                       Mechanical property analysis of automotive rubber bushings

                    Abstract: Bushings play a crucial role in the automotive vibration damping industry. This paper focuses
                on the rubber bushings hes of air suspensions, analyzing the equivalent stress, displacement, and stiffness of
                bushes with different structures under loads applied in various directions. The study ultimately reaches the
                following conclusions: the stress is highest at the external leakage point where the bushing frame connects
                to the rubber. During design, chamfering can be increased to mitigate stress concentration; adding an
                intermediate frame can enhance the bushing stiffness, with the maximum equivalent stress occurring on the
                intermediate frame; changing the bushing from a fully rubber type to a hollow type can reduce both bushing
                stiffness and equivalent stress.
                    Key words: bushing; equivalent stress; equivalent displacement;stiffness
