^4fDevelopment of the Russian Standard Investigations in the Field of Constant and Low Frequency Motion Quantities Measurements

摘要

^7fThe main lines of the works in the field of development of high accuracy standard setups for reproducing the motion quantities, (constant linear accelerations within the range of 5x10~(-5)...3000 m/c~2, variable linear accelerations within the range of frequencies of 0,05...30 Hz and amplitudes of 10~(-4)...250 m/c~2, variable plane angles within the range of up to 360~0) are considered. A distinguished feature of the standard setups is the possibility to reproduce with the help of only one setup a number of physical quantities or one quantity both in static and dynamic modes. A general model to determine the equation for measurement and evaluation of the components of uncertainty of the quantities reproduced. A design of the developed standard setups and results of their metrological investigation and certification are given. Moreover, a direction of future investigations in this field of measurements is discussed.
