Determination of the form of vibrations in vibratory plow’s moldboard with piezoceramic actuator for maximum vibration effect

Agriculture is the practice of growing plants and livestock. The task of agriculture is to supply raw materials for industry and provide the population with food. One of the main problems of agriculture is the complicacy and efficiency of soil cultivation. The plow is the main instrument for soil’s tillage in agriculture. The analysis of present-day plows is conducted and their characteristics are analyzed. The method of reducing the friction of the cultivation unit with the help of ultrasonic vibrations has been experimentally tested. For the first time, the oscillation forms of the vibratory plow’s moldboard with a piezoceramic actuator at ultrasonic frequencies are obtained. According to the results of the research, it is found that the frequencies of 36 kHz and 37.4 kHz can be chosen as the resonant ones. The influence of negative factors, such as soil sticking during its cultivation, is reduced, as well the resistance created by the soil during its cultivation is reduced. Thus, the time of plow operation is increased. When using a piezoceramic actuator, more flexible possibilities open up in the control of the vibratory plow. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
