| 摘 要： | 用有限元分析软件ANSYS对一种改进的测量油膜压力的传感器进行了动力学分析,包括固有振动特性分析、谐响应特性分析和瞬态响应特性分析。通过固有振动特性分析,得到振动系统的前4阶固有频率;通过谐响应分析,得到传感器在承受随时间按正弦规律变化的载荷时的稳态响应;通过瞬态响应特性分析,得到传感器在承受实际的油膜载荷作用下的响应特性。分析表明,传感器具有较高的一阶固有频率和良好的动态响应特性。

| Abstract: | 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. |
