CHARACTERISTICS OF LATERAL REACTION AT CHANGE OF TECHNICAL CONDITION OF SHOCK ABSORBER

Abstract

The article presents an analytical study of the influence of the technical condition of the shock absorber on the characteristics of lateral reaction change in the spot of contact of the elastic tire with the support surface. The process of moving the car around a circle with passing along a single road ledge is the object of research. The change in lateral reaction over time is a diagnostic parameter for monitoring the technical condition of the damper. Sensitivity and unambiguity of diagnostic parameter are calculated. Purpose. The theoretical justification for the method of diagnosing a car’s suspension depending on changes in lateral reactions at the point of contact of the wheel with the road. Methodology includes numerical methods for solving differential equations, methods of mathematical modeling and mathematical analysis. Results: the mathematical apparatus for an analytical research of sensitivity and unambiguity of lateral reactions of the car at change of parameters of technical condition of shock absorbers. Practical implications: organizations and institutions that develop vehicle diagnostic techniques can use the results.
