Исследования колебаний тракторов, оборудованных пневморессорной и серийной подвесками при движении по грунтовой дороге

Abstract

The analysis of the numeral data, got as a result of realization of comparative experimental researches of smoothness of motion of tractor unit on the base of the wheeled tractor equipped by different types of the suspension systems of front bridge, as follows a serial spring suspension, air spring suspension with additional reservoirs without shock absorbers and air spring suspension with additional reservoirs with shock absorbers when moving on road with dirt covering. Dependences of change of root-mean-square accelerations of seat of driver, root-mean-square vertical and horizontal accelerations flap booths, root-mean-square accelerations of the frame on front bridge, root-mean-square accelerations of the speedups front and back bridge as well root-mean-square of the relative moving the frame and front bridge are set in octave stripes, corresponding to geometric mean frequencies 1 Hz, 2 Hz, 4 Hz, 8 Hz and 16 Hz at motion on transport number gear box.
