Abstract

The invention discloses an automobile tire vibration excitation device and method for an automobile in an amplitude adjustable running state. The device comprises a vibration excitation device body, a transmission mechanism and a tightening mechanism, the vibration excitation device body comprises a crank shaft, an upper push rod, a lower push rod and a carrier table, the crank shaft capable of structurally rotating is mounted in a lower box, a lead screw guide rail mechanism can be mounted below each individual vibrating table in order to move the vibrating table, the distance between the vibrating tables is changed by rotating lead screws, a motor is connected with the vibrating tables in a belt transmission manner, belt transmission can loose and generate slip after the distance between the two vibrating tables is shortened, the motor can be mounted on a lifting table in order to avoid slipping and tension a conveyor belt again, the conveyor belt is stretched by changing the height of the motor, and the automobile tire vibration excitation device can normally run.

Description

technical field [0001] The invention belongs to the technical field of vibration control, and in particular relates to an automobile tire vibration device and method in a driving state with adjustable amplitude. Background technique [0002] With the rapid development of the automobile industry, the research on automobile reliability becomes more and more crucial. The traditional static load test of auto parts can no longer meet the requirements of auto experiments. The automobile is a high-speed means of transportation, and its parts are subject to different loads under various working conditions. Under long-term loads, some parts will suffer from fatigue damage. The service life of the car is determined by the fatigue life of its parts. Decide. In order to ensure the reliability of automobiles, in recent years, in addition to testing on roads or special lanes, it has been possible to use automobile road simulation test devices in laboratories to simulate the vibration ge...
