半球谐振陀螺线振动试验分析

半球谐振陀螺是一种新型振动陀螺，加速度会对其造成影响。为了研究线加速度对半球谐振陀螺性能的影响，利用谐振子环形运动方程，推导了线加速度对半球谐振陀螺工作性能影响机理。设计线振动试验，通过小波分析试验数据，检验不同线加速度条件对半球谐振陀螺输出的影响规律，并通过对试验数据的方差分析，检验线加速度对半球谐振陀螺输出精度的影响。由理论推导和试验分析可知，线加速度对半球谐振陀螺输出影响较小，可以忽略。

Linear Acceleration Test and Analysis of HRG

HRG is a new kind of vibratory gyroscope whose precision can be influenced by acceleration. In order to analyze the influence by linear acceleration and test the performance of HRG, firstly, the mecha nism of influence by linear acceleration on HRG was deduced based on circular motion equation of resona tor. Then the linear acceleration test was designed. The law of influence on output of HRG by different lin ear acceleration was analyzed by wavelet analysis. The influence on output precision of HRG was tested by analysis of variance of the test data. According to the theoretical derivation and test analysis, the influence on output precision of HRG by linear acceleration can be ignored.
