Abstract

The invention discloses a measuring device for rigidity of rubber bushings. The device comprises a working table, a connecting support seat fixed on the working table, and a lower fixing bracket assembly used for fixing the rubber bushings, and further comprises a dynamic tester, a connecting shaft penetrating through inner rings of the rubber bushings, and an upper fixing bracket assembly fixedly connected with both ends of the connecting shaft, wherein the working end head of the dynamic tester is connected with the upper fixing bracket assembly to apply force to the upper fixing bracket assembly, and a ball cardan joint for connection is arranged between the upper fixing bracket assembly and the working end head of the dynamic tester. The device can be used for measuring the static rigidity and the torsion rigidity of the rubber bushings at the same time, and besides, the structure is simple, the adjustment is convenient, and the device can be applied to the field of the rigidity measurement of the rubber bushings in a standard manner.

Description

technical field [0001] The invention relates to the field of rubber bush testing, in particular to a rubber bush stiffness measuring device and a method for using the same. Background technique [0002] Vibration-absorbing rubber parts are widely used in various bushings and powertrain mounts of automobile chassis. Its main function is to attenuate engine vibration caused by road excitation or output torque fluctuations, and control chassis components and engine displacement. The rubber bushing has the following advantages: 1. Because the elastic modulus of rubber is smaller than that of metal, the effect of vibration isolation and noise reduction is remarkable; 2. The shape of the rubber is not limited, and the stiffness in each direction can be freely selected within a certain range. Properly select the elastic stiffness ratio in each direction; 3. It can be easily combined with metal parts, so that the rubber bush can bear multi-directional loads, which not only simplifie...
