FIELD: transport engineering; railway transport. SUBSTANCE: to connect vehicle members use is made of carrier with nonlinearly changeable rigidly and frequency of natural oscillations of vehicle system members are changed. Carrier plays the part of resilient tie according to equation P = [a+b[Δ+δ/2)c+(Δ-δ/2)c/m]0,5 where m is mass of bolster suspension and car body members corrected to carrier; a, b, c are coefficients of carrier rigidity nonlinearity; δ is displacement of members coupled with carrier along vehicle; Δ is preload of elastodeforming member of carrier. EFFECT: prevention of resonance. 2 cl
