基于ICP传感器的存储式冲击波超压测试系统
A Stored Overpressure Measurement System Based on ICP Sensor for Shock Wave
摘要
Abstract
Considering the deficiency of measuring method for shock wave, an overpressure measurement system is designed by applying the storage measurement theory. An ICP pressure sensor with excellent performance is selected as the sensing component based on the performance comparison between different pressure sensors, then the excitation circuit and signal conditioning circuit are designed seriously. The digital logic circuit is performed by using a microcontroller in combination with a CPLD, which improves the intelligence and reliability of the system with a reduction in size. After calibration, the reliability and validity of the proposed system are further verified by applying it to actual measurement experiments. The measurement results for a certain bomb are also given out, including overpressure curves, positive pressure time and impulse.关键词
