This article studies the issues of digital simulation of physical operating processes in vehicles transmission. Simulation of dynamic processes is carried out in power transmissions at the design stage. The procedure for using the digital packages such as MATLab – Simulink and Simscape was considered for the numerical simulation of dynamic processes in mechanical systems based on the example of the theoretical calculation of K-744 tractor transmission dynamics. A digital model of K-744 tractor transmission is constructed, its calculation scheme is given, the initial characteristics are determined. A digital model of the tractor engine was created by means of the Simulink package. A nature of change in tractor engine torqueis determined by it. The calculated analysis of normal transmission frequencies is performed. Forced torsional vibrations are calculated in the tractor change gearbox generated by the vehicle engine operation. The conditions of resonance in the transmission are analyzed. The unfavorable modes of joint operation of the engine and the gearbox are determined for K-744 tractor.
The present research work has been carried out with financial support from the Ministry of Education and Science of the Russian Federation in the frames of the federal targeted program “Research and Development in the Priority Areas for the Development of Science and Technology Sector of the Russian Federation for 2014-2020” pursuant to the project: “The Design Of The New Model Series Of Automated Boxes Change Gears For Agricultural And Road-Building Equipment In The Range Of 140-440 kW, Adapted For Use In Complex Systems Unmanned Tractor”(Unique Project Identifier RFMEFI57816X0213)
