Marchete Hammering Zero-time Determin Method Based on Universal Switch
Aiming at the problem of frequent failures of acceleration sensors during signal detection in the elec-tronic time fuze marchete hammer test process,a method for determining the zero-time of Marchete hammering based on a universal switch was proposed.The universal switch was fixed to the Marchete hammer at the head position,the analog signal filter circuit module filtered the closed signal of the universal switch during the ham-mering,and monitored it with an oscilloscope or interrupt acquisition circuit to realize the determination of the zero-time of the hammering overload and provided a zero-time reference for the test signal.The experimental re-sult showed that the Marschet hammer zero-time determination device based on universal switch was of simple hardware,strong engineering feasibility,and high reliability.It could completely replace the accelerometer's ze-ro-time scheme,and greatly reduce production costs.
