本文利用双通道信号分析仪与微机的联机系统,开发了双传声器测振技术.从理论上研究了该方法的测量误差,做了同加速度拾振方法的对比实验.结果表明:它不失为一种有效的测振方法.
In this paper, a dual-microphone vibro-acoustic technique was developed by using a dual-channel signal analyzer and a computer-based on-line system.Measurement error of this method was studied theoretically and a comparison experiment with the method of acceleration pick-up was made.The result shows that it is a Effective vibration measurement method.
