Embodiment Construction

[0010] A hammering device applied to tire modal tests, including a base 1, a bracket 2, a swing rod 3, and a force hammer 4, the bracket 2 is welded on the base 1, the swing rod 3 is connected to the bracket 2 through a ratchet mechanism, and the force Hammer 4 is fixed on the other end of fork 3.

[0011] The working principle and usage process of this embodiment:

[0012] During the test, the tester only needs to pull up the pendulum 3, then release it, and let it fall freely to hit the tire to stimulate the tire vibration response. The tester can adjust the force of the hammer 4 to hit the tire by controlling the height of the pendulum 3. The effect of the ratchet mechanism can prevent the hammer 4 from rebounding after hitting the tire, and the tire is knocked twice to interfere with the experimental results.

Abstract

The invention discloses a hammering device applied to a tire modal test. The hammering device comprises a base, a bracket, an oscillating bar and a hammer, wherein the bracket is welded on the base, the oscillating bar is connected with the bracket through a ratchet mechanism, and the hammer is fixed on the other end of the oscillating bar; during the test, a tester only needs to pull the oscillating bar up and then release the oscillating bar to let the oscillating bar to fall freely to knock a tire to stimulate the tire vibration response, the tester can adjust the force of the hammer to strike the tire by controlling the pull-up height of the oscillating bar, meanwhile due to the action of the ratchet mechanism, the situation that the hammer rebounds after striking the tire to strike the tire for the second time, leading to interference to an experimental result, can be prevented; and the problem of uneven force of the hammer to strike the tire is solved.

Description

technical field [0001] The invention relates to a testing device for auto parts, in particular to a hammering device applied to tire modal testing. Background technique [0002] The most widely used tire modal test is still the hammering method, but the hammering method requires the tester to operate the hammer for the test and to ensure that the strength of each knock is the same, but it cannot be used every time during the test. The dynamics of the hammer hitting the tires are all the same, which has produced errors in the test results. Contents of the invention [0003] The purpose of the invention is to solve the problem of uneven strength when the hammer strikes the tire, and control the strength of the hammer by controlling the height of the hammer. [0004] A hammering device used in tire modal tests, including a base, a bracket, a swing rod, and a force hammer. The bracket is welded on the base, the swing rod is connected to the bracket through a ratchet mechanism...
