| Abstract | For the operator the excavator control task is an accurate visual-motor tracking that, apparently, can be viewed as a biomechanical problem of kinematic motion. Its solution has a number of limitations but the multidimensionality of the working limb and control lever — joystick is leading among them. The creation of a universal biomechanical model with such a large number of independent motions that are implemented with separate power sources is difficult. However, the biomechanical approach based on the experimental determination of linear and angular displacement, velocity and acceleration, the radius of curvature and surface of motion, etc., is quite successful to solvе specific motor problems and to create methods for synthesis of kinematic parameters of the master devices of manipulators. But the most appropriate solution of the problem to estimate the accuracy of the control of the proposed system is using a stand study. On the simulating bench the operator performs the test task of motor control that is implemented by means of electro-hydraulic simulator to be developed. This approach aims to assess the stability of the man-machine system behavior under different influences, vibration, for example, while changes in both the visual and motor systems occur. Analysis of the motor regulation mechanisms using a computer model for controlling the human uniarticular motion by shifting the equilibrium point (Chernavskii et al., 1998) would clarify the nature of the vibration effects on the motor control. |
