基于超声波的动态燃速测试系统的设计与应用
Design and Application of a Dynamic Combustion Speed Testing System Based on Ultrasonics
摘要
Abstract
The burn surface recession rate of solid rocket motors is a critical parameter for evaluating engine performance.To address the demands for dynamic response and precision,a high-precision dynamic multi-channel burn rate measurement system is presented.The system consists of a host computer,ultrasonic acquisition card,transducers,and other components.The acquisition card,serving as the core of the system,is controlled by an FPGA and integrated with high-pressure pulse wave emission circuitry,echo signal processing cir-cuits,and other modules to achieve high-pressure ultrasound transmission and echo signal acquisition.The system enables real-time multi-channel parallel burn rate measurement,significantly reducing measurement errors and improving accuracy.The feasibility and measurement precision of the system are validated through thickness measurement experiments using a single-material standard test block.Subsequently,burn rate measurement tests are conducted on a Φ127 standard test engine,with a multi-target burn rate measure-ment method used as a reference.The results demonstrate that the proposed multi-channel burn rate measurement system achieves an average measurement error of<0.1 mm/s,showcasing high real-time performance,precision,and better compatibility.关键词
