Rubber bushings are key elastic components of automotive chassis suspension systems, responsible for functions such as shock absorption, isolation, force transmission, and guidance. Its performance is directly related to the smoothness, handling stability, and ride comfort of the entire vehicle.
The radial loading test simulates the wheel transmission load borne by the bushing in the direction perpendicular to the axis line, evaluating the bushing's stiffness characteristics and fatigue life under radial loading conditions.
