振动传感器在强噪声环境下的响应输出分析

摘要

Objective To study characteristics of vibration transducer in strongn acoustic field.Methods The noise test of vibration transducer was done according to the standard of GJB 150.17-86. The response output of the transducer in the noise field was analyzed. Indicators of the transducer before and after the noise test were compared.ResultsThe performance of vi-bration transducer was proved to be normal after the noise test. The response of vibration transducer in strong acoustic field was relatively small. The acoustic field stimulated in single vibration test didn't influence test results of the vibration transducer. ConclusionThe sensor can complete vibration monitoring work.%目的 考察强噪声场下振动传感器的性能.方法 采用GJB 150.17—86对振动传感器进行噪声鉴定试验,并分析传感器在噪声场中的响应输出,对比试验前后的传感器性能指标.结果 振动传感器经过强噪声场试验后的性能正常,振动传感器在强噪声场中的响应相对较小,单项振动试验中的噪声场不会影响振动传感器的测试结果.结论 该传感器可以完成振动监测工作.
