Maintainability Approach: Hydraulic Pump with External Gears Explored with Design for Disassembly and Augmented Reality

The work carried out has the purpose of improving and optimizing various industrial technical operations, such as preventive maintenance, taken here an example application, using Design for Disassembly (DfD) technique. Therefore, through four metaheuristic methods that have been chosen among most widespread in field (described below) to make a comparison between them, optimal disassembly sequence is sought, if it exists, terms time then costs order extract target component without damaging other mechanical parts assembly. hypothesis tested throughout this case study “a responsible application DfD, not only from design process product but also during procedure, can bring substantial benefits company”. Interaction with hypothetical operator charge be performed implemented use augmented reality. In fact, programmed Android device (in case, mobile phone, hence handheld device), instructed step-by-step on dynamics animation. Finally, two virtual buttons were added reality which start pause/resume animation at any facilitate understanding different steps established by sequence.
