Abstract

The invention discloses a tire three-way rigidity test device, which comprises a base, two sets of gate-shaped frames symmetrically installed on the base, a beam, a dynamic loading device, a supporting device and a clamping device, and the two sets of gate-shaped frames are The bolts are fixedly installed at both ends of the base, and the beams are fixedly installed on the top of the two sets of door-shaped frames. The middle part of the beams is provided with a downward dynamic loading device. The tightening device is fixedly installed on the inner side of the two sets of door-shaped frames; by changing the actuating head and adjusting the tire test position, the vertical, longitudinal and lateral dynamic stiffness of different types of tires can be measured on one set of devices; the installed straight line The displacement sensor can measure the magnitude of the displacement in each direction, and the force sensor can measure the magnitude of the force in each direction, thereby calculating the dynamic stiffness in each direction; compared with the existing experimental device, the structure is simple and the operation Convenient and low cost.

Description

technical field [0001] The invention relates to the technical field of tire mechanical characteristic analysis, in particular to a tire three-way rigidity test device. Background technique [0002] Tire stiffness, especially tire dynamic stiffness, is an important parameter reflecting the mechanical properties of tires, which is of great significance in the design of automobile structure and its dynamic performance analysis. [0003] At present, in the tire stiffness test, the static load is mostly applied according to the national standard, and then the vertical, longitudinal and lateral static stiffness of the tire is measured. There are few experimental machines for measuring the three-way dynamic stiffness of tires through three-way dynamic loading. The existing three-way dynamic stiffness test device realizes three-way dynamic loading through multi-layer worktables and multiple servo motors. During the test, the position of the tire does not change. The test device has...
