Analysis of the Kinematic Characteristic of the Test Stand for Various Steering Systems for the Hydraulic Driven Working Attachment.

The steering system for working machines attachment is a mediator between operator and the environment, thus it is one of the main factors which influence the efficiency and safety of the operator's work. The subject of this article is the test stand which enables one to test various steering systems for the hydraulic driven working attachment. The test stand is designed and already build by authors. The close representation of the real working attachment manipulation conditions as well as the ability to connect various steering systems to it were the main design criterions. The first one was obtained by imitation of the maximal angular range and the maximal angular speed of the boom and the stick from the real working machine. The micro-controller ATmega 32 was used as a supervisory system of the mechanical arm. This solution grants the test stand the ability to attend various steering systems without major changes of its construction. [ABSTRACT FROM AUTHOR]
