Zharko J. Improvement of measurement uncertainty evaluation proce-dures during certification testing of wheeled vehicles

The object of research is the process of testing motor vehicles the parameters of structural safety.  The aim of the thesis is to improve test methods for wheeled vehicles parameters constructive security by developing evaluation procedures uncertainties vymiryuvan. Scientific novelty of the results: For measurement methods structural safety parameters during tests wheeled vehicles was first realized standardization of measurement uncertainty estimation procedures on the basis of the feasibility of using statistical evaluations of measurement uncertainty and descriptive statistics, elected as the measured value, which made it possible for different procedures to give mathematical tools and make recommendations for its use; The model parameters measuring structural safety by taking into account all input variables that affect the result of measurements on which first obtained the mathematical expression for the total estimates of standard and extended measurement uncertainty structural safety parameters during tests wheeled vehicles; For the first time received estimation of measurement uncertainty by type A maximum value of several measurements, a comparison of their efficiency in the calculations because the formula Bessel and through swing sample depending on the number of measurements, due to what was first developed procedures uncertainty of radioelektrychnyh interference from ignition systems and external noise fixed wheel vehicles.
