Repairability Assessment of Vehicle New Model Line-Up Using Modeling and Virtual Reality

The increasingly sophisticated design of modern vehicles affects the technological processes of assembly, repair and maintenance. When assessing the vehicle maintainability, nuances may arise at the operation stage that were not taken into account in the design, especially for new and modernized models. So, problems may arise associated with the non-optimal organization of the repair technological processes or with their injury hazard. Therefore, there is a need for feedback from the manufacturer, who has effective tools for checking and adjusting processes. An algorithm for the technological process of assessing maintainability has been developed, which includes a sequence of actions by designers and technologists and then checking the corrected process in the service center. The use of simulation and virtual reality tools allows to achieve one of the main tasks of any enterprise - ensuring the safe labor of workers, preventing injuries at the workplace. On the other hand, the correct organization of labor increases the productivity of workers and saves time significantly. Simulation of the technological process of removing the crankcase protection has been carried out. We took into account the anthropological parameters of real workers. As a result of optimization experiments, the parameters of the lift were selected, they will reduce the load on all muscle groups, thereby preventing the occurrence of occupational diseases.
