Work describes an approach to complex thermal analysis of buses salons starting from engine heat radiation and with its further distribution along the internal bus volume. Provided workflow chain in the article could be used as the base for any bus type climate and thermal investigation with the next optimization events. Heat analysis with materials thermal conductivity parameters was proceeded using Ansys Fluent and Ansys Steady State Thermal addons. Based on the obtained results, it is possible to draw conclusions about the impact of different parameters (temperature, heat radiation, humidity, etc) on the buses salons microclimate. Presented work could be much actual in practical plane like methodology used for efficient bus bodies development by engineers who could apply suggested materials for calculating the distribution of heat from the engine in the passenger compartment of the bus and studying the microclimate in different operating conditions. That could be especially valuable at the stage of the new bus models design and modelling.

The kinematic characteristics of the links and individual points of the mechanism are determined by the method of closed geometric contours and the method of designing plans. The forces of interaction between the links of the mechanism are determined by the method of kinetostatics, and the balancing moment by considering the dynamic equilibrium of the crank and the method of power balance. The drawbacks of the structural scheme of the mechanism are revealed and the ways of their elimination are offered. The results of research are presented in the form of graphical dependences of the kinematic parameters of the cutter, reactions or hodographs of forces in kinematic pairs. The moments of resistance forces and inertia forces are determined and the dynamic and mathematical models of the movement of the mechanism are constructed. The technology of determining the power of the electric motor is shown, and its stable area of operation is approximated by a straight line. Kinematic synthesis was performed and a modernized mechanism was obtained in which the cutter can move according to a predetermined law, in particular, without soft shocks at the boundaries of the kinematic cycle and with quasi-constant speed (error up to 5%) in the middle of the kinematic cycle
