Abstract

The invention discloses a multi-degree-of-freedom device and a high-precision lamp vibration simulation system and method thereof. The system comprises a mounting base, a multi-degree-of-freedom movement mechanism and a clamping device. The bottom of the mounting base is connected with a vibration working platform, the top of the mounting base is fixedly connected with a rack in the multi-degree-of-freedom movement mechanism through a bolt, the inner side of the mounting base is matched with a sliding block in the multi-degree-of-freedom movement mechanism, the acceleration sensor is mounted at the tail end of the multi-degree-of-freedom movement mechanism, the clamping device is fixedly connected with a floor of the mounting base through bolts, and the clamping device clamps the cylindrical surface of the tail end of a linear motor. By controlling the multi-degree-of-freedom movement mechanism, translation and rotation of the coordinate system in the X direction, the Y direction and the Z direction are achieved, the installation angle after a lamp assembly is loaded can be accurately simulated, and the acceleration sensor is used for detecting the resonance frequency of the device. According to the invention, the installation position and angle of the lamp after loading can be accurately simulated, and the reliability of the system is ensured.

Description

technical field [0001] The invention relates to the field of detection of automobile lamps, in particular to a vibration simulation system and method based on a multi-degree-of-freedom device and a high-precision lamp. Background technique [0002] Automobile lamps are an important part of the car. As an important part that affects driving safety, automotive lamps have higher and higher reliability requirements. Automobile lamps produce violent vibration and instantaneous impact during transportation and use, and the lamps are subjected to vibrations of different amplitudes. These vibrations will pose a great threat to the strength of the installation structure of the lamps and the assembly method of the internal parts of the lamps. Therefore, the vibration test of automobile lamps is an extremely important item in the reliability test project of lamps. We need to simulate and evaluate the reliability of the installation structure strength of automobile lamps and the assembl...
