Real-time Load Determination of Wheel Loader Components

Brinkschulte, Lars; Hafner, Julian; Geimer, Marcus

Abstract:
The lifecycle costs of systems are moving more and more into the focus of machine manufacturers to ensure competitive edges and strengthen customer relations. This results in development goals such as higher avail-ability, maintenance intervals according to requirements, and minimized outages and downtime costs.
Mobile machines are subjected to loads which, occasionally, are characterized by the working task, the environmental boundary conditions and the operator. In practical use of mobile machines, some operators are not very experienced in handling a machine, for instance when using machines in the construction industry. In these cases, performing the job enjoys priority over the state of a machine and its service life. The situation is aggravated by the fact that entrepreneurs, especially in the fields of add-on and special machines, prefer to use leased vehicles, thus the operators are confronted with new machines all the time. Because of the individual control characteristics of operators, this results in permanently changing sequences of motions and load situations for the machine. The high loads occur frequently in operation and can lead to premature failure of a machine. ... mehr
