Differential equation of truck semitrailer transverse-angular oscillation

Abstract

Differential equation of cross-angle oscillations of the semitrailer truck, derived from the analysis of vibration of its elements is described in the paper. Lagrange's equation is used as the basis of differential equation of cross-angle oscillations of the semitrailer truck. Based on the derived differential equation, an equation for determining the oscillation frequency of the cyclic platform of semi-trailer truck hitting the uneven road surface is derived, which allows conducting the theoretical study of the dynamics of motion.
