Mathematical modelling of steering mechanism link vibration process in a low power tractor

Abstract

Engine, transmission, chassis and implements of the aggregated agricultural machinery are the main sources of vibration in the mobile agricultural machine. High vibration levels influence the person, who works on agricultural tractor, through driving control and steering mechanism. When driving tractor person accumulates vibrations, feels discomfort, his working-capacity decreases. Information about vibroacustic properties of tractor steering mechanism links in always helpful to decrease the vibration generated by driving control and steering mechanism elements. Some of the vibroacustic properties can be used in practical solving of vibration related problems. The article presents investigation of steering mechanism links vibrations in agricultural wheel - tractors and their possible mathematical modelling. Mathematical model of vibration phenomenon in the steering mechanism link is developed with the purpose to determine the vibroacustic properties. Steering mechanism link vibration in low power agricultural wheel-tractor and its possible mathematical modelling are analysed in the article. The developed mathematical model of the mechanical system vibration can be used to calculate longitudinal and transversal vibrations, frequency functions of vibration amplitude and to analyse the influence of construction elements on this process.
