Reverse engineering for spare parts of load–haul–dumpers at a mine service station

The essence and role of reverse engineering in repair of load–haul–dumpers (LHD) at foreign manufacturers are discussed. To that end, spare parts of LHD are classified into typical, unique and standardized. Based on the classification of spare parts, the reverse engineering methods are rated by the level of their complexity and labor content. The proposed algorithm demonstrates the place and role of the reverse engineering in the process of LHD repair, and makes it possible to assess possibility and expediency of application of the elaborated analog operating process of the reverse engineering for the typical and unique spare parts. As a result of the study, the function-and-information modeling of the reverse engineering was performed for a sample of an original part using methodology Icam DEFinition for Function Modeling. The latter model is developed for the decomposition and system description of the reverse engineering process, and for determining all input and output data, necessary human and material resources, as well as controlling mechanisms, limitations and standards at each stage of the reverse engineering. By way of illustration of application of the analog operating reverse engineering process at a repair station of a mine, the reverse engineering of a hydraulic cylinder piston of LHD is described. This example illustrates the spare part drafting using a real sample to manufacture an analog spare part to replace the absent original part of LHD during its maintenance support.
