Development of the Russian Standard Investigations in the Meld of Constant and Low Frequency Motion Quantities Measurements

摘要

The 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 5×10{sup}(-5)...3000m/c{sup}2, variable linear accelerations within the range of frequencies of 0.05...30 Hz and amplitudes of 10{sup}(-4)...250m/c{sup}2, variable plane angles within the range of up to 360°) 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.
