Study of the Characteristics of Vertical Vibrations of a Truck Suspension in Stden Conditions
Keywords:
frequency, amplitude, model, damperAbstract
The article presents the results of experimental and analytical research on the influence of the coefficient of spring dampers of a pneumatic axle of a truck on the characteristics of vertical oscillations in the dynamic system “pneumatic eye - suspension - spring mass”, which is simulated on a stand. By compiling a mathematical model of the system and solving it, an image of the amplitude-frequency characteristic of vertical oscillations of the spring mass was obtained, using which it was established that the influence of changing the coefficient of spring dampers on the oscillations of the spring mass is clearly manifested only in the resonant frequency ranges, in other cases this influence is insignificant.
