Abstract

The paper refers to some experimental research activities carried out with a view to accommodate the functional parameters of a laser controlled system with the actual horizontal grading conditions (the slopes in x and y directions of the grading plane are null). Experimental research activities were carried on a device which comprises two electrohydraulic servomechanisms: one mechano-hydraulic servomechanism, which the quota laser sensor is mounted on and simulates the land profile; one electro-hydraulic laser controlled servomechanism, identical with the one on the machinery, which traces the first servomechanism and brings the quota laser sensor back into the optimum reference plane (generated by the rotary laser generator) whenever this one is offset of the laser plane. Experiments were meant to determine: the dynamic of the tracing laser controlled system for various land profiles; the stability and response time of this system; the dynamic of the tracing laser controlled system under simulating external noise comparable with the vibrations generated by the grading machinery.
