Abstract
This paper presents a method for establishing a general model which enables to simulate tractor’s turning process and calculate its main characters in considering basic characteristics of engine, transmission system andinteraction between tyre wheels and flexible base pavement. The mathematical model which describes approximatively working characters of the farm tractor, can display general image for the ralation of kinetic and dynamic parameters when a farm tractor moves on the deformation ground. The boundary condition and the input parameters of the model can be defined from experimental studies.The built model has been applied in order to investigate qualitatively and quantitatively by digital computer the effects of some structure parameters and working condition on turning capacity of several popular farm tractors in Vietnam.
