Perederko A. Model and the system to improve the accuracy of the coordinate measurement by protecting against vibration effects

The object of research is the process of active anti-vibration effect of precision measuring systems for the control of geometric parameters of products. The subject of the study are methods and means of protection against vibration effects on nondestructive testing instruments (precision coordinate measuring system) with the use of active vibration isolation. First, a mathematical model of measurement error in the control of geometrical sizes of products on the VCR, which in contrast to the existing ones, it takes into account the dependence of the magnitude of the effects of vibration impact of the environment (the amount of acceleration, complex time series of the self and the forced oscillation frequency), thus improving the accuracy of measurements and the accuracy of the control. First built by the active vibration dampers, which, in contrast to the existing uses the change in the stiffness of the elastic element and the dependence of the optimal values ??of the damping ratio of stiffness, which allows to automatically prevent resonant modes and improves the accuracy and reliability of kontrolyu.Vpershe developed a method of protecting a VCR with the implementation of the measuring control parts, which in contrast to the existing uses piezoelectric actuators that allowed us to construct an active vibration isolation system to ensure high performance and small phase shifts in the suppression of vibration impacts the environment and thereby increase the probability of measuring control.
