A vibration testing device for quality inspection of an air conditioner of an electric vehicle

Abstract

This invention discloses a vibration testing device for quality inspection in electric vehicle air conditioning production, belonging to the technical field of vibration testing devices. It includes a base placed on a horizontal surface. The invention utilizes an analysis module to perform outlier statistical analysis on multiple images, effectively identifying and eliminating abnormal images caused by instantaneous light changes, lens contamination, or electronic noise, thus avoiding misjudgments that may be caused by single-image distortion. Employing a dual screening standard of "minimum number of abnormal markers" and "no abnormalities at adsorption points," the final determined "analyzed images" are of high quality and reliability, providing a stable and reliable data foundation for subsequent adsorption point optimization. By comprehensively considering three key indicators—displacement deviation, amplitude consistency, and phase synchronization—a comprehensive vibration uniformity evaluation system is constructed, accurately diagnosing specific vibration non-uniformity patterns and providing a clear diagnostic basis for adjusting vibration parameters or checking equipment status.
