Description

a binding device

technical field

The utility model relates to a binding device, in particular to a tire binding device for fixing vehicles.

Background technique

In the prior art, there are mainly three methods for measuring the center of mass and moment of inertia of an object: the three-wire pendulum method, the torsional pendulum method and the compound pendulum method. Among them, the three-wire pendulum method for measuring the moment of inertia of the object under test has the advantage of simple equipment, but its disadvantages are that its measurement accuracy is low, the installation of the test piece is time-consuming and laborious, and the test cycle is long. The principles of the torsion pendulum method and the compound pendulum method are basically the same, but the test bench measured by the torsion pendulum method, the adjustment of the various postures of the measured object on the test bench and the measurement of each relative position are not easy to get a good control, which will give the final measurement Accuracy has a great impact, and it is not easy to obtain good test accuracy.

At present, the tests of center of mass and moment of inertia are mainly torsion pendulum method and compound pendulum method. No matter which method is used for testing, the vehicle under test needs to be hoisted and placed on the test bench.

However, when the tested vehicle is placed on the test bench for measurement, it needs to be rotated or turned over with the test bench so that the tested vehicle can be measured under different working conditions. At this time, it is necessary to fix the tested vehicle on the test platform and keep its position unchanged, so as not to affect the test accuracy of the test platform.
