| Abstract [eng] |
The final Master thesis analyses car anti - roll bar construction, operating principle, its types and stiffness. Sway bars can be: detachable, torsion, from carbon fiber or various different geometrical figures. In the research is used „ Ansys parametric design language” and „ SolidWorks “programs to model anti-roll bar. It also analyses standard anti-roll bar shapes. For the counting is used three different ways: analytical, solid189 and solid187. To try, the model that was made from a standard car anti-roll bar, was used the tension test. To accomplish more accurate results, while modeling anti roll-bar, in the research the material is selected by the results of previous tests. Furthermore, the geometrical characteristics are measured very carefully, because of its influence on the anti-roll bar stiffness. The differences are evaluated after all the results are compared with each other. Also in the final Master thesis was made a parameter correlation. This correlation shows that, anti-roll bar weight has a direct connection with external anti-roll bar size, and that the external diameter has indirect connection with stiffness. |
