Problems of transport machine design and operation, which are most effectively solved within the framework of computational modeling with the use of finite element and statistical modeling methods, are systematized. The nature of the results and prospects of their use in decision-making on the optimization of design parameters and operating modes are considered.
Limitations of the mathematical theory of reliability as applied to mechanical elements of transport machines are considered. A new approach based on the use of defect statistics, results of stress state calculation, fracture mechanics apparatus and real data on transport machines loading processes is offered. Prerequisites for calculation of transport machines survivability as a further development of reliability concept are considered.
The research was carried out in the conditions of Zhdanovsky mine of Pechenganickel Combine. The object of research is a dump truck BelAZ-549 with payload capacity of 75 tons with a diesel engine 8RACH-185 with a capacity of 882 kW.
