摘要
阐述了二阶加速度测量系统的特点。基于A263型线加速度传感器的测量原理,分析了二阶加速度传感器动态特性的特点及测试方法,李萨如图形在相频特性测试中的应用,幅频特性的测试方法,自然振动频率fn及阻尼比ξ等动态性能的确定原则。动态特性在飞行试验数据处理中延迟时间的计算方法及仪器选择方面的应用。
The paper is to explain the Characteristics of the 2nd-Order Accelerated Measurement system. On the basis of the A263 Linear Accelerated sensor, the dynamic 2nd-Order Accelerated sensor and its test methodology are analyzed, as well as the Lissajous Graphics Application is Phase-Freq Test, Amplitude-Freq Test, Natural Vibration Freq and Damping Ratio ξ in the determination of the dynamic performance. Also describes the calculation of the processing delay in flight test data for Dynamic Characteristics, and Test equipment selection are described.
