| 摘 要： | 由于传感器与周围介质刚度不耦合的原因，埋入式压力传感器所测得读数并不是材料内部真正的受力状态。根据压力传感器的实际结构，采用有限元数值模拟分析方法，计算得出压力传感器的实际受力特征与应力分布规律，提出了压力传感器读数的修正方法，为压力传感器的正确使用提供理论依据和可靠的方法。

| Abstract: | The observed values of the embedding pressure sensors aren’t the actual stress values in the medium , for the sensor isn’t coupling with the surrounding medium. In this paper, The structure of pressure sensor is described firstly, then combined with the by using numerical analysis of finite element method , the real load feature and stress distribution of pressure sensor are obtained. Finally, a method to modify observation data is proposed so as to provide a theoretical foundation for applying pressure sensor correctly. |
