Abstract

The invention discloses a multi-angle dynamic stiffness experimental device for a tire. The multi-angle dynamic stiffness experimental device comprises a supporting device, a fan-shaped plate, a T-shaped shaft and a stamping device; the supporting device is fixed to the ground or a mounting face, and the fan-shaped plate is arranged at the right end of the supporting device in an angle-adjustablemode; the supporting device is hinged to the T-shaped shaft, and the fan-shaped plate is fixed to the T-shaped shaft; the tire sleeves the T-shaped shaft and is arranged on the inner side of the stamping device; a driving device is arranged at the top of the stamping device, and an actor on the upper part of the stamping device removably abuts against the top surface of the tire; and the lower part of the stamping device is slidably connected with the ground or the mounting face, and a measuring device is arranged on the stamping device. The multi-angle dynamic stiffness experimental device for the tire is easy to operate, high in experiment precision, low in cost and capable of testing dynamic stiffness of the tire at multiple angles.

Description

technical field [0001] The invention relates to the technical field of automobile tire performance testing, in particular to a multi-angle tire dynamic stiffness testing device. Background technique [0002] At present, the tire testing machines of most manufacturers generally only load the tire in a single direction, and measure the stiffness data in a single direction, such as only carrying out dynamic load and static load on the radial direction of the tire at 90° or loading in the axial direction of the tire, and In the radial stiffness test, only the deformation of the rim and the degree of tire air leakage after loading the tire are concerned, and the shape of the hammer is different. For example, in the current domestic wheel radial impact performance testing machine (ITM-6), the hammer It is a 150° conical block, and the test focuses on the deformation of the rim and the tire deflation under the impact of the hammer at 90°; the domestic "Impact Test Method for Light ...
