Inertia Measurement Methods Based on Minimum Zone Condition System Recognition Theory

介绍了一种基于最小条件系统识别理论的转动惯量测量方法。测量时被测工件安装在定轴测试系统上,采用加速度传感器检测系统的自由摆动信号,应用LabVIEW软件和最小条件方法计算系统的固有频率,并依此计算工件的转动惯量。文中给出了计算机设计流程图。最后应用实验的方法验证了系统的可行性。

This paper introduced an inertia measurement methods based on the minimum zonecondition system recognition theory. When measured,the measured workpiece was installed in the fixed axis testing system.It used the acceleration sensor to detecte the system＇s free swing signal.Application of Labview software and the minimum zone condition method was used to calculate the system natural frequency. And calculate the workpiece＇s moment of inertia.This paper presented a computer design flows.Finally,the feasibility of the system has been authenticated by the application of the experimental method.
