Problems solved by technology

[0004] At present, there are mainly two types of test institutions for this type of rubber bushing. One is to conduct radial or torsion or warping equal-amplitude tests on rubber bushings alone, but the loading form is single, which is inconsistent with the actual stress state and cannot be restored. The correct failure mode; the second is to use the method of twisting the rotating shaft and then radially loading the bushing with a linear actuator in the middle, but this method still lacks warping loads, and it will occur when radial and torsional loads are applied simultaneously Interference, leading to difficulty in test control and imprecise results

Abstract

The invention relates to the technical field of automobile part tests, and discloses a rubber bushing test system which comprises a loading seat, a warping seat and a torsion seat. The loading seat is provided with a containing hole for pressing the rubber bushing, and the loading seat is configured to apply radial load to the rubber bushing; the warping seat comprises a connecting rod, and is used for penetrating through an inner hole of the rubber bushing to fix the rubber bushing on the warping seat; and the warping seat is rotatably connected to the torsion seat, the torsion seat is capable of rotating about an axis of the connecting rod, and the torsion seat is configured to apply a torsional load to the rubber bushing. The rubber bushing test system realizes mechanical decoupling, and can simultaneously apply three dynamic loads of radial, torsion and warping to the rubber bushing, the installation and connection modes of the rubber bushing are consistent with that of a real vehicle, and the rubber bushing test system can truly simulate the actual working condition of the rubber bushing, and accurately tests the rubber bushing.

Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a rubber bushing testing system. Background technique [0002] With the development of the automobile industry, people have higher and higher demands on automobiles in terms of energy saving, environmental protection, comfort and reliability. [0003] In the guiding device of the suspension system (such as: swing arm, rear axle, etc.), the hinge point connected with the body is more and more connected by rubber bushing. Rubber bushing has become an indispensable and important component in automobiles due to its good vibration isolation performance, elastic characteristics and attenuation characteristics. [0004] At present, there are mainly two types of test institutions for this type of rubber bushing. One is to conduct radial or torsion or warping equal-amplitude tests on rubber bushings alone, but the loading form is single, which is inconsistent with the actual s...
