ABSTRACT
The thesis, analyzing the dynamics, stability cornering of the 100 tons super heavy, super long tractor ± semi trailer has been done by the author The tractor ± semi trailer is called TST which included a 04-axle tractor connected to an 08-axle trailer at the rear The TST model is referred to as a series equivalent to controlling the tractor steering wheel with a semi-sinus steering function and the movement speed of 30km/h The semi-trailer rear axle wheel is steered in three cases with the same direction, opposite direction and no steering wheel compared to the tractor steering wheel The research is done on the basis of combination theory using Matlab software for simulation The research results of the thesis evaluate two main aspects: the value of the horizontal force acting on the tires and the turning space In addition, the author also mentioned and analyzed some other important dynamic and kinetic parameters such as variation in lateral speed, angular velocity, variation angle between tractor and trailer over time From the research results, we can see the advantages and disadvantages of the rear wheel drive cluster of the semi-trailer cluster in terms of the mentioned survey aspects From there, it serves as a basis for application in designing as well as manufacturing actual products with specific objects of super heavy, super long tractor ± semi trailer
