Their mission is to provide out-of-the-box and brilliant amenities through analytical procedures and methodologies, that help organizations and industries, small or large, to attain predictably, improved, cost-effective product quality levels while sustaining the integrity in testing procedures. 

VIBRATION OR SHOCK TESTING

Vibration Testing impersonates the circumstances of a product or a structure that they might see during their lifetime while under a testing environment. Envisioned to certify that products are robust and perform safely during their transit, vibration testing spots performance issues and potential failures before they begin.  

It’s generally distinguished based on mechanical shock testing and its application for different periods which may vary from a few minutes to weeks. 

Furthermore, to produce a defined vibration, they use electromagnetic vibration exciters/shakers. It helps convert the electric signals into mechanical movements that are further controlled to uphold the vibration force or its level as per specified norms.

WHY VIBRATION TESTING?   

Vibration tests are done on various equipment’s, but yes, there are lots of reason behind the application of its analysis. The foremost reasons include-

• Rather than the definite vibration level, the response to the vibration force is recorded to determine the dynamic properties of the objects. So, they try their best to find out the aptitude of those objects to transmit the vibration and its modes at resonance.
• Moreover, at a prearranged vibration level, the vibration test is obligatory to associate the transducers to be calibrated and the reference transducer.  

PURPOSE BEHIND VIBRATION TESTING

The tests are carried out with exceptionally severe vibration level, ever recorded. The core purpose behind this is to determine the stimulated life of the product by performing the test for hours, days, and even weeks. 

Such severe tests include Highly Accelerated Life Tests (HALT) and Environmental Stress Screening (ESS), which helps in reporting the units that make sure the rigidity of the product to the customer, once the product lasts the test without losing its anticipated remaining life. 

APPLICATIONS OF VIBRATION TESTING

FREQUENCY RANGE- For objects that incite in the shipping environment, the frequency of the test stays between 5Hz and 3kHz. It’s because of some products that are exposed to higher vibration levels during transportation.

ONE AXIS- Vibration tests are generally performed one axis at a time rather than in all the three axes. Exciters used for the test are made to shake the product within the vertical direction and to hide the complete axis; the object is rotated to apply vibration in all the directions.

FOR LARGE SAMPLES- Considering the larger samples, they are shocked horizontally instead of vertically because of some functional reasons. In this case, the slip table consists of an enormous metal plate, which helps keep the weight down, a large granite block, and endlessly pumps lubricating oil.

RESONANCE- The vibration response, which is higher than the vibration input, is known as resonance. To look for resonance and perform the tests with substantial resonance frequency, preliminary sine sweeps, or random tests takes place.

AEROSPACE ELEMENTS- Ordinarily, aerospace components face challenges like temperature, volatile weather conditions, atmospheric pressure, or heavy loads issues. Due to these issues, is why dynamic measurement application count analysis, ground vibration tests, and acoustic tests, ranging from the analysis of the products to large channels.

AUTOMOBILE INDUSTRY- The manufacturers of the automobile, industries are under the constant pressure of producing long-lasting automobiles, and vehicles with well-managed NVH (noise, vibration, and harshness) qualities. Consequently, the appliance of the vibration tests varies from acoustic, rotational, and structural testing. 

Sigma’s qualified engineers guarantee the quality of the standard of the product by tendering a varied range of vibration and shock testing. Having years of experience and knowledge, Sigma can help you determine the best designs for your products and their reliabilities.
