Abstract
BACKGROUND: For front-end loaders, it is important to minimize energy consumption when performing loading and unloading operations. To ensure competitive properties at a given time of folding links, lifting and with sufficient power of the steering and boom and bucket control drives. This requirement significantly affects the autonomy, versatility and, ultimately, the economic efficiency of loading and unloading operations.
AIMS: Development of a dynamic model of a front loader to determine various operational properties and loads in the joints when working in specified load conditions.
METHODS: A dynamic model has been developed and its operation has been simulated in a system for calculating the dynamics of coupled bodies. The mathematical model includes all the main elements of a front loader – drive axles, internal combustion engine, generator, steering hydraulic cylinders, cargo, bucket, rear axle, cab, wheels, bucket lifting and tipping mechanism, load-bearing system, support surface, TED drive of the driving wheels. The elements are modeled using graphical primitives, hinges and power ones from the standard library of the application for calculating the dynamics of connected bodies.
RESULTS: The article presents a description of a mathematical model of a front loader made in the application for the calculation of connected bodies. A typical list of load modes is presented and examples and simulation results are shown. Possible areas of use of the described mathematical model are shown.
CONCLUSIONS: The developed dynamic model of the front loader makes it possible to analyze various design solutions at the early stages of design, such as the model and number of electric motors, kinematics of the bucket lifting and tilting mechanism, steering kinematics, etc. for energy costs during typical operations. In addition, the developed dynamic model allows you to determine the loads in the hinges and power connections, which can be used when performing strength calculations or when selecting loader components.
