【Abstract】 In this paper the principle and measuring circuits of a piezoelectric sensor with floating-cam for measuring impacts are discussed.The peak value of impact wave and the effect of technical parameters on the impact force are obtained by analyzing the measured impact wave of the needles acting on the clearing cam for different clearing angles. Such a sensor proves to be an effective measuring instrument for the purpose of scientific research and actual production.更多还原
