Vibration testing system

Abstract

The embodiment of the invention provides a vibration testing system. The vibration testing system comprises a vibration image acquisition subsystem which is provided with a fixed clamp, a vibration table, a scale plate and a camera, and a vibration image analysis device, wherein the fixed clamp on which a product to be tested is fixed on the vibration table to cause the product to be tested to vibrate following the vibration table; the camera is used to capture a vibration image, and the camera and the scale plate are located at two sides of a symmetry axis of the product to be tested, and thecenter of the product to be tested is located on the optical axis of the camera; and the vibration image analysis device determines the position of a reference point of the product to be tested in the scale plate according to the captured vibration image, and determines the actual vibration parameter of the product to be tested according to the position of the reference point in the scale plate.In the vibration testing system, the scale plate in the vibration image acquisition subsystem provides a reference for the vibration image analysis device to determine the position of the reference point of the product to be tested in the scale plate, so as to enable the vibration image analysis device to accurately obtain the actual vibration parameter of the product to be tested.

Description

technical field [0001] The invention relates to the technical field of quality inspection, in particular to a vibration testing system. Background technique [0002] In today's era, product quality is the foundation of an enterprise's survival and development. Therefore, before the products leave the factory for sale, enterprises usually need to conduct a series of quality inspections on the products, among which vibration testing is one of the important links of quality inspection. From the production to the customer, the product will encounter various vibration environments during the whole process, such as production environment, use environment and transportation environment. Vibration testing is to check whether the product can withstand various vibration environments. [0003] In practical applications, the testing instrument can generate vibration with preset vibration parameters, and test the product to be tested according to the preset vibration parameters.
