EXPERIMENTAL MEASUREMENT OF THE DYNAMIC MODULI OF NATURALLY AGED RUBBER SEGMENTS

Popis výsledku v původním jazyce

Subjects of experimental investigation were damping segments of Polyisoprene-Polybutadiene Rubber Blend (IR/BR) used in resilient wheels of railway vehicles. The examined naturally aged segments have different service history. The effect of aging on theresponse to dynamical loading was investigated. Specimens sliced from segments were subjected to dynamic mechanical analysis which consists in sinusoidal compressive strain controlled loading with different amplitudes and frequencies. The phase angle delta between strain and stress responses and storage and loss moduli were determined by different evaluation methods. Rubber becomes harder in course of aging, loses its damping capability, properties affecting its friction behavior change and friction coefficient is reduced in comparison with the virgin state.
