Abstract
The present investigation concerns the articulated bus with a driving from the third axle. The aim of this paper is to study the influence of the elasticity of the turntable rubber-metal joint upon the front frame load of the driving unit. Using the finite elements method it was made a 3D model of the turntable and the front frame of the second bus unit. This model gives the possibility to investigate the stresses of the dynamic loading. The dynamic efforts have to be given as an equivalent effort or displacement. They can be determine by the 3D mechano-matematical model. Different regimes of the dynamics loading are precise at the bus driving on the road surfaces by changing the connection elasticity. This model allows more correctly choosing of the materials for the frame and rubber-metal joint.
