Tension-torsion fatigue test bench for automobile flywheel plate

Abstract

The invention relates to a tensile-torsion fatigue test bench for an automobile flywheel plate. The test bench comprises a base, a flywheel plate fixed plate is arranged on the base, a torque applyingdevice applying a torque to a to-be-tested flywheel plate is arranged on the base, at one side of the flywheel plate fixed plate, an axial force applying device applying an axial load on the to-be-tested flywheel plate is arranged on the base, at the other side of the flywheel plate fixed plate, and the torque applying device can move axially together with the to-be-tested flywheel plate under the action of the axial force applying device through a guiding structure arranged on the base. According to the tensile-torsion fatigue test bench for the automobile flywheel plate, when an axial displacement test and a torque test need to be performed simultaneously, the torque applying device is used for applying the torque to the to-be-tested flywheel plate, the axial force applying device is used for applying the axial load on the to-be-tested flywheel plate, the torque applying device moves axially together with the to-be-tested flywheel plate through the guiding structure, so that the axial displacement test and the torque test can be performed simultaneously on the automobile flywheel plate, and the application prospect is good.

Description

technical field [0001] The invention relates to a test bench, in particular to a tension-torsion fatigue test bench for an automobile flywheel disc. Background technique [0002] At present, with the rapid development of the automobile industry, the performance of automobiles is constantly being improved and enhanced, and the automobile flywheel plays a vital role in the performance of automobiles. In recent years, the demand for fatigue life and reliability evaluation of automotive flywheel products under various loads has become increasingly strong, but there are currently no relevant standards and special equipment for tensile and torsion fatigue tests of automotive flywheels. Most manufacturers and testing organizations use simulation tests on actual running hosts. The disadvantage is that they cannot be scaled and replicated, which greatly affects test efficiency and scale. Contents of the invention [0003] The object of the present invention is to provide a tension...
