| Abstract: | A certain type liquid-ring angular accelerometer was introduced.Mechanism study,model analysis and test validation were carried out for its cavitations phenomenon during the development process.Combining with applying conditions and breaking through the conventional screening method of temperature and vibration,an integral screening method of temperature-vibration-shock response was presented.By this way,the fault products were eliminated or repaired,and the environmental worthiness and operating reliability was improved. |

| Keywords: | angular accelerometer cavitations screening |
