| 中文摘要: |
| 介绍了某型装备液环角加速度计特点， 对研制过程中出现的空化现象进行了机理研究、 模型分析和试验验证。结合装备实际工作环境， 突破传统的温度、 振动组合筛选方法， 提出了温度－振动、 冲击响应谱综合应力筛选方法， 剔除或修复故障产品， 从而提高产品的环境适应性， 保障装备的工作可靠性。 |
| 英文摘要: |
| 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. |
