Vibration Test and
Why? |
||||||||||
| The use of vibration in Environmental Stress Screening (ESS) has expanded from the past in | ||||||||||
| 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 engineers in the product development process. Simulating the | ||||||||||
| environment condition on the developing product will allow the design engineer to classify | ||||||||||
| and analyze 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 | ||||||||||
| infantile period is precipitated "artifically". These failures then occur before the units | ||||||||||
| leave the manufacturing facility, dramatically improving field reliability. The optimal | ||||||||||
| screening will maintain field failure cost savings. | ||||||||||
How To
Setup Vibration Test System? |
||||||||||
 |
||||||||||
| Prerequisite System Components | ||||||||||
| #1 Vibration controller required for test profiling control. TMC 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 bulit-in amplifier type or charge-type for signal feedback to vibration | ||||||||||
| controller or data acquisition. | ||||||||||
| TMC is able to provide a complete system package with a suitable controller of your choice. | ||||||||||
