VIBRATION TESTING SYSTEM SETUP

The use of vibration in Environmental Stress Screening (ESS) has expanded from the past from purely military applications until today commonly applied in the commercial sector. The use of ESS becomes a standard customer defined requirement in the aerospace and defence related products to ensure safe operation of critical equipment. Commercial product manufacturers today typically have full ESS programs in place with vibration test or combined with thermal cycling. The ESS programs are designed to comply with military and other international standards such as MIL, ASTM, IEC, ISO, BS etc.

The use of vibration in ESS has been proven to be a way to increase product reliability. It is also a tool to assist engineer in the product development process. Simulating the environment condition on the developing product will allow the design engineers to classify and analyse screening data to identify problem areas and recommend early corrective action.

Vibration testing as a part of ESS ensures the occurrence of failures in the product in early stage. These failures then occur before the units leave the manufacturing facility, dramatically improving field reliability. The optimal screening will maintain field failure cost savings.

PREREQUISITE SYSTEM COMPONENTS

1. Vibration controller required for test profiling control. ETS shakers are compatible with all major vibration controllers.

2. Signal conditioner required to provide current source for accelerometer or function as a charge amplifier.

3. Accelerometer built-in amplifier type or charge-type for signal feedback to vibration controller or data acquisition.

ETS is able to provide a complete system package with a suitable controller of your choice.
