The Impact Study of Dynamic Lineartest Method for High-gAcceleration
摘要
Abstract
High g dynamic linear acceleration sensor test describes the relationship between input,output and frequency of the sensor between the three,reflecting the linear characteristic at a particular frequency of the sensor.Based on a key technology Hopkinson bar system dynamic linear calibration tests by implementing internal Bomb bomb two synchronous projectile impact,in order to achieve two bullets in the role of shock acceleration pulse rod same frequency,dynamic linear acceleration sensor test.Based on dynamic linear test method,the synchronization methods and the bullet hit a bullet shape of the simulation and experimental study.The results show that:the laboratory was unable to achieve internal and external shells hit the same speed asynchronous;will be used for dynamic testing of internal and external linear elastic bindings and change internal and external elastic cross-sectional area of the first wavelet compression does not affect the present;this conclusion for the use of Hopkinson Bar do dynamic acceleration sensor calibration provides a theoretical basis and practical basis.关键词
