| Summary: | When using a machine-tractor unit, external conditions of its operation change in a wide range. It results in frequent changes in the parameters of speed and load modes of its power plant. Resulting vibrations and oscillations in addition to discomfort and excessive loads on components and mechanisms of the power plant also cause fuel overspending and power losses. To reduce negative vibration impact on effective performance of the power plant creation of supports with adjustable characteristics is suggested. Both internal unbalance of the power plant itself and external influence of variable moment of resistance and impulses of supports themselves are considered perturbing moments. Changes in rigidity and damping coefficients of relevant supports can reduce the amplitude of oscillations of the power plant in variable operating modes, which will improve its utilization indicators. |
