Abstract
Vibration protection seats are widely used in the designs of modern mobile machines as one of the means of ensuring the requirements of sanitary standards for the level of vibration at the driver’s seat. At the same time, the problem of a reasonable choice of the dynamic characteristics of the seat in accordance with the parameters of the external vibrational impact and the features of the dynamic system of the machine is relevant. Modern anti-vibration operator’s seat has a rather complex design, including non-linear elastic-damping elements. Therefore, in some cases, it becomes necessary to experimentally determine its characteristics. The article is devoted to an experimental study of the dynamic characteristics of the Sibeco anti-vibration seat of the T-11 industrial tractor of the Chelyabinsk Tractor Plant. Static tests have been carried out. Nonlinear elastic characteristics of the suspension system and seat cushion are obtained. For dynamic testing, we used an electrodynamic vibration stand and information-measuring system. The amplitude-frequency characteristic of the seat was obtained, its natural frequency was determined. The damping characteristics were determined and the elastic characteristics of the seat elements were refined. According to the results of tests under random loading, the certification characteristics of the seat were determined. The obtained characteristics will later be used to create a mathematical model of the anti-vibration seat. With the help of a mathematical model, calculations will be carried out to optimize the characteristics of the anti-vibration seat.
