Vibration Of The Comprehensive Chamber
Vibration of the comprehensive chambers reproduce the use environment of electronic instruments, auto parts, ships, aerospace and other industry products, to achieve temperature, humidity, vibration comprehensive composite test.
● Functional Features of vibration of the comprehensive chamber
According to the purpose of the test, the setting place and the fixing method of the sample, a reasonable matching mode between the test chamber and the shaking table should be selected. The test chamber and shaking table can be combined to carry out compound test, or test separately.
● Product application of vibration of the comprehensive chamber
Vibration of the comprehensive chambers are mainly used in aviation, aerospace, ships, weapons, electrical, electronic, automobile and automobile parts, motorcycles, communications, scientific research institutes, metrology and other industries to determine electrical and electronic products, instruments or other equipment in the transport, storage, use of reliability test. It is mainly made of temperature and humidity test chamber with corresponding vibration table, which can independently complete the corresponding temperature, humidity, vibration test (vertical and horizontal direction) and the combination test of three factors.
Vibrational Verification for Functionality(VVF)
In the vibration generated during transportation, freight boxes are susceptible to complex dynamic pressures, and the resonant response generated is violent, which may cause packaging or product failure. Identifying the critical frequency and the type of pressure on the package will minimize this failure. Vibration testing is the assessment of the vibration resistance of components, components and complete machines in the expected transport, installation and use environment.
Common vibration modes can be divided into sinusoidal vibration and random vibration. Sinusoidal vibration is a test method often used in the laboratory, which mainly simulates the vibration generated by rotation, pulsation and oscillation, as well as the resonance frequency analysis and resonance point residence verification of the product structure. It is divided into sweep frequency vibration and fixed frequency vibration, and its severity depends on the frequency range, amplitude value and test duration. Random vibration is used to simulate the overall structural seismic strength assessment of the product and the shipping environment in the packaged state, with the severity depending on the frequency range, GRMS, test duration and axial orientation.
Vibration can not only loosen the lamp components, so that the internal relative displacement, resulting in de-welding, poor contact, poor working performance, but also make the components produce noise, wear, physical failure and even component fatigue.
To this end, Lab Companion launched a professional "LED lamp vibration test" business to simulate the vibration or mechanical shock that may occur in the actual transportation, installation and use environment of the lamp, evaluate the vibration resistance of the LED lamp and the stability of its related performance indicators, and find the weak link that may cause damage or failure. Improve the overall reliability of LED products and improve the failure status of the industry due to transportation or other mechanical shocks.
Service customers: LED lighting factory, lighting agents, lighting dealers, decoration companies
Test method:
1, the LED lamp sample packaging placed on the vibration test bench;
2, the vibration speed of the vibration tester is set to 300 RPM, the amplitude is set to 2.54 cm, start the vibration meter;
3, the lamp according to the above method in the upper and lower, left and right, front and back three directions respectively test for 30 minutes.
Results evaluation: After the vibration test, the lamp can not occur parts falling off, structural damage, lighting and other abnormal phenomena.
The Relationship Between the Altitude of the Standard Atmosphere and Air Temperature and Pressure
The standard atmosphere referred to here refers to the "1964, ICAO Standard atmosphere" adopted by the International Civil Aviation Organization. Below an altitude of 32 km, it is the same as "1976, U.S. standard atmosphere". Changes in air temperature near the surface (below 32 km) are:
Ground: The air temperature is 15.0℃, the air pressure P=1013.25mb= 0.101325MPa
Temperature change rate from ground to elevation 11 km: -6.5 ℃/ km
On the 11km interface:
The air temperature is -56.5 ℃ and the air pressure P=226.32mb
Temperature change rate at elevations of 11-20 km: 0.0℃/ km
Temperature change rate at altitude 20-32 km: +1.0/ km
The following table lists the temperature and pressure values of the standard atmosphere at different altitudes. In the table, "gpm" is the altitude meter, and its negative sign represents the altitude

First, different environmental conditions will have different effects on parts and cause them to fail, so the parts of the car need to be tested according to the relevant specifications to meet international requirements and meet the foreign market, the following is the correlation between different environmental conditions and product failure:
A. High temperature will make the product aging, gasification, cracking, softening, melting, expansion and evaporation, resulting in poor insulation, mechanical failure, mechanical stress increase; Low temperature will make the product embrittlement, icing, shrinkage and solidification, mechanical strength reduction, resulting in poor insulation, cracking mechanical failure, sealing failure;
B. High relative humidity will make the product poor insulation, cracking mechanical failure, sealing failure and resulting in poor insulation; Low relative humidity will dehydrate, embrittlement, reduce mechanical strength and lead to cracking and mechanical failure;
C. Low air pressure will cause product expansion, electrical insulation deterioration of the air to produce corona and ozone, low cooling effect and lead to mechanical failure, sealing failure, overheating;
D. Corrosive air will cause product corrosion, electrolysis, surface degradation, increased conductivity, increased contact resistance, resulting in increased wear electrical failure, mechanical failure;
E. Rapid temperature changes will cause local overheating of the product, resulting in cracking deformation and mechanical failure;
F. Accelerated vibration damage or impact will cause the mechanical stress fatigue resonance of the product and lead to an increase in structural damage.
Therefore, products need to pass the following climatic tests to test the reliability of components: Dust (dust) test, high temperature test, temperature and humidity storage test, salt/dry/warm recovery test, temperature and humidity cycle test, immersion/seepage test, salt spray test, low temperature test, thermal shock test, hot air aging test, weather and light resistance test, gas corrosion test, fire resistance test, mud and water test, dew condensation test, high variable temperature cycle test, Rain (waterproof) test, etc.
