英文摘要：

The dynamic characters of an improved transducer measuring oil film pressure were analyzed by the using of a software of finite element analysis ： ANSYS. The analysis included natural vibration analyse, harmonic response analyse and transient response analyse. The initial fourth order natural frequency was obtained through natural vibration analysis. Through harmonic response analyse ,the steady-state response of the sensor under the load changing as sine wave with time was obtained. And with transient response analyse, the sensor＇ s response under the actual oil film pressure was obtained. The analysis indicates that the sensor has higher first order natural frequency and favourable dynamic response characters.
