ELIMINATION OF VIBRATIONS ON AGRICULTURAL MACHINES USING DISCRETE MEDIUM: MODELLING AND EXPERIMENTAL STUDIES
The article is devoted to the problem of protection of self-propelled vehicles, tractors, harvesters and other structures from vibration. Installation of dampers and vibration damping materials cannot completely eliminate vibration exposure. As protection from vibration and beat the discrete mediums with good dissipative properties in a wide frequency range are offered for using. The damper on discrete mediums is more simple in manufacturing and tuning in comparison with the usual one-mass of the vibration damper. The mathematical model of vibration damper on discrete environments is considered in the article. The results of experimental studies of dissipative properties of the various discrete mediums are given. Different combinations of absorbers are compared. The result of the use of a damper on discrete mediums is obvious: it has broadband and stability, provides reliability and durability of the protected structure, and has a lower prime cost compared to batch multi-mass absorbers.
