冲击载荷作用下压阻式微加速度计的动态力学响应研究
Study on Dynamic Mechanical Behavior of Piezoresistive Accelerometers Under Shock Loading
摘要
Abstract
Aiming at high cost and long duration problems of tests to analyze the reliability of devices, the dynamic response of piezoresistive accelerometers under impact loadings is investigated, and the nature of the mechanical responses of shock-loaded piezoresistive accelerometers could thus be obtained. Taking projectiles with conical head shape as examples for creating dynamic models, theoretical studies on typical piezoresistive accelerometers and shock loads are conducted, and the response of the piezoresistive accelerometers are analyzed. Results show that the response of the shock-loaded piezoresistive accelerometers is determined by three constants, viz. the acoustic transit time, the time period of vibrations and the duration of the applied shock load, and the relationship among these constants, which can accurately show the characteristics of impact loadings subjected by the projectiles.关键词
