This paper is devoted to describing of method of decreasing of vibration load level on tractor operator’s working place by means of using of vibrations dynamic dampers in cabin suspension (on other words – dynamic absorbers of dynamic vibroisolators). Standard cabin vibroisolators of tractors DT and VT series include monolith rubber block and have limited capabilities to change its elastic parameters adaptively during impact of vertical and lateral vibration loads with various frequencies. Elastic-damping properties of these vibroisolators does not allow to provide comfortable conditions for operator work because their abilities of vibration damping are not enough especially at low-frequency vibrations. Dynamic vibration dampers installed in cabin suspension were proposed by authors for decreasing of vibration load level on operator workplace. These dampers include additional masses connected to main mass due to elastic-damping elements. Several variants of dynamic vibroisolators schemes were proposed by authors. These schemes differ in quantity of additional masses (one, two or three) and type of connection between additional masses and main mass due elastic-damping elements (parallel or in series). Three-dimensional model of caterpillar chassis, suspension, engine, cabin and operator’s seat of tractor was created in software “Universal mechanism” for performing of computational research. On this model, researches of vibration of sprung mass were made for tractor motion with and without hook load at 3rd and 7th gears on smooth surface and on testing areas with single, periodic and random bumps. Research results indicate undoubtedly best vibroprotective properties of cabin’s suspensions with dynamic vibroisolators.
