Determining the optimal parameters of a single-bucket excavator based on operating conditions

Abstract

The technical characteristics of a machine are documents containing information on its technical specifications, operation, ergonomics, and environmental parameters. These details enable effective decisionmaking regarding the machine’s use for performing necessary technological operations, depending on operating conditions. The main parameters include parameters that determine the maneuverability, working capacity, main working dimensions of the machine, as well as their reliability. For a single-bucket excavator, the key parameters primarily define its technological capabilities, such as machine weight m,machine power N, and bucket capacity q. Selecting these parameters for a new machine during the design process is a crucial techno-economic task. Solving this problem ensures the development of machine systems and complexes that enable efficient comprehensive mechanization of earthmoving operations. As an objective function in parameter optimization, both technical and operational indicators are considered, including cycle time and technoeconomic efficiency criteria. This paper presents the results of determining the optimal parameters of a single-bucket excavator based on operating conditions.
