A method of assessing the axle of passenger cars using the standardized adhesion method

摘要

the invention relates to the method of evaluation of passenger cars by standardised adhesion used for transformation of signals measured in the current eusama test.the test wheel is subjected to vibration adhesion test and recorded in memory of computer signal sensor contact force wheel to kmitaju00edcu00ed platformto obtain the dependence of contact force wheel time and subsequently the values of static and the minimum contact force wheels is calculated relative to kmitaju00edcu00ed downforce round platform.obtains the frequency dependence curve envelope ac dynamic components on the frequency of vibration platform, to evaluate the resonance frequency and the maximum value of the dynamic forces at this frequency.subsequently, the approximate value of measurements is calculated and the calculated value of the attenuation transmission functions for the angular speed.calculate the approximate value of the immediate rigidity of the tyre at the absolvovanu00e9m test and calculate the static deformation of the standardized adhesion for tyrewhere the static deformation tyre is 6,66 multiple value amplitude of the tester.according to the invention, the method allows to unify the results in severe resonant adhesion testers with different books.
