Instrument vibration testing system and application thereof

Abstract

The invention discloses an instrument vibration testing system and the application thereof. The system comprises an instrument vibration testing device, a tool plate assembly device which is used for fixing an instrument and transmitting performance parameters of the instrument under the vibration condition, a conveying positioning device which is used for conveying the tool plate assembly device with the instrument to each work position, lifting devices which are located at two sides of the conveying positioning device and are used for lifting the tool plate assembly device with the instrument, and a testing electrical cabinet which is used for detecting and recording the state performance parameters of the instrument before vibration, in vibration and after vibration. The system is used for the vibration testing of a vehicle-mounted instrument. The system can be used for the vibration testing of various types of instruments, especially for the testing of the vehicle-mounted instrument. The system can integrate the conveying, vibration and testing of the instrument into one body for continuous execution, and can control and adjust the vibration frequency through a motor regulator. The system has the remarkable characteristics of on-line vibration testing, is true in vibration simulation of the instrument, is reliable in on-line testing data, is high in production efficiency, and is low in labor intensity.

Description

technical field [0001] The invention relates to instrument testing technology, in particular to an instrument vibration testing system and its application. Background technique [0002] Whether it is a functional instrument or a display instrument, its working environment, especially the vibration environment, has a direct impact on its working stability and life. Determines the reliability of the means of transport. [0003] Take vehicle-mounted instruments as an example, common ones such as audio, CD, display, GPS, etc., their working stability and durability (life) are different in static state and in-vehicle state. In order to work stably and permanently under the condition of vibration, it is necessary to carry out the simulation experiment of the vehicle state on the vehicle instrument. In the past, when carrying out vehicle-mounted simulation experiments on vehicle-mounted instruments, the relevant performance was tested after shaking the vehicle-mounted instrument ...

AI Technical Summary

Problems solved by technology

Although this method is better than manual shaking and vibration, it still has high labor intensity and low work efficiency, and still cannot meet the requirements of a large number of instruments that need to be tested.
