heavy load-independent transfer device was obtained. Through the analysis of the design scheme and the stability and rapidity of its hydraulic system, some key parameters were determined. The power of the transfer device was all from the hydraulic system, and it can carry up to 300 t weight of reactor equipment, while its geometric size was only 1600 × 400 × 500 mm. It was of great significance to improve the efficiency of the nuclear engineering system.

Application of the AIR learning model using song media to improve students’ mathematical representational ability

“…The Auditory Intellectually Repetition (AIR) learning model is said to be successful because it emphasizes three learning factors, namely Auditory (Christine et al, 2020), Intellectual (Septian, 2020), and Repetition (Song & Kim, 2022). Learning to listen (Wan et al, 2022), pay attention (Wang et al, 2023), speak (Liu et al, 2013), express opinions (Zhang et al, 2022), respond (Rhodes et al, 2022), present (Mukai et al, 2018), and explain all takes place at the Auditory stage, which involves the sense of hearing. At the intellectual stage, thinking skills must be developed through presenting data into mathematical models through reasoning, construction, applying ideas, asking and answering questions, and solving problems.…”
