Teaching System of Hydraulic Transmission Combined with Virtual Reality Technology

Abstract

Traditional hydraulic drive experiments present a number of challenges. During the hydraulic transmission experiment, the equipment is easily damaged and must be frequently updated, which makes it difficult for a large number of students to study at the same time; the traditional offline, monotonous, and boring experiments make it difficult for students to increase their interest in learning from what is inherent; and most undergraduate students have to study at home due to the impact of COVID-19. Therefore, students need an excellent teaching system that allows them to perform experiments at home and improve their learning efficiency. A teaching system for the undergraduate hydraulic transmission course was designed to meet the needs of the hydraulic transmission course and to stimulate students’ interest in learning. This teaching system allows students to spend more time outside of the class to analyze experimental results and relate concepts presented in lecture courses to experimental results. Finally, a course on hydraulic drives taught at Nanchang University was used to evaluate the effectiveness of this teaching system. The analysis based on positive student feedback and academic performance shows that the proposed teaching system is an effective learning tool for undergraduate students in their learning process.
