Theoretical substantiation of the parameters of the mechanism of autoresonant vibroimpact interaction of cultivator claws with soil

Abstract

Abstract It is proposed to introduce a mechanism with moving masses separated by elastic elements of different rigidity into the design scheme of the cultivator working body to ensure the self-oscillating resonant interaction of the cultivator claw with the soil. The frequencies of the main oscillations of the system with moving masses, corresponding to the range of oscillation frequencies of the cultivator claw in the soil, are determined using the oscillation theory. The oscillation frequency of the cultivator paw was determined experimentally in the soil channel. By calculation, using the obtained equations, the values of the moving masses and the rigidity of the elastic elements of the mechanism of self-oscillating vibro-impact interaction with the soil of the cultivator are found.
