Abstract

In the process of teaching Strength of Materials, students often find it difficult to understand and the level of achievement of the course learning outcomes is not high. Therefore, active teaching methods and application of computer aim to support students actively, proactively, and in project-based learning. This article presents the possibility of integrating the Mdsolids software in teaching strength of materials at Nguyen Tat Thanh University (NTTU) for students majoring in automotive engineering technology. The student satisfaction survey on the course and the application of Mdsolids in teaching were conducted and evaluated to test the effectiveness of active learning activities. The obtained results confirmed further evidence of the benefits of Mdsolids in supporting students to achieve the course learning outcomes.

Abstract

This study presents the design, fabrication, and evaluation of a hybrid electric scooter frame constructed from laminated Gombong bamboo and aluminium. The objective was to address environmental concerns in personal mobility by reducing reliance on high-carbon materials and improving battery safety. A CAD-based design was executed in Autodesk Inventor using bamboo beams for primary structure and aluminium joints for mechanical stability. Laminated bamboo was processed through drying, chemical treatment, and gluing. Mechanical properties were evaluated via tensile and compressive tests, achieving a tensile strength of 289 MPa. A 72V lithium-ion battery pack composed of 18650 cells was assembled with BMS integration. The resulting prototype exhibited a total frame weight of 4.8 kg and a 30 km range per charge. The integration of laminated bamboo with aluminum joints provides preliminary evidence of feasibility and highlights bamboo’s potential as a renewable material for lightweight mobility applications. These results provide an initial prototype-level demonstration of laminated bamboo as a viable material for sustainable transport applications.
