Suspension system of a vehicle is one of the most important components of a vehicle that directly affects the safety, performance, noise level. Designing mechanisms of suspension system of the vehicle is a very complex task. At the beginning it is necessary to realize many requirements relating to the suspension system. McPherson suspension system is most commonly used on the front of the vehicle. Its application is most reflected in better movement of vehicles through the cornering as well as in a comfortable ride. Modern methods of construction of the system and its components involve the use of certain software packages. In this paper, using CATIA software package, numerical simulations were carried out for the most important parts of suspension. Finite element analysis was performed of the entire system to analyze effective stress and deformation changes in the function parameters in the analysis.

The aim of this paper is to derive an equation for the temperature distribution in journal bearing oil film, in order to predict the thermal load of a bearing. This is very important for the prevention of critical regimes in a bearing operation. To achieve the goal, a partial differential equation of the temperature field was first derived, starting from the energy equation coupled with the Reynolds equation of hydrodynamic lubrication for a short bearing of symmetric geometry. Then, by solving the equation analytically, the function of temperature distribution in the bearing oil film has been obtained. The solution is applied to the journal bearing, for which the experimental data are available in the references. Finally, the obtained results have been compared to the corresponding experimental values for two operating regimes, and a good level of agreement was achieved.
