| 摘 要： | 一种高效率、高精度的振动测量和分析方法，该方法不仅可以获得振动参数，还能获得加速度（A）、速度（V）和位移（D）（本文简称AVD值）。与传统方法不同，该方法是基于虚拟仪器及其计算机运行环境的一种非接触测量方法，通过测量与虚拟仪器实现对振动图象的数字化处理和通道扩展，测量完成后除获得震动参量外还可直接获得相关AVD值。通过实验室验证其有效性并准备用于某种发射装置振动特征值的测量。

| Abstract: | The paper introduces a high efficiency and precision vibration measurement and analysis method.The method obtain not only vibration parameter,but also Acceleration(A) Velocity(V) and Displacement(D).The different between the method and traditional is it's an untouched measurement based on extend virtual channels by virtual instrument.We can obtain vibration parameter and AVD after measure.Validity validated in laboratory,it will be used to measure vibration parameter of some shooting installation. |
