Mechanical systems composed of components can form highly complex 3D structures in terms of the number of components, their shapes, arrangement, and material structure. Additionally, these mechanical systems often perform kinematic motions during operation, ranging from simple linear movement to complex general spatial motion. Structurally complex mechanical systems are often challenging to describe verbally, visualize, and explain the relationships (forces, velocities, stresses, temperatures) between components, and prepare technological and assembly processes during teaching. Among Computer-aided technologies (CAX) systems and augmented reality (AR), there are support modules and applications that enable essential 3D visualization not only of the shape of components and their mutual arrangement but also of kinematic motion, force effects, and more. The authors use supporting tools to facilitate the teaching of complex mechanical systems by demonstrating examples of kinematic mechanisms and the use of augmented reality in gearbox assembly. AR is an emerging technology with significant potential for interactive simulations and visualization of both complex and simpler mechanical systems. It is well-suited for streamlining the educational process and can be a tool for increasing student engagement and deepening their understanding of technical details.
