Empirical experiments are being carried out in automotive industries today, in order to increase the efficiency and improve the performance of various vehicle systems. Despite the importance of experimental experiments, many problems and difficulties in conducting experiments such as high costs, inadequate precision , Safety problems, etc. Sometimes it is difficult or even impossible to perform a number of tests. Therefore, if possible tests can be performed on the drum, a number of problems can be solved. Since the tire interaction The car and road surface are highly dependent on the conditions and geometry of the surface, and it is not possible to carefully consider the existing models The flat surface when the tire is contacted with the cylinder surface (test car drama) without any changes. In the research, a model of the tire crash test device has been generalized to derive optimum results in the interaction between the tire and the drum. By examining the existing models for the smooth surface, it is clear that there are two important factors, Which makes the tire behave differently on the flat and cilantro surface.
