How to use three comprehensive vibration test benches for testing auto parts?In the application of automobile products, the temperature, humidity and vibration test bench is mainly used to test the performance indicators of automobile parts in temperature, humidity and vibration environments. It adopts a unique balanced temperature and humidity adjustment method to obtain safe and accurate temperature and humidity. Humidity environment.
Next, let’s take a look at the introduction of the three comprehensive vibration test methods for automotive products.
Test equipment: HUANYI instrument temperature and humidity vibration test bench
Test sample: instrument panel assembly
Test preparation: Before the start of the three comprehensive vibrations, in addition to the installation and fixing procedures, at the same time, the environmental operating procedures are set according to customer needs, and the test chart of a cycle of environmental testing of the instrument panel assembly is provided.
Test requirements:
After four rounds of temperature, humidity cycle and random vibration coupling tests, it is necessary that all components of the instrument panel assembly, including bonded parts, riveted parts, equipment parts, etc., should have no signs of relaxation, and there should be no stress in the plastic area due to the vibration test. There is no whitening phenomenon, and there is no shift between the wire bundles. The degree of functional decline in the major later stages needs to be assessed by oneself.
According to different test requirements, different parameters are set, such as low temperature (-30℃), high temperature (+75℃, 50% humidity), 50Hz vibration frequency, etc.
Notes, experiences and suggestions:
In order to ensure that the test can be carried out accurately and smoothly, it is necessary to pay attention to the condition of the samples in the test chamber and the monitoring of the vibration table at all times to avoid various accidents due to loose fasteners or loose sensors.
In view of the complexity of the three-comprehensive vibration test, detailed preparation and detailed analysis and calculation are required before the three-comprehensive test, especially the power-on test, and the impact of electrical noise on the test needs to be evaluated.
The above is an introduction to the application of temperature, humidity and vibration test benches in automotive products. If you have other testing questions, you can visit the official website of "HUANYI Instruments" and consult relevant technical personnel.
