ECE Regulation №66 allows to use computer simulation to determine the durability and passive safety of buses in the rollover conditions for approval. The most common method of computer simulation is currently the finite element method (FEM). Simulation of contact interaction using FEM has several assumptions that are shown in the article. Since the bus is contacted with the rotating platform during rollover, assumptions in contact interaction modeling can lead to errors in load conditions determining and, as a consequence, inaccurate values of the bus body deformations can be obtained. Therefore, authors developed a mathematical model of bus motion, which occurs before the impact with the ditch surface. To confirm the accuracy of the systems of differential equations, the comparison of the results of mathematical modeling, FEM simulation and experiment using separate bus section are provided in the article.

Experimental and theoretical study of the models of elastic-plastic elements vehicles manufactured from alloys with shape memory effect. Dynamic tests were carried out in the area of deformation (20-30%), which allowed to achieve optimum energy absorption and return to its original position for subsequent deformation. The model proved highly efficient in terms of the one-dimensional dynamic loading, such full-scale, and allow for the absorption from 55.8 to 97.8% of the inputs, depending on the initial geometrical proportions. Evaluation of the effect of the scale factor in the simulation of elastic-plastic elements on the basis of an alloy with shape memory effect showed the possibility of transferring the results of experimental studies on a real model of the car of the future.
